I am so pleased with the quality and accuracy of the Growee doser. I grow ca**abis for medication and as a hobby. We all know growing plants can take a lot of time from your day especially when you like to have your setup dialed in like I do. Having this doser has made my life alot easier and growing cannabis is the most enjoyable its ever been !!!

I bought a 2 doser system with ph control. After I got it set up I had a few questions about value inputs and they cleared everything up straight away. Awesome customer service for what so far seems to be an invaluable product. Saves so much time and messing around. Real game changer in my opinion. Thanks for everything!

We were looking for freedom, freedom from making nutrients everyday. This product (Growee Combo) did that for us! Very easy setup, easy programming. Perfect for the hobby, home, or micro grows. Just what we were looking for.

I have 2 of these systems. One for veg and one for flower. I was able to take a one week cruise and felt comfortable letting the Growees do their thing while I was away. I came home to some beautiful plants with surprising growth and absolutely no nutrient burn or deficiencies!
