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
@JUNGLE_B4RNS, those won't be the best sadly, i ripped a cotyledon on the n°1 and the other one has suffered root damage during transplant. It's still a pretty fair comparaison but the fastberries will stay behind i think
