IS THIS HAZARDOUS?

[chisme]

Hi all just outta intrest would a 400w hps lamp with ballast be ok to run in a cupboard about 2 1/2foot x 2 1/2foot square and about 10foot high? or would it just cause too much heat? and be a fire hazard?

run a "cool-tube" or otherwise fans with good ventilation ... and hope the fan doesn't take a dump when nobody's home ..... go here:

problem i have no cash left


so it is a hazard then? it wouldnt run good in there?

[justaseed]

i doesn't really matter if it will be a fire hazard because it will be way to hot, without good ventillation, to grow anything anyway.

That would be alot of heat. If you had the ballast on the outside of the box and ran wires into it that would help to reduce your heat and I believe would remove the "fire hazard" risk.

Get a small fan and mount it on one side of the box like an exhaust fan on the topside of one side and bore out a nice size hole on the other lower side. That would definately help!

Good luck with the grow!:thumbsup:

mmm ok how about say if i used all flou for vegative then when i decide to go 12/12 i use the 400hps? would that be ok?

because then i would be able to moniter most of the use

[Psycho4Bud]

That's how I did my first grow. Money was tight so I went with the flo's during veg cycle and lucky enough was able to afford a HPS when I hit flowering. If you go with the flo's just stay away from the daylighter lamps...it's recommended to use a combo of soft white and cool white.

Good luck with the grow!:thumbsup:

yeah me too i jusr worked out how muhc it would cost to run a hps (allot) about £25 for maybee 2 on cycles at 12/12

Like they said heat is an issue with HPS so just switch to CFL until you get some more money to install the HPS light and are ready to deal with the heat they generate.

in california it costs about $85 a month to run a 1kw hps on 12/12

Hps are alot cheaper to run that that. a 400w HPS on 18/6 for three months would cost £35-40, would you call that alot, I don't. I have a very similar size grow space to you and the only real heat problem is the heat underneath the light, it literally burns the ground so you have to watch out. If I was you I would make a hole in the top of your closet so you can install a inline extraction fan connected to a carbon scrubber. They are expensive. But you can pick up the fan, the scrubber and ducting for less than £200, and that will sort your heat problems, your ventilation problems, and your odor problems all in one and no maintenance. So personally I would find the money and do that. If if your strapped for cash then there's not much you can do to tackle a 400w HPS except not use it.

my rate here in No Cal is .0924 cents per Kilowatt, so a 1000 watt lamp for 12 hour day, 31 days, would be about $34 ... hope that helps some ... :smokin:

thanks very muhc for the pound info on 12/12 light cycle hps i was wondering about cost and that sound okish lol im sorta unemployed despratly seeking work i can get a full extractor fan like this one...well this IS it exact same one= http://www.growell.co.uk/p/0231/GroWell_Complete_Extraction_Filtration_Kits.html

if i cut a round hole in roof of closet then hung the fan tube throu the hole and store the actual fan in the loft would that do for the heat?

also do u all use extension leads ofr your growrooms? as mine has no in built wall socket im having to use an extension lead its making me paraniod if i plug a 6socket extension lead into the wall then run the 400w hps 3x24w cfls and extracor fan woud it blow?

really, that's alot cheaper than i thought. i have a friend in garberville that runs 8kw of hps and he was the one who told me that it was $85 a month for 1kw. sorry for posting bad information.

[the image reaper]

no prob, I failed to mention, I get a 'break' on my PG&E electric, because Im POOR ... lol, but it doesnt amount to much of a discount, $5-$6 month or so ... either way, electric bill is far outweighed by price of bud, and satisfaction of smoking your own effort ... :smokin:

[chisme]

LOL as long as i dont burn my house down im cool lol
