Hey everyone iv decided to start some plants from seed this year and i seem to have germinated a bit to many. I have 94 total planted in cells that are 1.5" square by 2.25" deep. I want to keep as many as I can till last frost so I can move them to a greenhouse. I have little space so I was wondering if anyone could give my any advice on how long I can leave my plants in the cells before having to put them in pots.I also plan to pluck out all the weak plants.
