It's hard to coordinate something like this! I'm just happy I'm able to try bucket growing, it's something I haven't done before, and the challenge will probably teach me something. 5 gallons is pretty big I think, but if somebody wants to play along with a massive container, why not? They just can't get win any yield prizes (assuming there are any). Even just the exposure is good, plus the upvotes, anything at the end would just be a bonus to get more people excited to (playfully) compete. I do like the idea of a running contest (over several months), to allow more people to get involved. Maybe each time somebody competes, they get a mention (permanently) on the board. Maybe there's a list for anyone who finishes, and another for anyone who competes for best yield. Maybe the board clears every year or so. Maybe when you complete a bucket plant, your post gets mentioned and recorded on the running board. That's like a small prize in itself because your post and profile will get hits. Just ideas :) You're already doing a great job.
