Been coming to Spectrum Hydro for all my grow needs and these guys are always friendly,…read moreknowledgeable, and willing to help. You can tell they have real experience growing plants and actually care about helping customers pick the right products instead of just selling stuff. Their FoxFarm prices are some of the best around, and they always seem to have what I need in stock. Great customer service, great selection, and a solid spot whether you're new to growing or experienced. Run and get your supplies from here!

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.

Adding photos to my earlier review. Parking was a bit tricky. It is behind the store, not adjacent…read moreto it as it may seem (that's another business's parking). (It will look like the store is closed from the street sidewalk.). Pass the storefront and take the next right (into a small street). Turn right again after another business's parking lot, then drive a quarter of a block towards the back of the store. Quite the industrial looking area back there. Walk into their warehouse-like store. The cashier station and wide variety of products photos are taken from that entrance's vantage point. They'll even help you load your vehicle with your supplies! I'm still amazed at how eager they were to share ideas-because I do not have a green thumb at all.

It would be nice if on a Saturday they could:…read more 1. Be open earlier than noon. Some of us need to get stuff done during normal business hours. 2. Open on time. If you are going to take your time opening, don't take my time as well. 3. Pay your taxes. I'm all for cash sales, but you should still be charging sales tax. Westminster is already broke because of this crap. 4. Put your actual business name on the front door. Wow. What a concept. 5. Answer the phone or check your voice mail. Welcome to the 90's.

Saw this hydroponic store off the 22 freeway so I decided to stop by and check it out. Glad that I…read moredid because compare to the other hydro I got my root excelurator for only 150 for a liter instead of 170-180! Also grab a couple other product like terpinator and cal mag. So much cheaper than every hydro I've gone to. They even help me grab the nutrients and take it to my car.. friendly and helpful. The nutrients they have are mostly big bottles but the price is awesome. Coming back for sure

I've been in the industry for over a decade now and Mr nice guys nutrients has been the base and…read morecore of all my places for over half of that. This industry is continually changing, prices spike and fall, products continue to improve as does your competitors. If you don't learn how to cut the fat out, you have zero chance for it to be lucrative. And with all the things I already must adapt to, it's nice to know that I am consistently saving money every time I mix my feed while my competition keeps burning away at his profit margin! Thank you Mr nice guys hydroponics, I appreciate your work and integrity looking out for the small guys- Billy

Their…read morewebsite said 5 so I figured I'd call to verify before driving over and outgoing message said 7pm! I flew over before 5pm and the door said 4, vinyl window sticker said 5. I guess 4pm was the one they're going with.... I opened Yelp to see 4pm also. I hadn't thought to check Yelp earlier since it's usually hit or miss on accuracy. I understand not taking the vinyl 5pm off the window since the 4pm is a foot and a half away and Covid has thrown most businesses into crazy temporary hours but website and outgoing answering machine?! I can change the outgoing message in less than 5 minutes.
