Strain
Super easy to take care of. Very resilient to my inexperienced manhandling. I did a comparison with one plant growing in a spacebucket and another on a windowsill. Spacebucket plant had much more branches and a lot more buds. But because I did not give her any nutrients they stayed relatively small.
Lessons learned:
1. Start in the right size pot
2. Better to underwater than to overwater
3. Patience and moderation key to success (and not killing your plant)
4. Nutrients help a lot.
5. There is such a thing as too much light
6. Don't let your plants touch your lights! (cfl, close is ok but contact will mess it up)
In retrospect I probably won't use the spacebucket any more. For my consumption I can just have 2 tiny plants growing at all times and that's more than enough. Windowsill plant grew perfectly fine in a 2L pot with around 3-4 h of direct sunlight a day. And looks nice on top of that.
