Yeah we’re still months away from last frost here DownEast but I’ve got 6 for me and 6 for Mrs Willd started in ProMix BX under a little 2-bulb T5 fixture. Never grown in buckets so can’t comment on that.
I typically dig 24-36"dia x 24" deep holes and fill 3:1 with ProMix:homemade compost. Side dress with compost every 2-3 weeks as mulch and feed.
