It would burn you hands, yes a box fan would cool off a 1000w space heaters coils by about 20%. You cannot tell yourself because the temperature differences is like 400 degrees out of 2000 degrees but that is still a 20% reduction in heat loss. Plus a fan makes a room hotter anyway so over time in a sealed room it would get to a point that what your saying is true but not initially.
Yea i shot him, what he was claiming was missing so many key points and actually supported what I was saying while claiming it was a crock of shit and he knew it was b.s. Yea u get shot when you provide misleading "facts" on a discussion board.
So do you have anything that actually links a cooltube to reduced efficiency due to lowered temps within the bulb? I'm sure there will be some reduction in heat, but can you prove it to be detrimental under the circumstances in this thread? Logically, these things could be true with a big enough fan and a small enough bulb. But can it be proven within a grow enviroment with a conventional cooltube setup.
There' s so many differences in the glass that cool your lights and the glass that your bulb is made of. Anyone else care to explain?
The best thing I can do to prove it is say how I've grown under two 1100 watt output setting HPS lamps with glass and air cooled and two 750 watt output setting using the same lamps with no glass. My largest harvest on record came from the two 750 watt lamps.
So we've got something anecdotal. Not trying to insult you, but that's not really good enough to prove anything.
There's no explaining your processes. It gets interest, but doesn't tell much.
Lemme blow your mind real quick, no homo. If you are running a 450 cfm your using 110 watts of power for 12 hours and another 450 cfm fan for air exchange all day, A Dehumidifyer all day that uses 780 watts, Its actually cheaper to us a 1000 watt air conditioning unit to keep your room cool. By not running air exchange or exhaust fans you can also optimize CO2 use and don't have to worry as much about smell leakage. The AC is also a way more efficient dehumidifier and has a built in thermostat and will keep the humidity perfect for flowering if the correct size one is purchased. So why wouldn't you take your glass off if your not dealing with celling height restrictions and just use an ac? It saves you money anyway
Definitely more controls would be needed, just an observation of mine.
Good points and definitely should be taken into consideration. Foliar feeding should be done outside the room and isnt necessary if your plants are not having issue.
I'm going to add up all my venting equipment loads and see if that works out. Getting rid of the ducting would be convenient.
Most of the bulbs have warnings to only used them in enclosed fixtures. I've never had a bulb burst, but it only takes one to burn down the house.
CFL's are more likely to burn your house down than an hps in the correct hood. HPS has been around for so long, cfl's are still modern when it comes to heat displacement for the ballast. Check out this http://urbanlegends.about.com/od/business/ss/Cfl-Light-Bulbs-Fire-Hazard.htm
If that's the case, there should be a warning label about placement. CFL's seem to dim noticeably after a short period. The mercury in them was banned in other products, or required to have prominent warnings on them. They seem to have relaxed the health and safety rules when it comes to CFLs.
Everybody keeps dissing the Chinese. What's up with that?
