First Fastberry and Bio-heaven test

Started off in root riots in a small propragator, and tranplanted to their final pots directly. (11L Smarpot filled with biobizz all-mix) Soil was enriched with elycitor from Biotechnology The goal of this grow (and my green crack one) is to compare a plant fed with bio-heaven and another one without to see if this expensive nutrient is worth it.

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.

Temperature control is pretty complicated without automation and the plants do suffer a bit from it but they are a little late. It is too soon to start the lst, the number 1 doesn't have long enough inter nodes and booth need to grow out a bit.

Pistils are appearing (day 22-23), i added the screen right before strectch (day 25). The Bio-Heaven is starting to show usefulness, I'm very happy about this. Nonetheless all the plants look very healthy (lacking a bit of humidity but still nice) I decided not to LST those plants to see their natural developement, which i don't quite like because it requires lots of space i think a small LST like on my other grow is the way to go in confined grow rooms
