Beautiful! Are you using ebb and flow? I'm trying hydroponics again this year. So far I'm happy with the results too.

Yes, Hal, this is an ebb and flow system. I'm amazed at how often I have to replenish the water in the holding tank (almost daily) now that the plants are quite large. It is sure nice to have the tomatoes though. Good luck with your setup. Is it ebb and flow as well? Jim

Great looking plants, they looks very healthy..I am also growing tom's in an Ebb and flow table, This is my first time growing in an ebb and flow system. My question for you is, did you cover your roots or did you just let them sit in the bottom of the tray...I have not covered mine and they seem to be turning a bit green. is this ok? You can see my set up a few posts down from your "new grow box with pics" my plants are about 12inches now and growing FAST. Also, At what point did you go to a bloom fertilizer?

I'm not sure what you mean by "cover your roots". I started the plants as seedlings in regular soil six packs, then carefully washed out the soil when I transplanted them into the clay rock (just like yours). I had some rocks in the pots, layed in the extensive roots and gently added more rock to cover all the roots.

I let the plants get pretty large (3 feet tall) and gradually transitioned them to more bloom than the original mix called for. I still occasionally add a dropperful of Schultz liquid 14-14-14 to the storage tank as I add more water, but am generally using mostly the liquid bloom formulation I've got, with smaller amounts of growth and micronutrient formulas.

I read and saw a picture of algae getting on roots (which turned them green), and the person responding said they didn't think that it was anything to be concerned about. See the NFT algae issues thread and picture just below your thread on the new grow box. That would be my guess about roots turning green. Keep posting pics to let us see how it is going. All the best, Jim

Here is a picture of a few tomatoes I picked today from the hydroponic setup in the greenhouse. Amazing! Jim
