This place is a hidden gem, everything is priced sooo low. Originally I was going to either go to homedepot or amazon for the stuff that I needed it, but good thing I stop by here, Tino was very supportive and educated me on all my plant needs for indoor and outdoor. I ended up saving 30% of my money shopping here then homedepot or amazon. I highly recommend this place. It's a bit hidden, but it's definitely a treasure worth searching for. Trust me on the pricing, just give them a chance. Support our local business and save money at the same time! Thanks again Tino! read more

This hidden gem is the best discovery, my new friend, Tino dropped so much knowledge on solving problems I'm having with different aphids, insects and caterpillars this year also on what would be the best nutrients they have available for my plants. They have such a great selection from different companies and all at great prices. I definitely recommend anybody with any type of garden to come here instead of any other big name company, you will definitely save money and the selection of items in inventory here is superior there is so much to choose from. Thank you once again Tino read more

The Hydro Source Hydroponics - Your one stop organic shop - Hydroponics Near Me - Covina, California

Stopped by here the other day to pick up some good soil and other supplies for growing a vegetable/hot pepper garden. The guy behind the counter was very knowledgeable and helpful. You'll get better quality soil here than you would at your typical hardware store, and it's not much more money. I'll be coming back in the future, and am just glad to have found a place where I can get answers and suggestions. read more

Awesome hydro shop in Covina. Great selection and very knowledgable staff ready to answer questions. Thanks guys!

These guys are dedicated to the industry. Always on point with the nutrients and c02. They have the best prices and all the name brands. You can even save a buck or two by buying their own brand equipment. Go to the Hydro Source and never be let down. A+ for equipment and A+ for service. Keep it up Tom and Simon! read more

They got everything you need to do it right. Prices are amazing.. walk outta feeling like you stole something they're so good. They can be kinda short with you at times.. but other than that great service. read more

The only place I go to and it's over 30 miles 1 way trip. They always have what I need and they beat everyone's price by far!! read more

Absolutely the best place to buy your equipment and nutes! They are affordable, knowledgeable, friendly and courteous - You won't have a bad experience with them.. They replaced an AC unit they sold me (Ideal-Air 36k BTU) that malfunctioned and they didn't even get credited back from the manufacturer - even though it was their horrible equipment and customer service that failed me and put my project back for over a month! Never purchase an Ideal-Air unit or anything else from them, you will be sorry if you do and I can promise that! read more

I drove all the way from Walnut fighting traffic to make it in time before 7pm I got here in time and the place is closed. I'm so piase off right now. read more

I'm pretty appalled at the treatment I received from the business owner of such a huge, lucrative store in Covina, Amazon, and Ebay too. 7/1/14 - Wanted to reorder an item that I previously ordered in Aug 2013, referred back to the purchase via email because the owner Keith Thai doesn't have any record of my purchase. Email from August shows he asked me to wire a deposit into his bank: 2 Bonsai Heros and a case of Xplode, plus shipping for $20 for a total of $1700. I made a Bofa deposit and even overpaid by $10; Keith offered to refund me. Never got an invoice or receipt. Fast forward to now, I wanted to make the same purchase, except now those 2 same items have a higher price "because the previous purchase price was a mistake." Wow, really, +$79 hike? No prob, I'll pay that. I looked back at the deposit slip and realized I paid $XXX for that case of Xplode that never came. Never even seen it, remember it, or sold it. Horrible of me to even pay for it and not remember to check for it, but mistakes happen. I didn't even realize it until now. Keith mentions because it has been nearly a year, he cannot compensate me for anything. Had it been 2 months, he would be able to do something, I understand. But help me out! Business owner to business owner, if someone paid me for goods, I need to deliver. Meet me half way! Do something so I won't feel so bad that I just threw away $XXX to this store! Foster a business relationship so we can continue to do business! What kind of a super store is this? I suggested different ways to resolve this. From giving me a deal on those 2 items I want, to checking his shipping department, to searching his records. I am here wondering, did it get shipped? Could it have gotten lost in the mail? Any records? NOTHING! Cannot give me the old deal,, cannot give me a discount, cannot give me the benefit of a doubt. NOT EVEN AN APOLOGY. Can't even redeem that $10 shipping credit he owes me. Now I can't even do business with this store anymore. I have to tell my customer I can't get him Bonsai Heros. The poor old guy is going to have to use his hands to cut until he develops arthritis. Going to double my money on buying Mega Millions today. And I'm over it. read more

We've come here a few times at first it was a great local spot to come get all Our hydro needs. But one day,I read previous reviews and they stated that they bought expired nutrients so we checks ones we had just bought, and sure enough... expired. Ok, fine, things like that could slip by. Today. We called because we desperately needed pots, I told him I'd be there, but he said he was leaving at 5. I made it to the store at 5:01 and everything was locked up tight. I guess they don't need the business. .. might be worth it to drive a little further for better customer service. If it were me, id at least given it 5:05... but thats just me. read more

Legit spot.... They literally got everything you need. At first I felt judged because they followed me like if I was going to steal something but the 4th time they saw me go in and spend over $400 so they hook me up with an account and 35% discount now I just walk in there like I own the place which feels good thanks guys read more

I love this place they got everything I need , plus! Dudes are very knowledgeable. So far so good I highly recommend ...

Horrible store. Price gauge unfriendly service. The Asian dude tommy doesn't know what he's talking about. Rude and always try to sell you things that are priced 25% higher than any other store. Do NOT buy from this store if you are not an aware shopper. They will take you to the cleaners. Online prices are better. read more

I paid a rush fee, and next day air. I had to call them to remind them of my order then they shipped it usps not next day. I called when I found this out. and got an attitude from the lady that worked there. then she tried to repeatedly give the wrong refund amount. less of course than it should have been. I had to argue to get the correct amount. read more

just started coming here. the main dude thats always there is super cool. thumbs up the this place so fare,

Super cool knowledgable guys. Love coming here. Brought my son here and they gave me cold water and an treat for him. Also gave me tips on how to set up my watering system. Very nice. read more

After trying lots of online hydro in US and Canada, I'm returning to THS and it's good to be back. Shopping from Canada, I felt I had to check out all options to bring down the bottom line, cause shipping costs obviously help to keep the bottom line high. Some shops are pretty good, but, none as consistently excellent as THS. Their selection, prices and service make international shipping worth it. Anyone who has done any online shopping for garden stuff in Canada knows what I mean. They answer emails in hrs, and again, my order is in the mail in less than 24hrs. Thanks again.......Merk. read more

My roommate told me about this place and although there are closer stores, I took the extra 10 minutes to check this one out. The guy who helped me appeared to be the owner. He was really patient and explained a lot to me. Wasn't trying to sell me on things I didn't need or up-sell. I will be shopping here in the future. read more

"This company is bullsh** They will give you one price on the web site then when you go to make your order they change the price on you. I talked to Keith and told him that it was wrong to give someone one price then when they say I'll take 2 and can I pick them up they say sure but now they are 300$ more each. DON'T deal with these scum bags. also if you buy something from them and it does not work like they said to bad we do not accept open box returns TOTAL BS " read more

Have done a few transactions with these guys via online,fast shipping the items i purchased work great.They go above and beyond to help you out if there is an issue with an order. I would defintely recommend these guys for your growing needs!!! read more

The good people at the hydro source do offer good discounts but beware most of their items are cheap or defective products they sold me a carbon filter and inline fan the filter was defective and got carbon dust all over the place and inside the fan which i tried everything and cannot get the dust out completley they did replace the cheaper carbon filter but as for the 190$ fan they said it was not their fault and would not exchange it so if you are looking for good deals you found the right place if you are looking for quality products and good customer service look somewhere else don't be fooled by the hopes of cheaper prices I was looking for the Walmart of hydro stores and instead found something equivalent to the dollar store by the way don't ask the girl at the desk anything because she knows nothing about hydro she will look something up on the Internet if you ask her about anything other than the price and I was asking what she recommended for powdery mildew since I didnt have luck with neem oil she sold me some pm wash I Thot it was to be diluted turns out u just pour strait into sprayer at 16$ for a 1 quart bottle is kind of expensive so I looked it up and turns out that this stuff is nothing but Ph ed water what a rip off avoid this Place if you don't have the money for defective and shady items read more
