She's growing so fast. I was just watering the rockwool cube whenever it dried out but I put it in the net pot today and covered it in LECA clay pellets. I topped her yesterday as well. PH and ppm look good. I'm just going to plug in the dripper every once in a while until the roots start growing through the net pot. I don't want the rock wool to be submerged. The top is covered with clay now so shouldn't be susceptible to mold from the light reaching it.
Looking at my last grow (CBD Blue Shark / Wedding Cake) I didn't provide enough light or nutrients at the start and wasn't able to top until week 6. Growing in peat/rockwool instead of paper towel/soil, adding nutrients right away, and using the HID grow light from the start instead of a smaller cloning light seem to have made a big difference.
