re: Tom Bombodil's Malawi Gold & Western Winds Bumble in the Jungle
Yesterday evening I pulled my old axial fan I was using for room exhaust and replaced it with a modified Blizzard fan. The old fan was one of those 4" 120v giant PC-style fans, moved probably less than 50cfm. So even with the 1000w light air cooled and exhausted to another area, the cab temps in my 3' x 5' grow room were in the low 90s (°F)... too warm! The Blizzard fan had stopped working in its original form but once I got the plastic housing removed I found that the power cord had been crimped where it entered the plastic base. Removed everything except the fan itself, rewired the power cord to fix the crimp, and stripped out the gearbox that controlled the oscillation (don't need that anymore). After removing the 4" axial fan, I enlarged the exhaust hole in the grow cab to around 9" and mounted the 8" Blizzard fan so that the blades are just about flush with the cab bulkhead. Tested it during last nights light cycle and cab temps are stable @ 81°F, mission accomplished! The only thing about the Blizz is that its somewhat loud mounted directly to a stud as it is... I may be able to acoustically isolate it a little using foam and such. Also I'll need to keep an eye on the motor itself, it was quite warm this AM after almost 12 continuous hours on. But at least now I can close the door of the grow chamber, which means the rest of the bedroom is again available for domestic use, which makes Goldberry happy.
