It would be nice if on a Saturday they could: 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. read more

Thank you for always making my visits a great experience and your hospitality! Can't wait for next time! read more

Big shop with a great selection. The service was very fast and helpful with cheap prices. I recommend this place to anyone!

This place is way overpriced and their inventory isn't even stock. I had to go to couple of other place to get what I need. I wouldn't recommend this place to anyone. Sorry but you guys need to step up your game. read more

The staff is excellent! Helpful since I approached them til loading the big sacks in my van. My only recommendation to the store owner is to post up prices on the items. I went to this store after reading that they have cheaper prices than other hydro stores. There was no info online, and I had to keep asking prices; you can't compare prices from one brand to the next too because you have to ask each time. In this area maybe the prices are cheap already but I've found other (farther) stores with less expensive same items. read more

This place is amazing! No judgmental staff who scoff cause you don't know everything, no crazy price mark up, just friendly knowledgeable people, and great selection at great prices. I go out of my way to come here over any other closer shop. Plus, the gave me a veteran/military discount when i showed my ID (not sure if they always offer This discount or just made an exception) Highly recommend NPK for all your hydro needs!!! read more

I'll be generous with a 4 star rating. I'd recommend knowing what you're looking for before you go in. My experience with one person working there who either didn't know about the product or was offering me an nonconsensual product upgrade along with a higher price almost left me feeling disappointed. Luckily, there was another person working there who was able to help me sort it out. I had entered prepared to buy more, but since that was the ONE thing I knew about, I wasn't about to ask about other items on my list without researching first so as to not be duped again. read more

This place was a great find. Very helpful and informative sales people that are eager to be at your assistance. They have a variety of products to suit any grower and what they need. I will definitely be back and letting people know about this shop read more

Fantastic store. Very knowledgeable staff that doesn't mind taking the time to walk you through the process. Very very informative. First time setting something up and they helped me with pots, nutrients, and even working out a basic schedule to start. I will be going here for all my hydroponic supplies. read more

Don't go here if you don't know what you're doing. I walked in and had a few questions and they weren't helpful. They basically ignored me until I bugged them enough to get my questions answered. I'd give them 1 star but they did help me. If I was more knowledgeable it would have probably been a different experience. read more

Rad dudes! Super nice and don't try and pressure you too buy other things. Gave my boy some stickers too ! Will definitely be back!

I've been trying to grow vegetables for the past year and I kept failing until I heard about this place. I learned it's not what a retail store can offer, it's the knowledge and hands on experience the employees provide. Any store can carry the same items but no one is going to walk you through the whole process. I mean, I didn't even know where to start. They walked me through step by step in order to succeed. I am already beginning to see results for the very first time. If you are looking for great quality products and an amazing staff that can help you every step of the way, come to NPK! They've been here for many years which is why they're so experienced in growing just about anything. Perfect for home grown fruits and vegetables and perfect if you're a teacher and would like to plant some stuff with students. Thank you guys for all that you do! See you soon. read more

I love this place! Always find what I need and the gentlemen who work here are all really cool guys! Check this place out if you have a chance. read more

I always come here. On point with everything. Any questions just ask and they have the right answer for you. I like how when their isn't a certain item they order it ASAP for me to be able to pick it up the next day. Super chill hydro crew here. Plus it's down my street so it's super convenient.!! The prices are great too! read more

Best prices best advice and best products keeping updated with the new need I says more go here and only here for my hydroponic needs!

Great group of guys always helpful when I come in. It's so cool that they have so many products in stock, one stop shop. Great prices!!! They also offer 5% off when you give them 5 stars on yelp so awesome considering prices are cheap already. I recommend it to all my buddies and now we don't go anywhere else. read more
