Got my hydro bucket setup ready, cupboard converted, air ventilation and circulation sorted, seeds purchased from reputable source, but no lights. Looking for a 250 ballast setup, got cash and trade-ables. If anyone can hook me up drop me a pm, it'd be well appreciated. Cheers, Charlie.

Try crigslist or ebay.  RVF Garden Supply might sponsors this site sometimes to.  I personally roll with HID Hut.  http://www.hidhut.com/catalog/250w-hps-digital-ballast-bulb-and-economy-reflector-combo-120-p-412.html

Cheers for the link i checked it out it seems pretty good. What is your opinion on flourescent grow lights? It seems to me that it wouldn't cost too much to get a good setup for a single plant, and with several different bulbs maybe a more even spread of light can be achieved? http://www.hidhut.com/catalog/fluorescent-grow-lights-c-23_99.html?page=1&sort=2a -From site you linked.

You have spent too much to waste your time with florescent lights.  Compact Florescent Lamps (CFLs) have their place in cannabis growing, but bud flowered under them will lack density and mass.  I would use a metal halide or hps, 150 watts is good for one large plant.

How big is the cupboard and what sort of ventilation do you have?

Cupboard is 3ft wide 3ft deep 6ft high. Going to shorten to 4ft and using the entire 9sqft for scrog screen. Got a 125mm TT In-line Duct Fan setup, a 4in extractor fan, a few old PC fans and a wall mounted oscilating fan. Obviously not planning on using all those fans. Was thinking maybe extractor fan at bottom of cupboard and the TT In-line between scrog net/plants? Would this be sufficient if I was running a 250hps/mh for one plant? Cheers, Charlie.

Personally how I'd figure it out if you already had the fans is run a light and do a plantless run. Set up your cupboard and see how temps are I think this is more reliable than someone else's advice or experience as conditions differ so many factors.

For example if someone said they use a 250cfm fan for their 250w HPS in the same space (3x3x4 ft cabinet) and had sun facing wall (south part of their house near the exterior of the house) you may need far less cfm if you have a non sun facing wall. Now if you had a sun facing wall and they didnt and you used their cab as a model you could be in some trouble with heat.

In 9 square feet you should be running a 400 watt light, not a 250.

I think the 50w/sq ft rule only applies to open rooms that can be cooled adequately with ease. If you suspect you have cooling problems you definitely don't want to push the limits and find out you can't keep the temps down under 90f in flowering.

:thumbdown::onfire:

Any thing over 85F is going to shock your plants, you need to aim for 82F at max!

Unless if you have a bomb CO2 system (1,500ppm) going you can go almost as high as 95F

I think I'm going to go ahead and buy a 250, should be good for 1 nice plant at a time, besides I'm worried about the jump in electricity with a 400.

I don't have the cash for a CO2 system but i got a digi hygrometer and a digi thermometer so I'll keep a close eye on temps.

Mark my words: you will regret not buying a 400 Watt light.  They are a very similar price, and when you start flowering, you are going to realize that you should have gotten the bigger light. 
Trust me man, I know

To run a 400w and keep temps down adequately I'd have to move the grow out of the cupboard and make some sort of grow box as i can't drill holes in my walls, only the door of the cupboard, which would probably lead to inadequate ventilation. Maybe I'll put the project off a couple months, save up some extra cash and get myself some decent christmas presents. Cheers for the advice, Charlie.

Put it in a cool tube if you must.  attach a computer fan to the tube and run an exhaust out a hole in your door.  The difference in $ from buying a 250 watt bulb and ballast and a crappy hood versus buying a 400 watt in a cool tube is probably only like $100-$200, but your yield will be about 2x as large.

edit: you would need an intake from outside the grow area for the cool tube.

It's all relative to your humidity, airflow, co2, and temps. So long as your stomata aren't closed (to retain moisture) you're still fine.  I know commercial growers that don't run co2, have humidity as high as 70 and temps as high as 90 and don't run into problems. I never stated temps of 90 would be optimal I only stated you would want to be under 90F. I've grown in regions that have average daytime temps of over 90F. You probably wouldn't want your rootzone from hitting the mid to high 70s, but obviously we're on the same page as co2 won't allow you to run higher rootzone temperatures without increased risk of rootrot.

Could you elaborate on your use of the word "shock"?

The "over 85 degrees will shock your plants" is not true.  Magash has said this a few times.  All strains have different optimal temperatures.  If you have ever been to Humboldt county in August you will know that some plants still thrive in 95 degree heat.  I imagine similar conditions exist in the growing regions of Mexico.

"shock" is such a descriptive word too. It's almost like saying because.

I think the main thing is humidity. Indicas can take hot and dry but not hot and humid and Sativas thrive in hot and humid environments and don't mind arid environments.

You can literally plant indicas or sativas in soil or clay/sandy soils that are hot to the touch well over 100F and they will be fine. I've grown in places that have had continuous temps of over 90F and my plants were fine. Again, I wonder what this shock is.

I admit, optimal temps are under 90F and humidity should be in check too. No one likes moldy cannabis.

Computer fan will not cool a 400w light in a small area.

I agree with that the word shock might have been incorrect, but I hold to the argument that an indoor plant should not be exposed to heat over 85F.

I disagree with you both, I am quite certain that high humidity for am INDOOR Vegetating/Flowering plants will not solve any heat problem, instead I would think that it would limit the plant's ability to absorb CO2 and cause mold issues.

Nevertheless, outside you can find weed plants that grow native in climates as hot as 90F.  But that is a "genetic" trait!

To solve this dispute, Charlie what strain are you growing???

Do you expose your INDOOR Flowering/Veg. plants to 90F?

This Charlie guy is growing in a closet with limited CO2 ventilation and such so why would you refer to outdoors?

This is misleading...
