Rolling right along with a couple harvests under the belt for the current grow.
I just finished setting up an identical DWC that will get 6 new varieties from a mesclun mix I have germinated. I'll get some pics up soon.
I have noticed a need to add some PH down over the past week. It must be from the rockwool as I stayed pretty balanced in the
ebb and flow with root riot plugs. Just an observation, no worries the plants are growing great.
DWC is definitely the way to go for lettuce...so very simple.
