150w HPS Club and Resource Guide......

[Guest]

Check out this website for the PC power supply wiring codes to see if you are hooked up using +12V and Common.

That fan motor is pretty hefty. Usually motors are fused at 1.5 times the full load current rating of the motor so the the motor likely draws around 5-6 amps on startup.

I'd say the PC supply is too light and is tripping on an overload while trying to start the fan motor. There are multiple voltage outputs from these supplies and each +12V output may only provide a couple of amps.

One other trick you can do is to tie all the 12V wires together from the power supply so that the current from each individual supply circuit adds to the overall output current.

Can you get a battery charger to try it out?

Cooling options for 150 watt cabinets

Alrighty, I'm high as a kite, and I was thinking about some possible way to cool my cabinet when the ridiculous summer temperatures come around again. I was wondering if anybody ever thought of this, or did something similar to their cabinet.

One way to get a cabinet slightly cooler, is to have a remote ballast, but that won't help much to combat summer hell. Another way to bring the temps down a little bit is to use a fan that pushes more air, but even a 1000 CFM fan won't do any good, if the ambient temperature is way too hot. Another option is to have an AC in the room where the cabinet is located, but unfortunately for me, that is not an option, so I've been thinking about alternatives.

What about an AC for just the grow cabinet ? Since most 150 watt cabinets are not that large, I imagine that a fairly small AC would do the job. With a temperature probe, I would imagine that you would be able to dial in the temperature to exactly where you want it at, giving better yields and better growth. Also, since it's a tiny AC, it would consume far less power than a standard AC, thus making it economical to run.

What about something like that ? Sound like a good idea ? Shitty idea ?

To be able to grow all year round without any worries at all about heat issues, would be awesome indeed.

Hey where did you find the tube?

Bake-a-Round from ebay. It was $14.95 incl. shipping, but i saw them going for $20 regularly, prices are going up on them as they are becoming popular as cooltubes i think.

The fine people in this club have been a huge help designing and growing. I just reworked my cab to have my remote ballasted 150 horizontal instead of vertical. And I had my computer fan rigged to force air in but decided on that 2x passive intake from what people said here, so I reworked that too. I'll be using the 150 to flower and I'll be using up to 8 "daylight" 26W cfls to veg. I'm working on the cooling system for my final steps. I need to get stroking a little cause I have 2 white widow beans germing now. I have put together a ducting system for cooling the cab as well as the ballast. Inside the cab I have a computer fan aimed at the bulbs and across the plants, so I'll get thick, strong colas. One final (and hopefully last) question is about the fan I am using in that duct. This fan (can't post link, dammit) is the Suncourt DB204P Pro 4" Inline Inductor Duct Fan Booster that can be found on Amazon. It only pushes 80 cfm which I think is enough for a 150 but my hesitation is that air temp. isn't supposed to exceed 140F. Is the air going to be that hot after going 6' through ducting already?

Looks interesting, where did you find that at? I don't think temps get high enough in my area to warrant one, but i'm sure it would interest a lot of people.

I was looking around for thermoelectric air conditioners and found a few companies that make them. They're usually used for electronic enclosures I believe. I don't see why they wouldn't work fine for a plant cabinet also. They even have ones that can cool & heat, according to what you desire at the moment.

I also meant to mention that I wasn't able to find warranty info about Suncourt fans, from Amazon or the website that sells them. That makes me kind of leery, but $35 delivered for a small inline makes it enticing, even if I have to wire it up myself.

I'm definitely no expert on fans, but the fan that you mentioned is a duct booster fan, and I don't believe that those fans are the best things to use if you're planning on using it as your main exhaust fan. Somebody else with more fan knowledge will chime in for sure. Also, try to find out about the noise, if that concerns you, because plenty of cheap, shitty fans are annoyingly loud. Even some expensive fans (vortex I read), are loud as crap.

hey greenhead, i like the look of those a/cs. did you find any places that actually sold them instead of making you fill out forms to get a quote?

Haha, yeah, they seem hard for a regular consumer to purchase. Even to find out the price seems like a hassle. This reminds me of when I posted a link to a material that had better reflectivity than mylar. Only problem was that it seemed impossible to buy for the regular public !

Out of all of the companies that I saw making the small thermoelectric AC's, only one actually had a price listed. This model is $200.00. I think you'd need to purchase a seperate power supply also.

If those things really worked good, and allowed year round growing, then it would obviously pay for itself after just 1 harvest.

GO GIANTS!!!!

Anybody ever tried mounting a 150w in a rubbermaid container? How hot do the bulbs actually get? I have a rubbermaid grow box with 270 watts of CFL's but would like to go to an HPS to increase the nugs density.

Any ideas?

Thanks in advance!

 

[Pipedream]

If humidity isn't a problem in your set-up, you can always consider an inexpensive "swamp cooler" or even build one your self.

I think it's been tried and is not recommended - maybe red_Green tried it? not sure - but I think the rubbermaid tends to get warm enough to start smelling of plastic.

That looks like something that would be really cool to have with a small cab for us 150watters. I wonder how well they work and how long they last for... It would def. be a good investment in the long run.. I wonder how hard it would be to diy something like that hmm...

OK, thanks suga. I'll wait to set up the 150 until I have my cab finished. The CFL's seem to be doing OK for now anyway!

Dude: AWESOME looking grow! Congrats man. Thanks for sharing the pix. Very insperational. God I can't wait to get growing again.
What does "0,3m^2 78/58flo" mean?
