It was a suggestion by friend who grows a lot is all. Im not stuck on it by any meansDon't mix soil and coco. No idea why you'd change your grow medium if you've grown before...
I hope you have adequate A/C for all of those lights. Is it a sealed room? What strain are you running? Do not mix coco and soil, coco causes more problems than any benefit it.
Not 100% sealed but close. Good to know about the coco will stick to soil first go. I do have air intake fans and exhaust for all the lights
That's a great point. Updog is actually more important than CalMag. Don't start your grow yet unless you already have some.And make sure you stock up on a lot of updog. Some people like the powder but I prefer the gel, either way you’re going to want to use quality updog throughout your grow.
