in theory would a 600w hps (95,000lumen output claim) in a closet 3ftx3ft x9ft*heigh* be a major fire hazard or damage anything? Also, ventilation wise the intake should be bigger then the exhaust or vice versa. Last but not least could tinfoil be used to line the walls without damaging vegetation with intense light spots until mylar can be obtained?
Thanks
1. You would be better off using flat white paint, on your walls. IMO
2. Your gonna need a serious ventilation system to keep the heat/airflow under control. Intake should be larger.
3. Any quality light system is not a fire hazard.
4. Whatever you decide on, test it, for several days; before popping the seeds.
ummm.... I would think twice and very hard about that light in such a small space. Quality does not equal safety. You can be safe about it for as little effort as a smoke detector in the closet. Burning or potentially burning a house down is not worth the ounce or two that the closet will give you.
just my thoughts.
Running a 600HPS is best accomplished in a space at least 4x4 feet footprint and 8 feet high. Your closet size is appropriate for a 400HPS.
It's good that you have the height. You will need it to put your exhaust blower. Rememnber a light and its exhaust should be considered a single unit- buy them together to suit your space.
Tinfoil is crappy. Paint it white like the Pimp said.
Plan to keep your ballast up off the ground, preferably outside the closet.
Install a fire detector and keep an extinguisher handy.
Plan how you will get stale air out of the closet- if you rent, it may mean buying a spare closet door that you can cut a couple holes in, and building a baffle over the hole for the end of the duct and a flap over your passive intake slot at the bottom.
im in a 3x4x6h with a 6" 450cfm vortex with excellent ventelation. 1 thing is you need to vent outside the house if all possible if not atleast into another area than where your intake is located. the light will produce some heat
What if the person is using a cool tube with a fan like texas grass is using.... and maybe a secondary 450cfm fan exhausting the room.
I think it's possible with the right cooling/ventilation.
if you buy a nice inline fan and use a cool tube reflector you should be fine methinks.
i am currently running a 600 in a 4x2x8 closet with a 6" cooltube and a 6" vortex fan mounted in the attic. Temps stay in the high 70's to low 80's and everyone seems to be happy in there. i thought about a 400 but decided to go with the 600 for a little more money.
Not trying to hijack but......
I was in Menards the other day and was wandering around the lighting section. I came upon some HPS bulbs and was looking around. I found some bulbs where the wattage went from 35w up to 250w I believe.
Here is my question....say I have a friend who used 6 - 4ft. flouros for their last grow. Well, I was thinking he could buy 4 - 100w HPS bulbs to use instead. I asked the lady working and she said the bulbs can be used in a regular light socket. Being how they are only 100w I didn't see why not.
Cause obviously 4 - 100w HPS would put out more lumen's than the flouros, correct? His basement stays cool and ventilation is good. The area is 5ft x 2 1/2 ft and about 3 ft. tall.
What you guys think since we are on the topic?
your probably better off going with one 400 or 600 hps. 5 ballasts is going to kill your pockets. The fluros are al right but HPS is a whole new ball park as far as intensity goes (hence the term HID!)
personally, I've never thought of that. it would save all the money needed for a ballast and lamp setup. you'd also be able to get more control over the lighting with individual bulbs (you wouldn't have to have all the light centralized). but I still doubt you'd match the 400 Watt bulb lumen for lumen, although you could probably come pretty damn close. HID bulbs are very efficient when it comes to comparing energy consumption against lumen output, and their efficiency increases in higher wattages.Quote:

She told you wrong, you need a ballast.Quote:

Why would you want your light cutting out? The real solution would be to resolve your heat issues either with better ventilation or less light/heat.Quote:

I wouldn't recommend this method. That's just me though.
you very much can.. i ran a 600 watt in a 2X2X8 foot room.. 160 CFM fan vented to attic, and a similar fan sucking air in from the attic. Light was in a cool tube, which barely fit at an angle in the closet. I was doing this in the winter time, starting in october and shutting down in the end of april.
No way no how could this be done in the summer, temps would be astronomical.
It sucked being limited in space, but as long as i could grow i was a happy camper.
My 600 HPS grow was done in a 2x2 area with 6 ft of height space
check out my log in my sig
Litup, The biggest problem I see is the 3' height...
I dunno if this is old, but I dont usaully post here. I use a 600w HPS in a space 2widex5longx9tall, its hooked to a 6" valuline, it connects thru the top of the hood with a homemade adapter (think oldder sun systems hood with air kit), I removed the glass as well cause I figured my space wold be small enuf to use one fan for venting, then ran that to the ceiling and vented it to the mini attic. My plants can grow to within 10" of the BULB with no stress. All I got running is two small 9" fans to strenthen stems with that blower and I can leave the door closed temps @ 78 here in summer in cali.
Once upon a time in a similar situation my response was to cut a hole in the drywall and add in a shower fan pullling air in from an air-condition room with the fan connected to a thermostatic switch. The switch was around thirty bucks and the fan was around sixty. More effective higher powered fans are nice but can really raise the sound levels.
