If you plan on expanding always buy 600W. Gave most my 400's away to patients. You should look into a dual 600w ballast that is dimmable. Lumatek makes a nice one that isn't to exspensive. You can use bulbs as low as 250w. Good Lu k.
My outdoor stain would be.sensi star. I use neem oil,bloodmeal, lime for the mt pests. I also piss around the borders of the garden. Deer don't like that much.
NICE thread I did the same thing but little bigger. I used happy frog, roots organic, Fox Farm OF, Bx pro mix. The strain is Sensi Star 10gals smart pots no nutes yet.
I got a Rev's Remedy that changes color like crazy love this stain little to no clipping nice dense nugs.
I got this stain from a guy that has a large grow op and had to swear that I would keep the genetics to myself. I think this strain came from a breeder in oregon. Not sure.
