They are growing fine.
We try to leave plant no.1 to grow as it is and torture plant no.2 so we can compare the two methods.
Also tried fimming on no.2, but I'm not sure if it was successful, because I think it is still growing in one direction. Any suggestion is appreciated.
For two days in the middle of the week, we put the lights up to about 50 cm, so the plants can increase some hight and then put them back to there originial place. Now at the and of the week we put an additional 2700K light into the tent, we'll see how they're liking it.
