Ok so a box isn't necessary. Great news!

Will try to get on the reflector and fan today. Will prolly need some help figuring out how to set up the reflector... hopefully mylan or some other cheap reflective material (suggestions?) can be found at Home Depot.

So yea, if the reflector does not work out so well, I will still have 5700 lumens on one plant. This will hopefully be enough for flowering, yes?

Anyone care to propose a timeline?
