Coco and LED questions

For whatever reason I only have access to animal grade coco so I must wash most salts out before using them in any kind of hydroponic system. My question is i've heard that a 3 part water to 1 part coco rinse is sufficient but I was wondering with this grade of coco would i benifit from having some kind of cleanser like a teaspoon of dawn.
Second question is in the opinion of the reader what kind of cfl bulbs are suffecient to supplement 2 137w led panels as far as spectrum and wattage for a 4'*4' space.Thanks

Hey,

I am not familiar with the Coco product.

However, I do use the same lighting as you in a 3' x 3' x 5' space. I have a Pro-Grow 260 (190w) and in bloom I supplement with 4 x 65w CFL, 2700k. 65w is actual draw.

This seems to be just right for heat purposes. Maybe you could go up a notch and go for 4 x 85w or even 4 x 120w. That's up to you.

You can check out my grow in my signature. I used to have 4 x 20w CFL just for heating purposes, why not heat with light... But I upgraded to the 4 x 65w.

I think it was in my second grow log that I added the 65w CFLs.

Anyway, Hope this helps.

P.S.
I also made a DIY post on making reflectors out of coat hangers and emerengency blankets (mylar for $2)
