I currently have beefsteak tomatoes, zucchini and peppers that I've started from seeds on May 8th in a seed starting tray indoors.
They seem to be growing well under the light system I have setup.
At what point do I thin the plants? I have 2-3 plants per little hexagonal cell.
When do I move them to bigger containers? Thank you
I usually start thinning seedlings of herbs and vegetables, when they get their 'real' leaves. So I mean when they get more leaves after the first two (cotyledon) leaves.
Mine were in an egg carton tray for a month or so, from end of February til April. I left them on my stove top under the stove light. But I would take them outside for real sunlight and just water them lightly. They were about an inch tall in the egg carton, clearly ready to take off, before I transplanted them in my raised garden bed. The roots were very dynamic and well formed when I scooped them out of the tray with a spoon. I think you need to make sure they are strong enough to survive the transplant. I had planted about 4 seeds per “egg hole” so some of my plants, like my tomatoes, actually grew 4 plants in one. I just left them together and transplanted them like that. And some only grew the one or two seeds. The roots were too formed to separate them. I think it makes a stronger plant though. You have more chances of producing.
