I have upgraded the cabinet since last update, and i have plans to do a complete rebuild, given what i have learned from growing in this thing over time. I would like to improve airflow to keep temps down. The new cool tube helps a lot, but it's also a higher wattage light. It currently runs anywhere from 75-80F, but during the summer months it can run up to 90F.
I changed the light to a 250W HPS with a cool tube a while back.
I took out the carbon filter and the fan, and put a 6 inch duct fan on instead, so i could raise the light to the top of the cabinet. The exhaust currently gets reduced down to 4 inches and sent out the pre-existing 4 inch hole.
Rebuild Plans:
1) Installing a white wood board on the back of the bottom chamber, like i have in the top chamber, so that i can mount the timer and a thermometer and all other things associated with veg, in the veg chamber. If i want to access that stuff currently, i have to wait until the top chamber lights are on, or else risk messing up my dark cycle.
2) Cut a 6 inch hole on the top corner so that my exhaust airflow is improved. The old hole can be mostly covered by a new white board, but i can also use the hole to run the ballast wires out (step 3)
3) Mount the new digital ballast on the outside, back, of the cabinet.
4) Cut a new 6 inch hole for the intake in the bottom chamber and run a 230 CFM muffin fan. I'll only have one intake, instead of the current two 4-inch intakes. The other hole will be covered by the board i install for step one.
5) Cover the outside back with that silver insulation stuff you can buy at your local big box store to help cover up the previous holes, and to help block the bright light from any thermo imagining.
I'll put up some pics when done.
