ppm growing range for plants
Hi, Ron

I want to try one of those. They also sell ones that you can attach dosing pumps to and automatically add nutrient solution and pH up or down as needed. I guess with enough money you sure could take a lot of the hard work out of keeping everything right.

Veg stage

First two weeks 600 up to 800
Next two weeks 800 on up to 1000 ppm
Last two weeks 1000 ppm

Flower stage

Around 1500 ppm all 8 weeks
