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.
@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
