Hi, I have obtained a box that I hope will be suitable for a grow ! I will seal the inside with mylar to make an inner skin, I might do the outside also as a form of insulation. It is 26inches by 26 inches and about 6.5 foot tall !!! I am looking forward to it but am planning on a bit more than my current lighting. I am thinking of about a 250 or 400 HID. I am considering a side ways SCOG (excuse my stupidity) Where i intend to use a screen around the sides and numerous CFL'S suspended in the middle of the box. I will attempt this in autumn cos the temps are high in my attic at this time of year ! Any suggestions with this planned grow are most welcome.
