Kratky and plant height

[aclum]

As I'd mentioned in another thread, due to the CV restrictions here in CA, the gardeners haven't been able to come and do the usual spring cleanup for me. Right now I have plants about ready to transplant and the raised beds are a jungle of weeds! It could be a month or more until I can plant out.

Rather than potting up repeatedly or letting the plants get rootbound until the garden's ready, I've decided to give the Kratky passive hydroponic system a try. My plan is to eventually transplant the tomatoes into the raised bed soil.

Here's an interesting video showing the root growth in Kratky and the transplanting into soil:

Anyway, I'm thinking I may have to keep some of my plants in my 3.5 gallon Kratky buckets and I was wondering if anyone can tell me how tall Bradley, Mountain Gem, and Heidi plants get. Since they're semi-determinate, I'm hoping I can get by without trellising them. I'm thinking of maybe using a large cone cage for peppers and tomatoes (supposedly) secured through holes in the bucket lid might work.

Thanks for any info or opinions!
