Nice job, SmokeyTheBear. How are your temps?
150w HPS Club and Resource Guide......
- Thread starter Pipedream
- Start date
with the light as low as it can go. the temp is 82. when i put the light where it will be when the plants are full size. the temp is 77.

I agree. I found a cheapo CPU fan/heatsink laying in my closet from YEARS ago and I popped the fan off, wired it up and it is the ONLY thing cooling my 150w HPS. The 150w HPS bulbs dont get real hot compared to higher wattage ones, but if you dont have any air moving around the bulb, the heat can build up FAST!
I once saw a cab where the guy used a heavy duty 120mm fan to cool the bulb, and his plant tops were an inch from the bulb!! Talk about maximizing lumens!!

DIY 150W Cabinet
DIY 150W Cabinet
I was playing with SketchUp, designing a flowering cabinet for:
- one 150W HPS
- 24"x18" SCROG screen, with 1" PVC pipe frame (total dimension with frame: 26"x20")
- up to 9" tall tub/pots
- remote ballast, timer, pump, and other components
- one Panasonic Whisper 80 CFM Ceiling Exhaust Fan with Bulenath scrubber
- around 4 air changes per minute, but adding the gear will increase to 5.
- flowering room sliding drawer (not shown)
- built in lightproof passive intake (19.44 sq in) for a 4" exhaust
(utility room intake not shown: if ac reflector or cooltube is used then a 6" duct, if bare bulb then front of floor can be 3/4" less in depth)
Softwood timber frame:
Nominal: 1 x 1 Actual: 3/4 x 3/4
Nominal: 1 x 2 Actual: 3/4 x 1 1/2
Nominal: 1 x 3 Actual: 3/4 x 2 1/2
Nominal: 2 x 3 Actual: 1 1/2 x 2 1/2
Plywood walls: 1/2"
Plywood removable top: 3/4"
These are the MAX cabinet dimensions. Realistically, this will be less tall, wide and deep. I just wanted to see the max size for an 80 CFM exaust fan.
Design can be re-sized for a veg cab as well.
All dimensions were taken from ICMAG, especially from the 150W club.

only thing i can do is rig up a 5 inch computer fan to blow across the bulb. is that even worth it? otherwise i cannot do anything.
Yes, it's worth it. My bulb pc fan is only 3". Your fan will be like a/c, lol.

Heck yeah its worth it. Its all about not letting the heat build up. Even the most gentle of breezes can drop temps significantly. My canopy temp is EASILY 5 degrees cooler after adding my crappy little fan. A 5in computer fan is honestly about as big as I would go! Rig it up to a DC adapter (you can find DIYs everywhere) so you can plug it into the wall & you're good to go! You will be surprised how much of a difference it makes.

after the first two batches of auto-flowers are done i'm going to try my hand at a scrog grow. the strain i'm thinking of using is Nirvana's Papaya. I've had my eye on it for years but did not think it would perform well outside. I'm thinking about Barneys Sweet Tooth or Dutch Passion Frisian Dew as well for a strain after the Papaya. i want to get two different kinds so i can save 3 of each for an outdoor run next year. anyone have any suggestions?
Bear, it might help to have an idea of the stretch. That way you get the screen nice and full. Just my 2c.

hey guys and gals! I started up another little run under my 150w HPS last week..it took the seeds a few days to germ, but I have 3 little babies now...the oldest one died somehow though...went to check on it earlier and it had fallen over and couldn't stand on its own...could have had 4, but it's all good..I still have some seeds for a few more runs, but after that I dunno..maybe have to start making my own seeds..lol..
anyways, hope all of you are enjoying summer..it's been pretty nice here, but uneventful for the most part...can't wait to get a ride so I can go on some road trips..
take care everyone!
pS...after drying my last harvest, I came out with some good nugs...not a lot in terms of weight, but it will last a while...got it curing now in the pantry in a jar..

good to hear igrowtrees good luck on getting a bigger harvest next time around
and reefire i would say it depends on your genetics and your environment but you can expect anything from 1.5 oz to 5 oz
my goal is 5 this time around i got about 4 last time with alot of vertical space and some northernlights

I was wondering if you guys thought 6 plants in this soil set-up would be too much-they've been under 12/12 for 2 weeks.The strain is big bang.I'm using a 150w hps/52w cfl/48w of T-5.The tent is 2x2-4' high.Duct cooled with a 400cfm fan.All in gallon pots.The hps is raised in the pics-usually 3" from canopy with no probs.

It may not be "too much", but you are pushing the limits.
I know because it's not all that different from what I do.
They look happy, so stick with it ant try to get it dialed-in a bit.
Keeping the lights as close as possible will be key in your situation to eliminate stretch.
After your first run or two you'll know better what you may want to modify.

Thank you Pipedream, but I decided to go with 4-something didnt seem right with the girls packed in there.So, I gave the 2 straggliest to a bud with a little grow of her own.I got a TON of info here-no doubt the most informative thread I've read, thanks again Pipedream-I'll keep yal posted.peace

HEY Everyone! All of you are awesome! I can read and read and read forever with this site, and learn something new everyday. Well, I harvested one of mine today, sprouted on the 12 of May, flowering started June 20, and harvested today, for a total of 40.2 wet. I'm not complaining, could of did a lot better, twas my first grow though. I do have some what of a problem. Most of the buds are hanging upside down right now, I have many little small buds I can't hang upside down. I was wondering if I leave them sit on a pan to dry would it be ok?
