One of the castaway's didn't sink after 24hours, and didn't pop after 48 in some moist soil. Every thing else was just fine. I think my cheapo amazon goose neck grow light I used caused them to grow leggy. I played around with using a blue fluorescent and just leaving them outside because it's not freezing here. I have to wait until the tent is empty as I have one that's almost done with flowering. Hopefully I can bump these along with cheap growlights, and outside time for about 2-3 weeks
