@Bucket_Buds, Yeah, I was also looking at those types of trashcans before I finally said f*ck it and just got a tent instead. Smart trick with the interlocking trashcans. Way to go!
@love_2_grow, Yeah! We first had a bucket made of 4 normal black buckets, which gave it a bit of a unique hourglass shape. Now we are rocking 2 90l trashcans stacked on top of each other! By taping/gluing the outer rime of the lid to the top bucket they even lock onto each other!
@Bucket_Buds, Sweet! Are you growing in a space bucket? I almost went the bucket route myself but could never find any buckets that I was really happy with so eventually just bought a tent :D
