I tried searching this thread, but couldn't find anything about light diffusers. I had one on my 250 W cooltube that is attached to an adjust-a-wing medium size, but recently took it off to see if it was even necessary. Has anyone used one?

I never used one. I don't think the 250s get hot enough to need em and from what I have read with most of the modern lamps you not need em anymore.

I am a stoner and I am thinking a light diffuser is the thing that hangs under bulbs on the batwing reflectors to calm the hotspot below the bulb. If that is not what it is then aaaaaaaaaahm. Bump. lol

Sorry for the complete random post, just wanted to say how it seems a lot of people under estimate a 250w HPS, i have flowered a 4-5 ft plant thet yielded almost 8 oz all under a 250w. The tops of my plants have been as close as 3inches from the bulb with no signs of burning or heat streest at all, just have a oscillating fan blowing right behind it and the heat is almost non excistent. Nice1

Yeah not surprised. I used to work for them about 4 years ago.We always threw boxes when loading/unloading the trailers. I worked in the trailers unloaded and also as a driver. So blame those stupid part timers not that poor driver, cause he works his ass off I guarantee it. I feel for ya man, gonna take about another week to get your light.

Damn I read the first 10 pages but I can't get thru it all i still gotta get up tomorrow.
So I'm a first time grower and just finished building my stealth closet 6/3/2ft.
I'm going to use 250w HPS Lumatek Ballast all the way. The bulb I got should be good for vegging also, as it was recommended by the growshop. Not sure about blue spectrums and all its not written on the packaging.

I tested the climate in the closet so I turned on the exhaust fan (10cm/180m3), and had the HPS hanging about 2.7 ft above the floor. Air is coming in thru an opening which is twice as the opening for the outtake fan. Temperature reached 83 F and humidity dropped to 28-30%. When its off, its 70 F and 50% humidity.
Is this normal? I actually didnt expect to get heat problems with a 250w HPS.

I just started germinating the seeds and I'm wondering if this will be a good start for them? When should I start putting them under the 18/6 and how far away that they wont burn nore stretch?

Thanks!!!

dont have a cooltube but i will get one if it helps. By how much were you able to reduce the temp in your box with the cooltube?

If your grow room is 70f when the light is off, than with the light in a cooltube you will get the temps with the light on closer to 75f. When i ran the 250w in my cooltube i never had to worry about my temps going over 78f. Put it in a cooltube and you will never have to worry about it. And you can get the light alot closer to the plants when using a cooltube.

Right on with what buster said. I have my cool tube 6 in from the plant and it stays 78-79 at the canopy. There are simple ways to build a cool tube but I got mine from a dude on eBay that makes em and sells em for 50 bucks. Only difference from the expensive ones is its 5" instead of 6" but its well worth the money.

I've never needed a cool tube for my 250, and I don't have heat problems. I can also get the light nice and close to the plants, to the point where light bleaching is more of an issue than heat. I have a small fan pointed at the bulb, which helps, but I also have larger intakes than yours (4x the outtake area). I believe that this is the main reason I have no heat problems, and I think that 2x isn't really enough. I've read that around 5x is the optimum size for passives, when using a centrifugal fan.

thanks I'm going to test that. Before I make any new holes I'll just let the cab door slighlty open, and check if that helps. Are you able to control the odor with an intake of that size? Is there a rule on how big the intake opening can be without compromising odor?

I have no odor problems at all, and I still get good negative pressure. The initial post that i read about the 5x optimum intake size was pretty indepth, with figures and stuff about fan flow rates, but I don't remember the specifics unfortunately, just the conclusions.

I posted this in the 400w club thread earlier but will post it here as well since I am still considering a 250w system too.

I have a quick question for all of you 250w users. I am looking to upgrade to a 250 in the future, but the shipping to where I live has been ridiculous on the systems I have looked at so far. I found this earlier but didn't pursue it because I kept looking at grow specific lights. I am beginning to see this as my best option though and am looking for others' opinions on it before making a purchase. Have any of you ever used anything by econolight, and do their systems last? I would likely buy this light http://www.e-conolight.com/wall-packs/cutoff/cut-off-250-400w-hid/e-wpdh25qz.html and purchase a grow specific bulb elsewhere to use in place of the bulb it comes with.

Also, would it be better to purchase both MH and HPS bulbs or just a HPS or CMH bulb? I have grown with CFLs and a 150w HPS before, but am looking to upgrade to a larger light that could cover a couple decent sized plants as well as light for some of my indoor veggies. If this does not seem like a good idea, what would you suggest instead? Heat is not an issue as I can remote the ballast myself and it will be in a decent sized closet (6' x 2.5' x 6' lwh) with good ventilation.

I started with a 250W MH and it was great!!! I grew for 4 weeks in Flower on a 250W HPS... But then upstaged to a 400W HPS on a boostable Lumatec Ballest and am currently running the Boost in my final couple of weeks until Harvest :) But just to support the 'cause 250's expecially the MH's are GREAT !!!

IGNORE The missleading title...I only manage to get up to 400, the 600 was too hot! Here's a LINK to my thread...Theres tones to read but its all great! Lol :)

Took a quick look at the light you are looking at. The trouble with security lights is that they often don't spread the light the way a grow-oriented reflector will. To make the footprint of light big enough, you might have to set the light too far away from the plants to be effective.

Here is an inexpensive and light (read: low shipping cost) option:

Also, if you by a CMH bulb, it will be good for the whole grow, no MH or HPS necessary-- that's one of the charms of that type of bulb.
