ok, i have an ebb and flow. im doing 4 trays, 4 lights. 1 veg 3 flower. rotating every 3 weeks. nice sog.
i have no expierience with organic ferts. with the research ive done, ive learned you have to use the solution in 2 days once mixed!
this is what that means for me:
- i use 25gal of water per 3' tray. 15ml of bio flora/ 1 gal of water every 2 days! (thats 375ml/resavoir every 2 days) right?
- a 1 liter bottle is $30. thats 1.3 bottles every 2 days.

What am i Missing?

what kind of organic nutes can i use with a rockwool set up. id like to use the same water for a week or 3! just dose it up every now and again. Is this possible?
