Time to plant for seedlings

OK...so I'm a little late on planting my seedlings due to other domestic obligations ...anyway, I have picked up some seedling trays from Amazon that are being used to start my seedlings. I tried using white grow cubes on my bell peppers in the past, which sprouted fine, but did not allow for enough oxygen to the roots and too much water causing rot. This time around I'm using peat moss. I have to pack each seed cell in the tray with peat moss, which should provide a good foundation for the roots. I am using a combination of rain water and FT water to sprout the seeds.  Hopefully, the greenhouse will provide enough light for stronger growing plants. I am growing two varieties of cucumbers, three different types of tomatoes, some heirloom, along with kale, lettuce, squash, etc. etc. etc. Once the sprouts are large enough, tomatoes will be placed in the media grow beds, along with the cucumbers while most of the rest will go into the DWC rafts once completed.
