Growing the behindcorner NL

The seeds were germinated in a mini plant greenhouse, almost all of them had germinated in two days. After a week of continued growth, they were repotted to 100% organic coco soil and placed outside in the sunniest spot in the garden. They are on top of a small table so no snails can get to them. One of the Dark Devil plants did not germinate properly and from day 1 it has brown tips on the leaves. They are currently being watered by natural precipitation. The temperature is about 21 degrees during the day and about 10 degrees at night. Now they are two weeks old.
