I have formula flora grow nutrients, and I have a 396 gallon water pump. I was wondering how big my res should be and how much water should I have in my res?!?
Ill be growing in two 4 foot pvc pipes, with 4 holes in each pipe. haven't started growing yet, trying to get everything figured out before hand. Going to feed a hose at one end and let it drip back in the res on the other end.
As a general rule, I was taught a minimum of 7gal/plant is best. You'll have less ph drift & easier to manage. Much depends on size of pots, but you'll be safe with that #.
