Growing seedlings in planter boxes?

[maxjohnson]

I'm starting 90 seeds this time. I think it's daunting for to be transplanting every single one of them into individual red cups and labeling them all.

I'm thinking just buying small rectangular planter boxes and transplant 6 seedlings in each until they are big enough to put in raised beds.

Probably will cost a bit, but I'm lazy. I don't care if I damage the roots a bit during the transplant.

A cheaper solution are those aluminum foil pans, somehow I'm not a fan of disposable aluminum.
