Had a great experience. Nice looking store and knowledgeable, friendly staff and management. Purchased some surplus/expired items via their Craigslist ads for non-grow purposes. Location is industrial/warehouse with easy parking. Writing a positive experience just in case others saw the CL ads and weren't sure. read more

Been going here for years. Owner and the main employee working the front are knowledgeable and very helpful. Prices are also better than Amazon and always in stock. Great small business that really has it down. read more

I go to Hydro-Connection for the majority of my growing supplies. I love that they are open relatively early, and stay open until 6:00pm. What sets them apart is Jose! Jose is very knowledgeable as well as generous with his knowledge of all things botanic. That, combined with great customer service, and a surplus of a wide range products, makes Hydro-Connections a "go to" for me! Arthur Higgins (Frisco Farms) read more

A great place to do a CO2 tank exchange. They charged ~$25 to to exchange my empty 20lb tank for a full one. I think they are the cheapest place in the area to get co2 to use for making soda/seltzer/beer. read more

Since it's located deep in the city, I avoided this trip many times and settled for online services. I was told my desired product was readily available and there was plenty! I pull up and I was greeted be Jose, a very knowledgeable, friendly, and attentive employee. He recognized my voice and told me to back my car in so he can load. WOW first class service! As I'm looking around I begin asking Jose tons of questions where he provided answers. I even picked up a few more things because of Jose's recommendation. They got what you need look no further this is my new spot for my girls (plants) and the prices are on the money! read more

Great spot and an amazing selection! Found a consistent supplier of my nutrients and a group of guys that are both knowledgeable and care about what they do! The owner and his team make sure that you leave feeling like you had a great experience! Thanks! read more

I got it in my head that I need a new hobby. I chose a pretty complicated one; I was extremely confused about where to start and what I needed. Well I'm lucky I chose to come here. Jose helped me - he spent more than an hour walking me through the whole setup process, helping me choose the right equipment. He was a lifesaver, I don't think I would've been able to get started without him. This place is great - come here for all your hydroponic needs! read more

Amazing place. Jose was fantastic in helping me select the lights for my new garage - microgreens farm. He's funny, smart, creative and downright entertaining while be perfectly helpful. I'm now viewing my house very differently . . .how and where I can farm indoors and go beyond microgreens. read more

Oh man ! I've found heaven in my backyard. This place is my new "go to guys" for ALL my garden needs. With the recent recreational status, a HUGE price increase was thrust upon us. Ive decided to take a proactive approach and grow and make yer own. These guys and this place makes it possible. I will return ! Michael B Former president of SPARC dispensary. read more

I honestly haven't been there since my first time in early 2020, (PRE-Covid) because l do not go out too much these days, at all, but a woman in the Bromeliad Society of San Francisco recommended it for buying pumice and other planting mix products. So, l went there one day, and it seemed a little off-the-beaten-path, south of Islais Creek on Custer a two block long street between 3rd Street and 280 and near Living Green Design (also on Custer) and Flora Grubb on Jerold, do you could plan a "Three-Fer", as long as you are going down that way! Okay, so l walk in, and it's not "fancy and fluffed" like the Flora Grubb retail space. I realized l was probably in a pot-growers' paradise, because they had lots of stuff with spacey sounding names, etc. Hey, maybe l should have figured it out by the name "Hydroponic Connection", huh? But, never one to be intimidated, I asked for what l came there for, and they had it! They even had a ph test kit (Cacti Growers know the Elton Roberts discovery that by adding some vinegar to your water, your plants will do better because they like a certain ph, and that is NOT what comes out of your tap! But, you need to test your water's ph before you know how to adjust it.) Boom! I crossed that one off my list! Anyway, please don't be put-off by the warehouse feel or the fact that you're just a "Regular plant-lover/Gardener" and not a pot farmer, because they'll treat you well, in other words, just the same! They were even nice enough to load my car for me!!! Next time l go back, l will take some photos to post! read more

These guys got it all at competing prices. Tons of stuff in stock and easy to source whatever they don't have. My go to spot in San Francisco read more

I might have an unusual take on this little grow shop because I have the unfortunate luck of having to make multiple trips to grow stores and spend LOTS of time chasing down product. But here's why I give them 5 stars: Free parking and LOADING in San Francisco. Like... you can load your car up with the heavy items inside if it's raining... If you don't load inside, these guys always offer to help bring items to your car. There's a bathroom. And it's clean :) There's coffee, tea, and water in the lobby to enhance your shopping experience. These guys are always willing to bargain - has to be the best grow shop and best grow advice I've seen to date. I've seen some larger stores offering good prices, but these guys never take advantage of naive customers who wander in with wads of cash and no experience. The will even tell you how to grow weed...errr plants... over the phone! Lol. I've been shopping here for over a year and I've only had a few hiccups with some random, special order items. If they don't have what I need in stock, they can usually get it in within a day or 2. read more

The Hydroponic Connection - All sorts of delicious microbials for growing weed, grow shop for all gardeners! - Hydroponics Near Me - San Francisco, California

Just went over there had to leave what a freakin joke of a place I'm not trying to hurt your biz but you need to get some folks who can communicate and have some knowledge of what's going on around these parts I waited way too long in line and I even called before and tried to get some questions answered but no one can do that so covid or no covid y'all suck balls read more

I'm completely new to hydroponic growing so have been shopping at HC several times and each time everyone I've worked with has been extremely helpful. I mostly work with Jose who has gone well out of his way to help out even though I'm not a professional grower and simply learning to grow tomatoes, peppers and strawberries. I can highly recommend the crew at HC for whatever your level of gardening. read more

People there does not care about your experience, they only care that you do business with them on that day. I believe their business practice is to get your business the first time, who cares about repeat customers.. When you get a broken item from them, good luck getting refund or exchange. I have spent a considerable amount of money here and yet they are still unwilling to help with the broken item. I picked up and brought back the item same day. I have not even used the item, I opened the box to see the item is damaged with missing parts. I will not be buying from these bunch of people again, their prices is not great anyway, decently priced, most items can be bought online at least 20% cheaper. read more

While this was still among the worst buying experiences I've ever had, HC did make everything right in the end. (See the update below.) On 02/01/2011, I arrived at the store with a purchase order valued in excess of $2000. This PO listed explicit item descriptions and part numbers for each item. All items listed were: 1. The precise specification for my need. 2. Available from Hydro-Farm or Sun Light Supply, large distributors in the Hydroponics industry located in Northern California. Out of the gate, Sales Person 1 began to tell me what I 'should buy' instead of what was listed on the PO. He did this with five of the first six items. In one instance I agreed with him. I had listed ballasts from company "L". He 'recommended' ballasts from Company "Q." I was informed they had to order some items, thus my order would be ready to be picked up in three days (2/4/11). I then PAID IN FULL FOR ALL the listed items. I requested that I be called when the complete order was ready. I left them a copy of the Purchase Order that included my contact info. 2/4 came and went without my hearing a word. I actually didn't mind this at first because I was still busy with other aspects of my project. I actually waited until 2/15 before going to pick up my merchandise Upon arrival I was told there were still multiple missing items. When asked why I had not been called Sales Person 1 said he had LOST my original PO. I had paid via Credit Card and they took a copy of my driver's license, so obviously they had my name and address? Yet they couldn't be bothered to make a minimal attempt to contact me? Can you say 411 or ZabaSearch? I also learn two of the missing items were those ballasts Sales Person 1 recommended. They were in stock on the day I paid for them? The salesman stumbled and mumbled about then offered yet another substitute. Unfortunately this latest substitute lacked a feature found on both my original choice and on his recommended substitute. Sales Person 1 had also neglected to tell me that I needed to purchase additional adapter cables to connect the Company "Q" ballasts he recommended to the lights I was purchasing. Wanting to avoid trip after trip to the store I again asked to be called when the correct items were ready to go and left my name a phone numbers a second time. Things went further down hill from there. Three days later after again hearing nothing from these folks I went to pick up whatever was available because construction time was passing. This time I encountered Sales Person 2. It was pouring rain and in our haste to get the car loaded I failed to notice that two items I had ordered were not loaded into the car, an air pump and a box of ducting. I let it drop for the moment because of what happened next. One of the items I had originally specified was a particular air filter. Sales Person 2 tried endlessly to sell me an air filter easily 2.5 times the length/diameter I specified. There was simply no way I could adapt this gargantuan filter into my project. So I returned it and tried every way I could to explain my space limitations and how I needed a smaller filter. Being reasonable though, I tried one more of Sales Person 2"s 'recommendations.' This filter also was not acceptable. When I returned the second filter, I brought along pictures of a facility almost identical to what I was building. Even with pictures to guide him, Sales Person 2 was unable to grasp that you cannot put a 36" long object across a 31" space. In hindsight, the pictures seemed to exponentially increase Sales Person 2's determination to sell me only what he had on hand, appropriate to my needs or not. It is now February 19 and the second incorrect air filter 'recommendation' was the last straw. I was through with this company. At this point, I asked that the money for the remaining items be refunded so I could purchase them elsewhere. Rather than helping me locate another source for the missing items I'm told they have a No Refund-Store Credit Only policy. They 'assured' me they could get me the appropriate items if only I just kept on waiting. Sales Person #2 sprinkled this conversation with insistence their customer service was nothing short of superlative and with warnings that if I did not accept their 'advice' I'd possibly end up in jail since that already happened to another of his customers who didn't listen to them. I spoke with owner Steve Jones over the phone and explained my frustration. He agreed to a refund under the condition I agree to to wait for three items he normally did not stock and had "special ordered just for me." I graciously agreed to this. That was on Feb 19. Today is March 3 and I am still waiting for the phone call to come pick up the missing items. UPDATE 3/17/11: After writing to the owner of HC detailing the trouble I had in making my purchase, I was finally contacted by these folks. A full cash refund for all the missing items was issued. read more

Huge selection of liquid and solid fertilizers. The guy at the counter was very helpful and knew exactly what I was talking about and where the right product lived in the warehouse. This place is no-frills-attached, exactly what you want when you know what you want. Seems like these guys specialize in bulk orders, so maybe don't head this way to get just a tiny amount of something. In addition to fertilizer, I asked about HydroTon because I've had difficulty in the past finding it and, no surprise, they carry it here. Excellent experience. read more

Amazing service and selection. Got exactly what I needed! And the prices are very reasonable. Big fan of Jake and Jose.

This is a great shop to get everything you need to grow. The products are the best and they're prices are amazing. They are in a discrete location with little to no traffic and parking. Jose who works Monday and Sunday He is The Best. He got me RIGHT! And kept me smiling and laughing the whole time. Most pleasant purchase I've ever made. I also left with knowledge that I did not have before. My plants are healthy and eating good because of him. read more

Great shop. Knowledgable staff. Discounts on large volume purchases. Super friendly. Phenomenal selection of quality products.

I tried returning a fan, clamp, and duct, and it was so difficult because of the landscape architect and a guy named Cole. At first they said they wouldn't refund my money and that I would have a credit to my account. I explained otherwise. Then the landscape architect started telling the manager that they might have to call the police and that I was reaching over the counter. I told him there's a camera right there! Call the police. It'll be fun. They didn't call the police. So the landscape architect started to walk away. Then Cole, after I got on the phone with my credit card company, made only a partial refund to my credit card that I didn't notice until I got home, but my credit card company helped me out.

Couldn't ask for better service and I can't wait till I need some more help! Thanks Hydroponic Connection! read more

Still growing, and still going, to the hydroponic connection. Always helpful and helping us take our garden to the next level.

Been coming there awhile as well.. some of the employees are kind of d-bags.. one sylable answers grunted at you and then full price if you don't feel like haggling. I guess I'm not cool enough.. Maybe this shop is only for "thier boys" or something.. a dark wharehouse with the exact same stuff all the other hydro shops have.. go to Grow Your Own or Berkely Indoor Garden if you want deals and normal non douchebag 20 somethings.. notice how most positve reviews are from 2011? the best one from this year is "it's like going to your boys house to pick up hydro equipment" that is precisely why this place is goofy.. besides the fact that it is in some wherehouse in the Bayview if they don't like you for whatever reason, don't expect much.. matter of fact don't expect much either way.. read more

Your one stop shop for hydroponics. Knowledge staff. Reasonable prices. Support the small businesses.

If you have wheels, then this is hands down the spot to go. They are on top of having all the cutting edge equipment and have the Best prices.

Its like going to your homies house to go pick up supplies, these guys are down and can help you in your newest or age old endeavors. read more

We went here to learn more about how to treat our positively growing plants.. Dalton, our clerk, recommended some Bloom Enhancer.. and so 80 dollars later we brought home his recommended products.. we did a test on half of our plants to see how they would react.. I'm sorry to say they rotted and died and the other half is in tact.. we went back to exchange our purchased products that we used only 1 time.. Dalton was there and kept taking our pictures of our dieing plants on our phone back to his brother to ask what to do.. I asked if his brother could come out to speak with us but he was too busy to be bothered.. Then Dalton relayed we would have to come back again because his manager was the only one who could help us.. we couldn't recall the nickname we were supposed to give our account and were sent away:( These guys are surely scamming the public and taking your money with no power to make it rite on the spot.. Really discouraging experience Even though he remembered us coming in.. read more

Wow, these guys can't be any nicer, more knowledgeable. On top of that, prices are also great! The only down side is that there's no marked prices on anything, and hydroponics gears are not cheap. they are perfectly happy to show you by checking on the computer. But I'm the kind of person who has a cash register running in my mind when I shop, so it bothers me. When I finally checked out, it was cheaper than I expected. Definitely will come back again. read more

I love this store - it has everything needed for a perfect garden. If they don't have it, they direct you to another store that does. They were also very clear about when delivery of goods will arrive when they ran out of a product I needed (never in the dark, unlike the fellow with the long statement). The sales people really want to help make it happen for me. They are full of good information and may be willing to give a better price for a product if you buy in bulk or if you simply ask. I said to one of the sales guys the price of a tray at another store, and not only did he match the price, he offered a lower price- which was really not necessary ( but awesome) as matching the price is fine for me. Anyway, I will be going back to this store, it has most of the things I need and it's fun to see some of the new products in the industry-Im always luving a new idea. Thanks THC- my project is coming together better than I could of ever imagined. Sincerely, SGM of SF read more

Had a good experience. Went to get potting soil. There's a good variety of quality products and the person there seemed to have a good grasp of the characteristics of each. Very accommodating to our particular needs. A pleasant experience, while limited, without hassles. read more

Always a pleasant experience with the staff, they ALL know their stuff. Always available to find anything or help load the car. Not no mention easy parking. Cole was really accommodating last time I was there. I was frustrated with a pH meter but he had great product knowledge and was able to ease my frustration with his calm manner and sense of humor, A+ for customer service, thank you Cole! You guys ROCK (especially Jose and Cole). read more

not a bad spot ... they carry what Plant It Earth doesnt .... so that makes it easy ... they will match internet prices .. and order anything you wanna get they dont have ... kind of hard to find .cause its tucked away in a high fenced off parking lot ... look for the opening in the gate ... read more

Jose greeted me within seconds of entering the store. He was awesome! He gave me a wealth of knowledge and was very patient with me. Most shops are hit or miss with customer service, but I get consistency with Hydroponic Connection. He walked me through my options and gave me my trade offs. Patience was vital to me considering I am a Rookie. Best prices and If there is better they match it! Thanks for the experience Jose! read more
