This week I adjusted the grow cupboard.
I added the MH ballast set to 250watts, set to about 70cm+ height.
Heat is killing me i can reach 32c on days due to the MH and heat. RH at 45-50%
For now the critical orange punch is under performing. Besides the slow growth it kinda looks healthy.
I watered with GH micro 3ml for a 4l, added 1ml silica, and had to ph down. I'm also using the GH ph test liquid wich is roughly ph'd to 6
Thanx
