That is interesting. I was under the impression the plants would need a
period of dark to complete their daily cycle. Have you done any
comparison in term of growth between having the plant under light 24h a
day, versus something more conventional like 14 or 16h? Are there any
crops that do *not* like 24h of lightning?

I also have some concern about transplanting plant that have been
exposed to such long "day". Wouldn't exposing the seedling to much
shorter (real) day after transplanting trigger bolting? I guess it
depends on the specific crop.
