    The employees at Spectrum store in West Covina Mall are not accommodating at all. Very unreasonable and unprofessional!!!

    I'm sad to have just found this place only for it to be closing May 9, 2025…read more Gardening is an expensive hobby, especially if you buy your supplies from the local nursery! I just paid $36 for a bag of Fox Farms Ocean Forest potting soil at the local Flora Grubbs nursery in MDR. Later that night, I'm on Amazon researching and see someone mention the same bag of soil will be a fraction of the price at your local hydroponics store. Hopped on Yelp and found GreenCoast LAX! Stopped by the next day and my goodness... Fox Farms Ocean Forest for $11.50!!!!! Fox Farms Happy Frog for $12.50! These are the prices we should be paying for this soil!!! A guy at the front desk was helpful and answered all of our questions. If I don't find another local hydroponics store with similar prices, I will be visiting their Long Beach location! Overjoyed with my purchase. Great product at a great price.

    My experience in comparison to these other reviews was lackluster. I arrive around 4pm, there were…read moreabout 3 young guys at the counter, 2 were helping other customers. I approach the counter and I let him know I bought my first clone and that I'm a complete newbie, I still didn't get a warm welcome. After a few seconds of awkward silence, I let him know I was looking for a PH kit to test the soil for my plant. He takes out the General Hydroponics brand and sets it on the counter. He never gave me any explanations, didn't try to help me compare brands, didn't even tell me why that's the one I should purchase. I then ask him does he have a digital option, he then takes out 2. One was the Hanna instrument I purchased and the second was blue lab I believe for $100. I don't feel comfortable spending my money on things and idk what I'm really getting, I didn't know about there refund policy, if there are warranties, Zilch! As I'm waiting to pay the $52 since it was difficult for me to get change back, I notice they have gorilla grow tents and I was happy for a moment because that's also what I needed a grow tent, I let him know you're losing out on money you should be trying to up-sale me. Instead he kept recommending me to buy nutrients for my clone, when I already purchased some when I planted it. He just asked if I wanted anything else and yes I did, but not with that type of customer service, then wanted to know if I had a membership. I told him no, he didn't bother to see if I wanted one. I had to tell him I would like to make one and gave him my information. I ended up looking around on my own, after the fact and saw a lot of interesting things, I even wanted to go back to the counter to buy some products but told myself my money is better off somewhere else. Once I got home and I start looking at all the manuals and instructions. I find out both PH testers are for water only....when I told him I needed it for my soil. Now I've wasted $52 and didn't get what I truly needed and it's all because someone was careless at a job they get paid for! As a first time grower, in the learning process this was a really bad experience for me. I really hope other hydroponic locations do not carry themselves this way, as far the future I don't see myself returning and I can not recommend this location to anyone.

    I drove there to purchase Fox Farms Potting Soil and was running a few minutes late. I called them…read moreto tell them what I wanted and I would arrive (per my Navi) 2 minutes after they closed. They were so nice! They waited for me, and when I got there they had my order ready to go. They also loaded it all in my trunk!!! What company could do anything better than them! I highly recommend!!! PS For some reason Yelp is not also letting me select 'Value' but I wanted to mention that their price was better than anyone's around!

    My friend who is a gardener/landscaper told me to look for a hydroponics store, so we could find…read moresome starter trays since we had trouble finding it elsewhere. I had to look up incubator/propagator everywhere, and I think for Home Depot, they sell them in bulk and have to be ordered for pick-up in store. Anyway, we went to Walmart and the Dollar Tree, and I don't think they had it. This store has a little bit of everything from 99.9% alcohol, 30% vinegar, fertilizers, seeds, fans, dehumidifiers, pruners, etc. They also have Clonex in 1 qt, 1 gallon, and 5 gallons, as well as in mist form. It has a distinct smell, but the employee was friendly and chill. We have been using the supplies we got here to clone some plumbagos and coffee berry plants. The goal is to also try to clip some Mexican elderberries, too. There is a lot of moisture, though, so definitely make sure to vent properly. My friend got me some shears here, and I believe they are $7. I haven't used them yet, but I will update once I do, and hopefully we will be back because he said some of the stuff is decently priced.
