Well who would have thought a routine hospital check-up could turn into a calamity. My arm ended up the size of my thigh and all construction was postponed for a week until I could feel it again.
The Growbox
(55cm W x 100cm L x 110cm H) – wooden frame with screw'd n glued plywood panels.
2 x 125W CFL with reflectors – these are fitted with the warm spectrum for flowering stage. I may purchase some cool veg'ing bulbs if finances allow but went with the warmer spectrum in the hope of taking a couple of plants to completion indoors later on. There are also 4 x 30W cool CFLs that will help with the brief vegging stage.
Venting, light baffled open base vent, with a single ultra quiet 12V PC fan at the top for heat extraction. Later this exhaust vent will either be used in combination with a filter/fan assembly into the room or preferably vented directly outside.

I will add a small but decent circulation fan as well as I want these plants to develop strong stems from the outset so they won't flop at the first storm they encounter outdoors.
After a dry run with all the lights on it seems to top out at 28degC so should be perfect for growing... still have to finish making the door but will be starting off some beans tomorrow.
