From what I understand is that with the Brick you need to addd some perlite or somthing to get some air in their. She suggested Hydroton rocks cuz you can reuse em. Another fellow told me 25% perlite and 75% coco In the brick style will do me fine as well. I went twith the pre ready bag to avoid adding perlite and other stuff. Regardless brick or Bag you have to add some dolomite lIme for a buffer to bring the coco up to 7ph. From what she says anyways.

My lights are Cfls perhaps I was pushing them but putting them 1 or 1.5 inches from the light at this small age. I have moved them down to atleat 2 to 3 inches.

My water is Ph 7 out of Tap I have been Ph downing it to about 6.5 to 6.8Ph I thought this was a smart moove but perhaps not?

Thanks
