Is growing Cannabis on the windowsill actually possible?!
Yes. Growing Cannabis is possible on your windowsill and you can even get some pretty frosty nugs. This size is limited... Although you can do some sort of horizontal stress training along the window or other techniques to capture all the natural sunlight.
a windowsill grow can be good for phenos you were going to kill... or clones you dont want. Its a way to get some quick quality nuggets. Have YOU ever grown on the window?? Give it a try next time you are thinking of tossing some genetics in the trash.
