I have an awful time getting veggies to produce, so this year I decided to start them 3 months early instead of two. I have transferred half my tomato seedlings into cans with the bottom cut out, and sitting in a tray of soil, and when they grew taller, added root tone to the stem and stacked cups with more soil. The other half i just used plastic cups, as that's what I had. They were a mix variety of tomatoes with all the same soil, light, heat, water, EXCEPT for the cans. I think it very curious that the tomatoes in cans on the left are 24" from bottom of can to tips, and those with just plastic cups are only 13". Think it's the metal from the cans? Extra heat from the cans? (BTW, squash had the same reaction)
