They are somewhat hardy enough to deal with the transplant process. the reason why I did a tray set up like this, is that way I can plant a whole lot of seeds and I am noticing that some of these seedlings are doing better than others and that is rather normal. and the ones that are not doing well, I am going to go ahead and discard you really dont need all of them however if you do want to use them all, dont discard them but today I just plan on keeping 6 of them because that is what will fit in my hydroponic system.
