Hand watering rockwool


Well-Known Member
I want to really get the roots going by air-pruning before putting my plant in the DWC, so I'm planning on hand watering with a weak nute solution. What strength shall I use? Do you think quarter strength and pH balanced will be ok? I might do a short test grow doing this and take it up to scrog height then take it down.

Start at 25-30% of the label recommended concentration for whatever stage of growth the plants are in. Don't forget that you will be running drain to waste while hand watering.
