OK here goes.

We have 1x 125w

Then 5x20w (100w equiv) making a totall of 625w in totall. But only consumes 115w from the supply.

I also have a purple light thats used for fishtanks which has helped a fair bit.

So what ya think now lol

I usually grow vegatables in there (tomatoe , cucumber , e.t.c) and they dont half grow fast.
