hi all....can i run a 600w hps in my closet without exhuast? with a fan blowing on the light?

[BDOGKush]

90f with low humidity sounds perfect....

 

[lonzo212]

90 is a little high unless your running co2

no...thermostat on floor... light foot half above that..says 95 now..pots on floor....raise light???/ fan blowin on high

Unless you have a fanblowing your hot air out pulling cold air in passively your just gonna fry your seedlings.

A fan inside does nothing but move air around unless you have it in a hole blowing it somewhere else

Unless you have a fan blowing cold air in on the outside maybe

 

[mrblu]

Sounds like you need to do more research or your gonna waste alot of time and money going trial and error

ok....I have to change something...way to hot....

 

[lonzo212]

could I lower ballast and still grow....would be so hot....would that help???

 

[lonzo212]

gotta switch closet ,,,have to have door open,,,b cooler...that's only way I think...with out having to do intake,,outtake...any ideas anybody? ty ty

 

[lonzo212]

I use herbies seed bank mostly google them you'll get alot of help choosing a seedbank in the seed and strain threads ..
as gor which closet I don't know how cold is too cold with an 600 hps I only have experience with the 400 in a closet that is 6x2x6 and it would get upward of 100 degrees if I didn't exhaust into the attic ... Your ganna have a big problem with smell if you don't exhaust it somewhere with a carbon filter attached . If smell isn't a concern than try to get an average temp of both closets and measurements of both (lxwxh) and post them up like I said I don't have any experience with not exhausting the light because heat is always my enemy but I'm sure there are people here who do have experience with it .. Also what kind of reflector do you have on your light .. An open wing ,hood,cooltube?
I would imagine cutting a hole in your door would cause you problems with light leaks into the room during flowering

your right ,,hot as hell...have to leave door open..its a hood...should I dim the light??? jus so I can grow...has three adjustments....thx for helping me

 

[green217]

closet is small ,,,3 by 4 ft maybe....is tall...gonna go with it...hope everything works out....lol ill adjust as I go....really need some good seeds...hope that order comes thru !!!!!!! air cooled hood is what it says....looks enclosed....could of got cool tube one or gull wing...I choose that one....was more then the others...I know doesn't mean better...goal is to not have to buy smoke anymore...that light to me is a life changer...I hope anyway....lmao

hell yeah it's a life changer if you do it right, get a cheap inline fan and some duct to vent that thing. Grab a carbon filter to, if u want to keep the smell down. I personally get a combo fan/carbon filter for around 80 or 90 US dollars on Amazon. Check out Breeders Boutique if you need beans, their prices are the lowest and the smoke is top quality. I've been running their gear for a year now, and just reupped on some more beans, they are having a 50% off special right now i think. Check them out though, the guys who run it are on RIU all the time, and are super helpful. Good luck dude, You are in the right place to learn, I'm super stoked with the knowledge i've picked up off this site in last couple of years.

ty ty...yes inline fan to vent that bad boy...its a freakin beast....should I turn setting down? or use 600mh bulb..jus need to grow....inline fan from window would cool room??? have to get it thru door !! lol do I have to exhaust??? my girl has a caebon filter air purifier...would that help??

 

[lonzo212]

waitin on seeds from herbies...hope I get em

sorry I haven't read any of the other replies so I might've answered questions already answered .. Honestly i don't know if you'll be able to cool it without some sort of fan sucking the exhaust out somewhere .. A door ,window,ceiling the only way r I've seen it work without that on these forums at least is a setup in a basement somewhere where its borderline freezing with no heat in the basement those lights out out aaalllloooot of heat . You could dim the light in assuming you've got one like me that goes 50% 75% or 100% if you dim the light to fifty you could still grow 2 or 3 decent plants but what's the point of having a 600 watter if your only running it halfway .. Also look into the lumen output on your bulb someone corrct me if I'm wrong i briefly researched this a week or so ago but MH bulbs run hotter because of a lower lumen output tha. HPS bulbs because basically the energy has to be distributed somehow ether through light or heat HPS bulbs have higher a lumen output therefore run cooler . But only slightly... Why do you not want to exhaust the light ? If that is absolutely not an option IDE recomend selling your 600 and learning about LEDS . I can't help you in that department i know absolutely nothing about them . I'm going to look into them for my sidelighting soon though. It seems to be the new age .. Good luck hope i could help

Glad to hear theyve never given me issues .. For smell if you dont exhaust with a carbon scrubber look into ona gel

Yes using the window as a intake to cool your light will work,but no

Look at a few youtube video's on venting aircooled hoods. It's pretty simple, you don't have to use the window as an intake to the fan. I just let it suck air from the room during veg and exhaust it out. I stick a carbon filter on there during flowering to knock the smell down. A lot of people just mount the carbon filter directly on the intake or sucking side of fan, and then run duct to hood this supplys the air that cools the light bulb. Then run one more peice of duct from hood out of room or in your case closet. I run a 1000watts and use a 440 cfm inline fan to cool. You will be fine vegging them with 600w. But if you want to save some money on the electric bill use a 400watt MH to veg then flower with the 600watt. Good luck. You should be good with herbies, but I'm telling you man check out BB next time you are looking for genetics.

yo ty ty ty....I have it going on the lowest setting its running 84f and staying there....with that work? should I use mh bulb for seed n veg then switch back hps for flower?? low saving money...lol

 

[mrblu]

return everything till you can do a proper grow. your just going to give yourself a headache without not being able to ventilate. your going to get caught by smell anyway.

You can get by with that temp, but keep an eye on it, it can get hot fast! Yeah use the MH for veg, and HPS for flower, some people use their MH for the first 2 weeks of flower, they say it keeps the plant from stretching as much. As far as seeds go, I use a cheap T8 florescent light, the roots seem to like that light, I let them stay under the T8 till they are ready to be transplanted out of the germination tray.

 

[noalibi]

Can you grow healthy plants without air? No. You need fresh air coming in to the room and you have to exhaust the hot smelly air out through a carbon filter. Proper ventilation is one of the biggest challenges in setting up a grow. If you don't dial in the ventilation, you will never grow anything but sick sad plants.

 

[Alienwidow]

Fan, carbon filter, yes. Youll need them both. We know, we grow, were not waiting on seeds from herbies. Do it.

should try to get the temp downto around 75 if u can. And keep an eye on humidity, if it gets to high when you have nice dense buds you run into mold, and u cant smoke moldy bud. This is one of the reasons ventilation is so important.
