Hey Quix - sorry I got a couple of days behind. Looks like you have since moved on, but everyone tells me those UFO's are mostly good for maintaining a mom. I'm sure they veg fine like OMM said, too, but flowering not ideal. There are some LED panels that seem to perform okay for flowering, but they are pretty expensive.
What kind of reflector do you have for your new bulb? HPS bulbs run really hot. I've never used a 150w, but 400's run plenty hot. Everyone tells me 600's and 1000's are much hotter yet.
Here's what I think. In your space, you're doomed without a cooled reflector of some sort if you go HPS. I had a pretty good ventilation plan for the 400w in my new tent, but still struggled with keeping temps under 85f. What if you made a homemade "cooltube"? It's basically ducting on either end of a glass tube that holds your bulb/socket inside of it. Do a google search for "DIY cooltube". I've seen people make them out of a hurricane lamp glass tube and some ducting. You'd need to be able to vent the air out of the space, but if you can do that you might be able to even do 400w in there.
Your space is about the size of my Mothership in some respects, and I had a 400w in there. I've been knee deep in ventilation research and personal experience lately - let me know if I can help somehow. If you can, find a way to buy or build an air-cooled reflector and go 400w. 400w can be manageable for your space with ventilation.
my friend - you'll get this worked out. I like your new avatar a lot. Much better than the eye, too. (It was cool, mesmerizing, but kinda creeeeepy - OMM was right.)
Hey X thanks for the kind words, and encouragement and help
The UFO will go back in a couple of days, its not what I needed, and I'm kicking myself for allowing myself to give into the urge. Lol, it happens to the best of us once in a while I suppose. But at least I got to see one in action, and now I know a little more about them. As it stands, and as you and Jango have pointed out, any GOOD LED that would suit my needs would be way out of my price range....Lesson learned!
The HPS is a SunSystem fixture, from Sunlight Supply, with internal ballast(hate that part, but no one makes a 150w hps with external ballast that I can find...)
It boasts 16,000 lumens, and a 2x2 footprint. Now, I've been running it for 24 hours, and at first I was quite worried. While the 2x2 was closed up, it got up to 99 degrees F, FUUUUUUU@&!!! I only ran it like that for about 20 minutes to see how hot it would get. BUT, and a BIG but, with the 2x2 opened up, the closet door open, and the bedroom window A.C. unit set to 70, with the power saving option on, the 2x2 only got to 81 as of noon today, and 84 by the time I got home this evening. And the 84 was only because I accidentally left the bedroom door open when I left back to work at noon. SO....I think 81 is completely do-able. I ran temps higher than that on a regular basis last run. I dont mind running the ac like that either because I like my bedroom cool(I can see you shivering over ther OMM
)
Now, I REALLY like the idea of that cool tube you are talking about, and I WILL try it on my next grow. For now I'm settled on the 150, because I'm really over the stress of trying too many things, and not knowing if they'll work. But I have a feeling that cool tube WILL work, and I'm actually really excited to try it.
Thanks again for the idea, and for the kind words brother!!
Hey Quix.
Sorry, but xlr8 is right, those HPS bulbs are hot. Do you have an AC that you could pipe in there some how? How did you cool the CFLs, they put out heat too. Just trying to think of some way to cool things off for you. Trying to remember your set up. Don't give up Buddy!
Well, I kind of went on a rant there while responding to X, but to answer your question about the ac, yes I definitely do, and couldnt do what I'm doing without it thats for sure!!
Re your other question, I do have a 100 cfm fan pulling hot air off the top of the space, and a slightly smaller fan at the bottom corner, to help draw cool air in. But its nowhere near enough to cool that damn HPS. I'll be trying to put together Mid-grow-update" Kinda like half time for a football game, full of pictures of the beginning, and of lately, the clones, and all the things that have changed. You'll be able to see the setup at that time, but it's very small. 2x2 about 6' high.
Anyway, thank you for the encouragement my friend, I'll never give up trust me on that one!!
