Here are all my tomato seedlings hardening-off on the patio. The two left column areas are all cherry/small varieties, the last column area on the right contains the larger varieties of which I don’t have too many this year.
This is the first year I’ve used a grow light and the tomato seedlings are looking significantly healthier than in past years. I’ve also noticed some color differences in the leaves of plants which sat under the lights for this entire seedling season versus plants which had a bit more outside time under the sun.
Those are Carolina Jessamine in the terracotta tall planters, fyi.
Left town for 5 days to return to much larger plants. Clearly the investment in the grow lights were worth it. Here are 5-6 types of cherry tomatoes, a few larger varieties and some Japanese cucumbers toward the back. In the second photo are some younger seedlings, a variety of peppers, herbs and marigolds.
