I started tent growing in my latest garden, and although the efficiency of a 600w parabolic in a 1.2m2
tent has amazed me, I've struggled to
work out an efficient and effective way of getting an ideal HPS/MH mix.
I liked Budelaire's shade but I wanted to get an even spread and use two HPS with a MH in the middle. A DR240w would allow two parabolics, with space in the middle for a MH fixture. A quick bit of maths showed I could use two parabolic kits to make a 220cm long gondola, using all 16 panels and both fittings - efficient construction, but would it hang, or crumple into a twisted mess?
Coming up with a bracing solution took a while, but I settled on a 1000mm x 500mm sheet of 0.5mm aluminium: strong, lightweight and reflective. Holed drilled in four of the parabolic panels, and the aluminium sheet, everyting bolted together using parabolic kit screws.
Kit for basic gondola: Two 100cm parabolic kits (£70/pair, new on ebay) + 1000x500x0.5mm aluminium sheet (£7).
