  | Sputnick roped a friend into helping us get the sheet lumber home. The test fit framing is going well, floor and ceiling are cut. The rest will wait till tomorrow. Pic of one night's work and the chamber's final location in the bedroom. | ||

| Im going to be the next in line to say that most of this stuff is WAY over my head. But I am thouroughly enjoying reading it none the less. I was always told that the most light you can get is best. Why do you need the 'perfect' light combination? Why not just use a high wattage HPS with your 430w MH? | ||

| Gents (Europa + Sputnik) As a newbie on the verge of constructing his own cabinet, I am in-debted to the document of your progress! This is fantastic! I plan on building something much smaller and have a few questions... I noticed in your list of parts that you have some serious Wattage going on - do you have any guess on what your persistent power draw will be once you are up and running? Also, I was thinking of doing two plants (there's just little ole me and friends I feel are worthy  ) in a cabinet approximately 4ft L x 3ft W x 5ft H - is there substantial difference in light reflection than if I went square? also - I was planning on housing all of the hydro equipment inside of the room... does anyone have advice on my cabinet size? Am I going overboard for two plants?Not to hijack your thread will a flurry of questions - it's just that when you are this thorough, you incite (or excite) the rest of us!  All the best, cali-canuck | ||

| Hey there Stoned, glad you enjoyed it. Your right, the more light the better up to 80klux, if you can keep the heat under control. The reason I chose the 250W HPS rather than something larger is that it complemented the spectrum of the 400W MH. Together they produce high efficiency for photosynthesis and growth but also balanced color for normal plant morphology. The next step up in size for both lamps would have been too much heat for the size of my box and after my maryjane grow I'm gonna try something else, maybe roses. cali-canuck, glad to be of assistance and good luck with your cab. I calculate a total of 7.5 Amp at 110Vrms. Here's what's on the labels: HPS 3.9A, MH 2.5A, fans 2@45W, pump 23W, and air pumps 2@4.5W. If you use the mylar blankets on all surfaces, then there's no real benefit to going square or short for that matter. What kind of hydro rig will you be setting up in there? 3X4 is plenty big enough for 2 plants and almost any hydro I can think of. Blankets and fluoros are hung and the pots are in the tubs. I put a piece of plywood under the first (right) tub to get the water levels even. Last edited by Europa : 01-11-2003 at 05:50 PM. | ||

| The 400WMH, 250W HPS, 8X40W fluoros, total comes to 59,900Lux. F@#k, I was shooting for 60kLux. The Mrs. wearing shades, she thinks it's a bit bright for the bedroom.  | ||
