Most of our seedlings we make sure to replant the baby at pretty much the same depth it was in its' original soil. Tomatoes are one of the few plants you can sink in deeper and they will root from the buried stem, creating a hearty, healthy plant! Most seedlings won't like that and may rot away in the part of the stem buried! These flats of bell pepper will go into the warmest part of the seed starting unit for a few days, on the bottom shelf right over the heat mats! This will help them root into their new homes. Then they will quickly move up and out, under lights on one of the tables. We also try to water all seedlings by gently soaking the soil, not the plant. Less moisture on the plants' leaves means less chance of fungal or bacterial blights and blotches. Humidity is not an issue, so we've never found the need for fans. We also run our hands over the seedlings regularly, not only for the great fragrance but we've read that it encourages better rooting and sturdier stems - something like a breeze might do in the garden. One flat of transplants - about five more to go to finish this flat of baby peppers! Then, there's a second flat of peppers, a flat of assorted herbs and two flats of tomatoes ready to transplant! It'll be a busy couple of days!
