Growth & Observation Continue

The trays as replaced...

And after 1 hour!

Observations, Reactions, Additional Experiments to Date...
2/25: The covered growing material stays wet much longer than the uncovered. As a result, we decided to cover all trays, using opaque material (tin foil) on the previously uncovered trays (which complicates the grow light treatment a bit).
2/26: The growing material in the plastic trays stay wet longer than the paper, but both remain moist over night.
2/27: The first seedlings emerge: plum and beef steak tomatoes, basil in various paper vs. plastic, clear vs. opaque, warm vs. grow light conditions; and one mixed pepper (warm, paper, clear cover). No grape tomatoes or parsley are evident.
2/28: The germinated seedlings are hitting their respective covers, and those under opaque covers are yellow. All covers are removed to allow free growth.
3/1: Seedlings previously under opaque covers are now as green as the others. All the grape tomatoes germinated overnight and are already nearly the size of the other tomatoes. So far there are no parsley and no additional peppers. All seedlings, thus far, are dicots.
3/2: All seedlings grown without benefit of the grow light lean toward the window of the sill they are located on. Kallan thinks this is because they are growing toward the light. To test this we decide to replace the trays in the opposite orientation and see what happens. Kallan wants to watch, but forgets. In only 1 hour the seedlings have turned and are once again facing the window (See photos). We are beginning to think that we might have actually be able to watch it.
