Dutch,
I just started my first grow I am running the whole Aptus line with Heavy16 as my base in coco.
I am looking to change to FloraNova as my base. I also am thinking of trying the Vermi Fire/coco mix....what would be the percentage.
What is the optimal temp you like to run your canopy at for light adjustment purposes.
Any advice would be much appreciated...thank you very much for your time.
