Kept promises

They said the truth spoke the truth and came through with everything I needed and didn't let me down life time customer here from now on.

Good price in a timely fashion. Thank you

I have not yet received

I will not let this judge my rating completely bc I get it right now with these times but I’m hoping to receive it within 10 days though.

Gorilla Grow Tent Grow Room Net Trellis

Scorpion led

Awesome Light fast shipping

Great product - as expected

As expected, the trellis lives up.

I would like to see the flexibility for the use in other tents and more trellis holes - twice as many.

The negative is the shipping cost and delivery time to SE. Note ships out Within 24 hours to DHL >train across US >local USPS> ... any way too long for when you need it.

Rating: 4 out 5 flowers


Love this for its antifungal.

Much appreciated

Always great and ships quickly!

A Monkey Fan That Works

First, great team. My first fan had a problem and they replaced it. The new fan is great. And it actually has an "expected fan life" chart on the side that tells you how long you can expect the fan to last depending on how many hour of operaton.

Humboldt countys own

They have the best products out there. After using a different brand for years, I tried HCO after a friend told me about them. After 4 harvests my plants are healthier, bigger and tastier. Great product, the whole line of products is superior, in my opinion, to anything else ou there.
