Hi all

I have 4 seedlings growing and ive noticed that the roots are starting to come out of the bottom of the rock wool(4 inch blocks)and a a few out the sides.

Ive just got them in one of my trays at the moment.

With my hps light and iam feeding them on a weakened nuts solution.

The thing is a few of roots are going to end up in the light this is bad right?

What do i do next ive got a flood and drain system to set up(how do i do this?).but i dont seem to have covers for my plants!!



thanks cron

put some hydro clay ball over them or something
