What kind of yield do you get from one bucket? And when do you plant them? sounds like it would work better than a tower, even though you would probably need many buckets.
I generally get 2-4 lbs. from each bucket depending on type Russet, Yukon Gold, Red, etc. You can plant them anytime you like. I grow them all year indoors and outside. I've harvested the current batch as I won't be able to water them while out of town. I'll plant another 7-8 buckets when I get back from traveling for the holidays. I try to plant 2 buckets 3 weeks apart to ensure a steady supply.
