dwc seedling

what is the best feed at the very start when i first put it in a 15 liter dwc appreciate your view

Seedlings should be fine till the cotyledon starts to yellow

then what after that thanks for the reply

Hey.. This is what I do with rockwool and RO water. Once the root pops out from the bottom of the rockwool, I put the plant in a micro dwc system with only 1/4 strength CalMag. Check out my Batch grow in my sig for more details.

Cheers,
