Tomorrow or Wednesday, I want to start some French Dwarf Marigold seeds in 72 cell trays.
https://www.amazon.com/Pro-Hex-Tray-.../dp/B004NSD3CC Planting date could vary depending on the information provided in the replies here.
Last freeze/frost day is around 5 weeks from now, but this is Texas, so it could still freeze in earlier April.
My first question is: Can I grow them (1 Plant per cell) in the seed cells until plant out, or are they more like tomatoes and peppers that need to be potted up?
Question 2a: Do the seed cell trays need to have fluorescent lights an inch away like tomatoes need?
Question 2b: If not, there have been a lot of days with high temperatures in the 60s to 85 degrees lately. Could I just set them outside in the sun once they have germinated and bring them inside at night?
I am going to try this with 7 packs of French Marigold seeds to fight the RKN (Root Knot Nematodes) in our gardens. I think the transplants would have a better chance than planting seeds directly as I have always done.
A just for fun fact: French Dwarf Marigolds are the first flowers I ever planted. I had just turned 13 years old that day.
