One of the best and most complete selections I have ever come across. The dudes there know their stuff and can also help point you in the right direction if you are compeatly lost. One stop shop no doubt about that. Adolfo riv read more

I've been to Greencoast twice so far in the past week and I must say, they really have had everything I would need to setup any type of hydro setup I wanted. I personally went with a DWC bucket setup, but that really doesn't matter in this review, what does, is, everything was priced low and i found all the answers I needed. The store has a very large selection and the prices are some of the best around so really no complaints. :D read more

This is the best hydroponics store I've ever been to, plain and simple. There's a reason I drive over 30 minutes every time I need something. It's true they have amazing prices, but rather it's their expert knowledge that keeps me coming back time and time again. The guy from Colorado who's always wearing a hat is the one you want to talk to- bar none one of the best experts I've ever spoken with. They'll set you up with the tools you need and I mean that more than just literally! read more

I'm glad I chose Green Coast in Orange. Friendly and knowledgeable staff helped me find everything I needed and more! Thanks to Maida and Kai for all their help. I'll be returning for the great service. read more

I went to my local Green Coast because my favorite hydroponics store in Santa Fe Springs was out of the soil I needed. I was concerned when I arrived that all the pallets of soil were kept outside in the sun and weather. Ever heard of bioactive soil? Strike one. There was a big sign outside that said they matched competitors' prices but when I said my hydroponics store has fox farm $3 cheaper/bag the man helping me said that it was on sale and the higher sale price was the best they could do. False advertising. Strike two. The highest grade of soil they had was Fox Farm, but I needed soil, so I purchased it. I usually get Roots Organic soil for the price they charged me for Fox Farm on sale. When they pulled the bags to put in my car one of the men said the soil was wet and heavy. It had been on one of the pallets outside in the recent rain. When I got home, I noticed that the bags were all pull dated. Every bag had passed its expiration date by 4 months. Biological activity is guaranteed to be dead by the manufacturer. I can get pull dated Fox Farm 24hr/day on Offer up for $6. Strike three. I don't know if all Green Coast stores have the same business practices, but I will never purchase from one again. read more

Great selection, prices and staff. Always helpful whenever I have a question or need to reach something on the top shelf.

The staff here is super helpful! You will find everything you need here for your planting needs. They have soil, fertilizers, planters and more! Use the 1 time check in offer too! $10 off $20. Awesome! read more

These guys will lie to you for a quick buck. Do not trust under any circumstance. Listening to one of these guys describe why one should buy a proper greenhouse made me cry on the inside, he did not know what he was talking about. No good, this place. read more

I was a regular customer for about 5 years at the Orange branch. This year things changed. New staff not as friendly, or as helpfull. Every time I go to buy a couple of bags of vermi- soil, I get hassled over the price. I've been paying 15 for a bag since you started carrying it. Yesterday I was charged 17, after I explained that it's been 15 for over a year and a half. I'm tired of the lack of service, etc, so I'm not coming back. Oh, and for what it's worth, I've been to your store a couple of times when at 10:15 am your still not open ! What's up w/that ? read more

Great customer service and are willing to answer all questions. I am going to miss them when i move to Texas!

Called ahead and was here just before closing. Dude wouldnt wait for me 5min and closed up. Saw them driving away as I drove up. Wutever. Guess they didnt need the $$$. read more

First time trying out to grow hydroponics style, Tim is very nice to offer me tips and products to start my project.

Came in to pickup supplies to build a bucket system and also nutrients. I'm relatively new to growing and Tim took the time to go over with me different nutrients and explained the differences and uses for them and made everything really simple to understand. Thanks for being so helpful and knowledgeable! Will definitely be back! read more

They got all kinds of soil there. The price is decent and I got the Yelp discount for first time being there! The staff is very helpful. Will go back if I need more soil for my plants. read more

Awesome store, staff is always super helpful and friendly. They have a wide selection of products and if there is something they don't have in stock, they can call and order it for you! read more

Tim has been very helpful in getting my indoor garden started. He has a wealth of knowledge in planting from seed to harvest. GreenCoast will be my go to gardening spot from now on! read more

Walked in yesterday knowing nothing I left knowing it all. HAHA J/K But I do know what I am doing for my first grow (strawberries in a aeroponic setup). Guy was a great help showed me lowest and highest prices of product told me how they all work. I don't know how they are on prices. I was looking for a shop open after 5 and one stop shop. I got everything I needed I was even given a few tobacco seedlings we will see how those turn out. Thanks again _________(Forgot your name) read more

Terrible customer never can find what I'm looking for it takes too long to order something you guys have no stock at all

This is definitely the best hydro store in the area. I've been coming here since the start of my growing project. After going to other places and dealing with rude employees, it was a nice change to be able to deal with professionals that actually cared. Tim has been nothing but helpful since the first time I walked in, he always has a smile on his face and is ready to help. I usually have questions about what I have seen go wrong and he always has an honest opinion and try to figure out a solution that will best help your situation. No matter if your doing this for love on a small scale or just trying to figure out the biggest most efficient project he's always a great mind to bounce ideas off of. Definitely my go to spot. read more

Green Coast has knowledgable staff and a wide selection of products. Their prices beat out all of the other local hydroponics stores, and you don't have to worry about the quality of the equiptment you're buying. Go check out the store and you'll see for yourself. read more

Great place to get my soil and friendly staff. Make sure to check in to get your discount.

I love this place... These guys are so helpful. They really go out if there way to meet your needs. They rock...

I liked this place for the most part. I was new to the area and made this my primary store. In the last couple months, certain items aren't ordered enough time before they run out. There have been at least 3 occasions where they were out of dirt. A couple times they have run out of nutrients I need. Lately they have been out of Root Riots for about a month. As much as I want to support this store, it's hard when they don't stay stocked on the things I need and no one has ever offered an alternate solution (like giving two 250mL bottles for the price of one 500mL). The customer service is limited. I have found a new love 55 HYDROPONICS. They have a great vibe and cheaper nutrients. They have earned my business for sure. read more

Tim is the man! Anyone needing any assistance and looking to start a new garden or any info come and talk to Tim! He understand everything about growing and is extremely helpful no matter what part you are at! This place has all your growing needs and the help to get your grow started and keeping it staying healthy! read more

This place is pretty good, it's just they occationaly play their music loud and they dont really greet you. But hey that's just my opinion. I come here often for my garden needs. The price is ok. The staff has the knowledge when it comes to hydroponic and gardening. They take the time to help you out. They offered me bottled water and ice cold soda even when i wasn't planning on buying anything, which I'm sure they knew. Most of the staff seem passionate at what they do; I had a 20 minute conversation about pest and tomatoes once. I feel like a kid in a candy store when I come, they got everthing! You should come check this place out. read more

Impressive and well organized selection of items. A bit more expensive than other places and the staff was helpful but a little rude to me when I was in. Benefit of the doubt.. Just seemed like they didn't want to be there that day. read more

Marvin is the man! I needed a special order for an old mini split A/C filter and remote which I was told by 2 other reputable hydro stores that the items were available but in another warehouse and had to be searched according to their representatives. After 2 long months of calling in every week for a status I kept getting the run around. After losing hope, I decided to give this place 1 last shot and within 1 week Marvin was able to fulfill my order without any run-arounds and he even called me to tell me what's going on which other places had never called me once! read more

Tim, from Green Coast is awesome helping me and my fiancée with light hps and all the advices we need to collect and set up. He's great and awesome!!! :D read more

Place is huge and has all i need. Tim is awesome and went out of his way to help. Thanx GCHydro!

Today I bought two 5 ounce packages of gnatrol power for fungus gnat problems. when I got home and weighed them they only weighed 2.4 ounces and 2.9 ounces these were packaged in house. come on guys you can do better than that now I feel like I cannot trust you ot buy anything in your store that may have been tampered with ,not knowing if someone there is totally incompetent or you are trying to scam people . also I specifically asked if I got my 20% off all items the guy said yes when I looked on my receipt later I paid full price for both of these items. read more

Loveee it:) read more
