First Fastberry and Bio-heaven test

The plants are growing very well even if the temperature gets really high sometimes. To help manage the thermal load i switched the light cycle to 6/2 cycles 3 times a day. The bio-heaven doesn't seem to have a noticeable impact on these plants right now it's way too soon to draw conclusions. I plan to start LST after the 5th node appears which is hope happens during early/mid week 3. I am already bending the leaves a little to bring more lights to the lower nodes. After stabilizing the temperature i took a look at a VPD chart ( http://i.imgur.com/HBnT439.png ) i noticed my humidity caused the leaf curling problem I raised the humidty to 70+% and try yo keep it there to keep the VPD below 9.
