I haven't worked out whether it is economical to buy 6 packs and pot them up into 4" pots but I think it must be. This is generally what I do in the fall with violas and snapdragons, as I feel it gives them a much better chance when I put them in the ground. Those six packs are usually a little root bound having been forced into flower with goodness knows what.
The netting is for a newly conceived project.
So the beds must be covered every evening to protect the other seedlings; lettuce, pak choi and arugula. That is what the netting is for; a frame work which will cover over the square foot bed and protect it , not just from this houdini but from the cabbage white butterflies. For now the the beds are covered with the frost covering, the trap is set again and we'll see what tomorrow brings.
