I'm able to work all sides of the bed so this plan actually sounds like a great idea. I plan on planting my indeterminate in the bed with twine and clip system from above and planting my determinate in 5g grow bags
I should be able to fit 8-10 ish me thinks, ima be supporing them from above via trellis/twine and clipps and will TRY to keep them tall ..... we'll see how it goes.
