I agree; unless you have the means and desire to test for relative levels of your various fertilizer components (about $30-$50 per sample, per compound, plus usually a 2 week turnaround time at a water lab) once every couple weeks, you are shooting yourself in the foot by not changing out the res. As PHJ noted, your plants will use ferts at different rates, and you have no way of knowing WHAT exactly is making up your xxx ppm number... Save the headaches! It's easy!
stinkyattic Reviewed by stinkyattic on . Most possiple plants under 2000 watts. so I want to put as many potted plants under lights using DWC methods. Should I stick with individual buckets or should I got to multi potted containers such as rubbermaids? I have 17 air hoses with air stones that I can run. What is my best bet at running a good DWC setup, 17 individual buckets or like 12 individual and a few rubbermaids that can hold 4 each? Rating: 5
