Is this broccoli already too leggy?
In my ongoing quest to grow broccoli, I started some seeds indoors last week. I've been growing them in an enclosed porch that has three windows on the east and one window on the south; they get direct morning light only until about 11 AM. I have not been using artificial lights, but I do have a space heater in the room that keeps the temperature between 66 and 75 or so.
The seeds all germinated by day 6 and I was feeling pretty smug about them, but now I am reading that seedlings need a lot of direct light and am wondering if they are too leggy already. It's now day 8 and the tallest seedlings are maybe 2 inches. Yesterday I started putting them out for a couple of hours in the early afternoon to catch little more sun, in hopes of encouraging their proper growth. (Outdoor temps here have been in the 60s.)
The seedling all still have just the original leaves that I believe are called cotyledons. Do you think they're on track to develop their true leaves and grow properly or do they look too spindly to survive? My intention was to wait for the true leaves, then cut all but one plant in each pot.
