I'm shocked by how close you can put a 150W winged reflector above the plant, looks like 6"-12"? What's the temps?

If you look in the ICMAG'S OFFICIAL ~DIY~ LINK-O-RAMA
you can find threads on DIY cooltube's, (I made the bake a round from those instructions there). And I think there is a thread to make your ballast remote too. To search, it's a little easier to google the things you want and follow it with icmag, the boards search option isn't that good.But all the info you need is right here.

I've had to remove my 150w HPS from my cab. The heat was just too much, always 90 -95 F
My plant suffered heat damage, all the fans went crisp yellow along with some sugarleaves and lost a good two handful of leaves in flower.. damn. Whats funny is I didn't notice till it was getting really bad! The yellow light of an HPS hides yellowing leaves.
I put back my 125watt cfl i was using in veg, its one of those giant cfl bulbs with a ballast on it and have 4 23w cfl hanging the left and right off the plant.
Have to buy a inline vortex fan with a few hundred cfm and probably a carbon filter with it to boot. But thats gonna be another 250 dollars.

You're gonna need a fan to move air out regardless. I made my first one work with a 115v (100 cfm) case fan I found on Amazon and a DIY scrubber. A piece of glass between the light and the plant would also help to get you to a low enough temp to make it work. That being said, the second Cab I built had a Soler & Palau TD-100X In-line Exhaust Fan and a Phresh air filter and I still lost a crop to heat. The DIY cool tube was a lifesaver. Long story short; A Cab with a 150 and a hole in the roof won't cut it from my experience. Read more and show us some pics.

My cab is only 46 cubic feet. If I get a 400 cfm fan it would clear the air out 9 times a minute. That should be good enough right?
I think when I do get a 600/1000 watt hps or something, I'll definitely buy one that can be air cooled.
I've gonna use my 150watt HPS now for vegging clones. It seems to work great and much better growth then flourescent or cfl!
I have my clones about 5 or 6 inches from the 150watt hps bulb with a fan blowing across in an open room. It works great, plants are alive and not burning.

Folks often forget to consider where their box/tent is located when they try to cool it down. No matter how much air thru-put you have, the inside will always be warmer then the ambient temperature of the space in which its located. If you keep your room at 78 degrees, which is obviously pretty close to 80, it really doesn't take much for your inside temps to jump 10 degrees to 90. Without active cooling, the best you can do is to keep your room as cool as possible while having the exhaust vent at the very top of your cabinet and the intake at the very bottom.
JohnKimble: "In the winter I'll drop the ducting to the floor for bonus heat"
So I did this early on in my growing. Of course the timing worked out so that was exactly when my plants were coming into bloom. Within a week the entire house wreaked like skunk. It happened slowly, so we never realized just how bad it was. My wife complained and I promised her I would figure something out. I dragged my feet getting it done until one day the doorbell rang. It was the AC maintenance guys here to do the fall filter changes. As soon as they thought I was out of ear shot, one said to the other "oh my god, it smells like they have a suitcase full of fresh pot open on a bed somewhere" then they started to laugh their asses off. My wife heard them as well. Needless to say, that evening I built my very first carbon filter.
Cool story bro.
And I'll second that placement issue. My small cab is in a walk-in closet. Although I have a computer fan going inside the box, cool fresh air intake coming from under the house, and a Vortex in-line exhausting out the top and into another room, heat has always been my main issue.
Even with the central air keeping the house in the 70's, that closet just retains the heat. Once hot, I'm screwed. I have to leave the door open a lot. Which I prefer not to for security as that Vortex makes a racket as well as that dim light coming out of the closet at night is weird looking. Even though I have made the cab almost completely light-proof, there still is a glow coming from it.

hi aki .I think it depends.
how much soil is going to be in the pot?
also I guess it depends how long it takes to trigger the auto .
I think if you toss a normal 8 week strain into fresh soil in clone form and you should be fine to go all 8 weeks with nothing in a good sized pot but you can always buy a simple fertilizer line to boost if you want or make some compst tea every now and again .what I leanred is the less you put in the easier to is to harvest good shit with less problems. hope that helps.

Hey all, i'm planning on growing in a 16''x24''x20'' tent using this light. Any recommendations on if i should be using any supplementary lights, what strains would grow best, how many plants i should aim for, etc? This is my first grow and i've done a lot of independent research but you guys seem to know what your talking about when it comes to 150w light grows. Cheers mates

Hy, whatta ya know? Same scenerio as me, away for a while & have new plans although mine are upscaling rather than downsizing. I remember you from my grow diary. I just added a couple posts with new plans to it. You have a thread with your plans? If not, let me know when you do & I'll follow along. I gave up on speed controllers too.
hello
my 150 watts hps keeps on clubbing in the club
got some duckcrosses going on .
and all automatics at the moment .
just because the tempertures are a bit low overhere .
about 17 degrees celsius 62.2 fahrenheit .
and its going to be colder and colder this time of the year .
dashing trough the snow in a one horse open sleigh
and thats why i keep the light shine on for 24/7 .
that way its about 20 degrees celsius in the closet night and day .
no dark cold shivering hours for my sweet little babies
these two autoos a minithunderfuck x autoduck and a lbh autoduck (little accident ) were germed 15 september .
and they have some more days maybe weeks to go .
just clear water for them no nutes anymore .
a sister of the minithunderfuck is hangin upside down drying out .
i ripped a dry piece of her sticky body and smoked it .
WOW feels good i like the taste and high of fresh nugs .
santa threw my a brandnew bulb throught the chimney .
it shines brighter than the brightest star and even more like my old lady .
its gonna be a cold cold cristmass without her .
no that was just a joke
