I purchased multiple towers to go outside, while I keep two inside.  I planted most of my seedlings in the rock wool by the seed company directives on timing.  Unfortunately, it appears my seeds didn't want to follow that timing and accelerated their growth.  Now I have multiple tomato, pepper and eggplant seedlings  taking off in the germination trays and I can't possibly put them outside (safely) until 6 weeks from now.  It would be a crime to kill all these beautiful plants because I now have nowhere to place them- they can't go in the inside towers because I've already discovered what a disaster that can be!  Has anyone had this problem and/or has a solution?  It would be very simple to repot them into bigger containers if I was using dirt but they are trapped in their little cubes and I don't know how to let them grow without any further support medium.
