Florida, I took your advice regarding raising the plants toward the lights. It's a temporary measure, but I simply placed a piece of white masonite on an upturned bucket and placed the plants directly under the glass separating the lights from the greenhouse-area. It has only been one 18 hour light-cycle and I see a definite improvement already. The top of the tallest plant is now approximately 10 inches from the MH. The bottom of the glass panel feels completely cool to the touch, so I think my heat-extraction is working a treat! As a result, I have no fear of the plants even growing to touch the glass in the event that I am unable to adjust the height of the shelf. Will definitely make a more elegant plan for raising/lowering the shelf than the bucket as soon as more time is available, he he. I also still want to waterproof the floor and cover the walls in reflective material. Right now there is income-generating work at hand and something has to pay for all these new toys!

nice man. sounds like you have some bud in your future.

my friend made something similar to you light box. its a bank of cfl's in and enclosed box with a peice of glass on the bottom. it works great and the plants can be touching the glass it wont burn them.

After two 18 hour photoperiods I have now noticed that none of the plants had grown any taller (easy to check with the plants sitting right underneath the glass pane - probably no more than 6 inches from the light), however there is some serious action going on lower down! I will work on a more elegant method for raising or lowering the plant-base when I get some free time.

By the way, can anyone tell me how long it will take those two cheeky 4 inch high flowering ladies to revert at 18 hours of MH loving per day.

thats exactly what you want. instead of growing tall trees your gonna have short bushes.

I'm having to take a quick business-related scouting trip to Durban. I think my first stop will have to be at the very first dealer I find that sells Durban-poison. It is a classic local pure sativa-strain, with a reputation for a stunning buz. If I'm lucky, 1/4 of the baggy will be seeds!
