150w HPS Club: Inspirational Resource

good looking box redivider, I am amazed you can keep the heat that low with a hps in a rubbermaid

Click to expand...

what I did was put one computer fan, 120mm right above the light, (in the pic you can hardly see it on the left side above the light) pulling air out.. the hood has little vent holes right there where a lot of the heat (i'd say about 40 percent of the heat) rises through, and gets expelled instantly.

the rest of the heat is generated by the light itself. to handle this i put an 80mm fan in the back (which you can see in the pic) blowing cool air in.... there's also 4 passive intakes in the bottom on the sides...

i think it's gonna be a struggle getting that to run completely cool with the two lone fans. i'll probably change the fan that's above the light with a 70cfm pc fan off newegg. and take the one that's above it and move it to the back where the 80mm fan currently sits.... the temps will def. be under control then.....

what i like most about this is that it has a little latch on the lid, so when I close it it latches shut, no chance of it falling for some random reason.....

redivider, i'm pretty sure your going to run into heat issues. If you could rig up a cool tube, that should really help. I had the same fixture as you and it was crazy hot, even at 10" away from the plant, and I am in a bigger space. With the cool tube set up, I can grab the glass and it's cool. I can get the plant inches away without issue. Something to think about, could diy pretty cheap.

i ran it for 12 hrs the other day and the temps were the ones i posted above.

i'm anticipating some heat issues when the screen fills out since one fan is below the screen. i'll get another PC fan and hook it up just in case.... then i'll know i'll be good...

congrats man, you seem to have it figured out, good luck on the scrog

Hello,
This is my first post. I've been reading alot. Great place to get info. My question is about the 150 w hid. I've been using cfl's, but I wanted to add the 150 w hid. I got a Sylvania from Lowe's. The first one did not work, because it was broke. A piece of something was loose in the bulb. So, I took it back and got a different one. I pulled one of the cfl's and screwed in the 150. It does not work. My question is, do I need to get something different for this type of light or did I get a bad one again? I'm growing a single plant, Swiss Cheese. Thanks ahead of time for any help.

HPS need a separate ballast to fire the bulb. I'm not sure what kind of bulb you got that screws into a regular bulb socket. Most HPS use a mogul socket, which is bigger in diameter and generally made of porcelain to handle the heat produced. Can you link to what you actually bought so we can see what's going on?

for cheap money you can get a 150 watt at home depot. if your going to use cfl's with it, then you can use a 70 watt light. hid light use a ballast, ignighter and a porcelane mogal. if you go to home depot or lowes you will find them in the outdoor lighting section.
I would recommend going and looking at them. i paid something like 40 for a 70 watt mh. for veggin, two of them work great for me.
also what people dont think of is heat. ive seen many people change from cfl to hid and burn the piss out of them. just watch the temps.
also good luck

Thanks whynot and hookahchill. That answers my question. I understand the heat problem. I will keep an eye on it, thanks.

sup yall. been away for a long while n thought id drop in n see what shakin with you guys...mistermicro n co you still in here??

im just about to rig up another vertical 150w BOG, similar to the ones i built/we discussed much much earlier in this thread..if required i'll post the build up, as i mod the barrel n setup.

guess i better read back n see what i missed over the last 10mths

ps is chat down???

First grow. Just one plant in soil under a 150. She is about 46 days from when the seed popped. Lights were switched to 12/12 three weeks ago. Last pics are at day 42. Ran into a few problems along the way but she seems to be straightening out. I did some LST so she's pretty much growing on her side. Seem to be getting a lot better coverage however now that it is forming an even canopy. Hopefully it will work out. Enjoy.

ok so here's the plan for the next 150w setup...
1 x 150w HPS (originally from Lowes) that has been converted to remote ballast gear(refer to my post in DIY or very early on in this thread for remoting procedure) - with pc fan blower to cool the ballast - HPS will be hung vertically in DIY glass shroud/cool tube...not sure whether ima use the bake-a-round i have, or i may use 4mm glass and allow ample space around the bulb so as not to stress the glass during use(its fine so long as you have sufficient cooling and ample space)
1 x plastic barrel with sealable snap ring lid (850mm x 480mm)
1 x 120mm 12v exhaust fan driven by 12v variable resistor transformer (3-12v ac/dc) Fan to be mounted inside the barrel at the bottom of cooltube setup, blowing up and out of lid through diy scrubber.
1 x DIY automobile bulkhead steering shaft grommet wrapped with carbon oven hood filter for inlet mounted on bottom section of barrel for inlet.
1 x DIY exhaust scrubber mounted to 120mm fan outlet in lid,made again with oven hood carbon filter(smell is not too much of an issue for me,but any minimization is a bonus)
The barrel has been painted FLAT white inside(drying as i type)
The strain is to be a freshly imported UK Cheese clone thx buddy, youo know who ya are if yer reading this)..Itll be topped several times during its brief veg time(poss only 3wks)
It will be a 1.5 gal hempy bucket grow using ionics grow/bloom nutes and ionics boost in final phase.
Hempy buckets for the uninitiated are a LO-FI static hydro, consisting of a bucket filled with perlite/vermiculte 1:1 ratio, 5mm hole drilled 3" up on the side of bucket, which acts as your Reservoir, the rest of the bucket whilst absorbing moisture also allows mega amounts of air to the upper roots, whilst the lower rootball section sits in the water/nute mix and drinks what it wants when it wants... works like a charm, yields well, and is soo simple you wouldnt believe.

This is to be my last indoor grow sooooooo i hope it goes smoothly....although i do have a guerilla planned for this yrs season...

wish me luck n i'll post pics of the barrel build as i do it next wkend :

later yall

why the hell would anyone want to use those cheap ass HPS "flood lights" from Lowes or Home Depot??

I mean hell man.. you can get a REAL 150watt HPS system (lamp, bulb, with built in ballast) for under $100

I run two 150's (along with 4 150watt CFL bulbs for side lighting)... and I paid WELL under 2 bills for both 150's.

just saying.. spend the extra 20 or 40 bucks and get the real deal man.

Plus, you really risk the chance of fire using/rigging up something that doesn't belong indoors.

Use your brains kids!

peace..

Why?? exactly that reason theyre cheap.. ive owned cheap assed lowes setups and "Grow" style 150's and inside theyre exactly the same...just a better reflector on 'grow' lamps..hydro co's are charging you more $$ for the same thing available at lowes...its not rocket science.. no offense.

Built in ballast lights are ok if you have room, but due to the fact most 150ers are utilizing small cabs, they take up too much room and due to the ballast also being in the grow space it increases latent heat ALOT...

I run two 150's (along with 4 150watt CFL bulbs for side lighting)... and I paid WELL under 2 bills for both 150's.

I used to run 2 x 150s, both with diy remote ballast and paid 80 bucks for the both,

just saying.. spend the extra 20 or 40 bucks and get the real deal man.

Yes you do, but, if youre SENSIBLE and follow the multitude of advice available online about remoting these, theyre safe.
Ie ensure youre earthed properly,no overloaded sockets, no exposed wiring, secure fixing plate, possibly make a shroud and cool the ballast too, which is what i do.....all make for a safer sys....
My last Cab utilized the exhaust fans ducting thru a box containing both ballasts, and air cooled them.

Use your brains kids!
exactly, common sense will see you a long way in this life...safety is critical for you and those around your setup...ignore the obvious and you may just regret it.

peace..

Check out my 150w CMH grow.

Hello,everybody.
Tell me,what max size grow box can be if i grow with 150w HPS (17000lm)? My last grow was in 55cm x 55cm x 140cm box. And what grow mtod is the best for 150w HPS? LST,scrog or just let it grow simply?
