Ended up going with hydroguard instead of hygrozyme... because it was much cheaper. I'm sure it will do the same job.

After stopping at the hardware store, I picked up the rest of what I needed plus a few extra lights.. four 32w 48" fluorescent tubes. Total of 11200 extra lumens ;].

The bulbs are 5100k spectrum... Which is this again? Flowering or Vegetative?

I'm hoping that I'm not giving them too much light right now between those and the hps light (which is 24" away from the seedlings)- but they seemed like they have been stretching so probably not.


I really do think I should cut the rockwool cubes in half... But I'm afraid that the roots have already grown way down.

Am I definitely going to have problems with the rockwool if I use slabs that big?

I wouldn't have used rockwool if I had done just a wee bit more research prior to using it.. Ill end up learning the hard way I guess.
