Little update. I've moved 4 plants outside already, the two male OB's and 2 PP's. I've left the best plants inside, together with the seeds I started later. 4 of the PP's were in desperate need of re-potting already, so I placed them into 12 litre pots. They've gotten a small dose of all-round bio stimulator and some root stims for a little boost, the first set of lower leaves were starting to yellow a bit already. For the rest they're going just fine, I keep having to move the light up, the bigger ones grow at least a cm or 2 each day, they're hitting the 75 cm's already.
