My grow space is 22 inches by 45 inches and I would like to get a 1K HPS for it. Do any of you think this is to much for the small area. Of coures a air cooled one! Any imput is always usefull. Thanks

That light will work just fine for your space.
HAPPY GROWING :)
Even with air cooled hoods you could still have a heat proplem, window unit AC would fix that. Try a 600 w for that size space you will have less problems with heat.
It is possible to over light your plants.... it can also happen in nature at very high elevations... the plants will turn white/yellow... they loose their chlorophyl... it is different than necrosis, the plant will look healthy except the top will be white/yellow... the growth in this area (usualy just the top of the plant in indoor situations) will stop and will not continue until the light is reduced... when the light is raised/reduced the top will turn green again and growth will resume..
: )
So Garden knowm are you saying tha this is to much light or just stating that you can over light your plants?
You have 6.75 sq. ft.
At an optimal level of 7000 Lumens per sq ft.... you need 47,000 lumens.
Your HPS at 1000W will provide about 140,000 lumen at 2 feet.
I suppose that could be over kill but since you are talking HPS I dont think you have an issue.
I really think you should consider a 500W MH and 500W HPS combo unit though. Yes you can grow from start to finsih with HPS but I just don't believe it will bring out the full potential of the plants.
They need blue spectrum lighting and the HPS just doesnt deliver enough of it.
Anyhow, in the unlikely event it stresses your crops, raise the lights further away and you'll be fine.
Just mine .02 for ya....
HAPPY GROWING :)
The light I have been looking at comes with # 1,000 watt AGROMAX HIGH PRESSURE SODIUM High Output Horticultural bulb
# 1,000 watt AGROMAX METAL HALIDE High Output Horticultural Conversion bulb
Do not get a 1000w
I have a 600w horti for a 15 sqft space and it is just about right, in fact I should of got a 400w instead but my original spot would have been fine for 600w but 1000w will be over kill. The 600w cost a little more than a 1000w but less heat and will be more then enough for you in that space
I have a 1000W... it's big, bright as hell, and hot. Add a "really" infront of all of those. My fairly well ventilated room (with carbon scrubber) sits between 90-100F.
I dont want to get a 600 watt because i cost more than the 1000 watt. I want the most light i can put in there though. i was going to mount the light on the roof so wouldnt i add that to the sqaure feet?
ive got 2400 w on lm X 1m. is this too much light. my temps around 85 C max. by too much light i mean is there a chance it may decrease harvest, cos i always thought more light = more bud. its about 3 weeks in now and ive had to stake all the main branches- its only one plant, so that dont seem so bad. ive got an nft tray sat on the outskirts and a box with a few growing in coco

Dude, it is difficult to have too much light.
I am running now,
250W MH
250W HPS
125W CFL
125W CFL
125W CFL
65W CFL
65W CFL
65W CFL
The MH & HPS light the canopy and the CFL's light the sides and undergrowth.
My plants are growing an inch a day now.
And my grow space is only 3.75 sq. ft.
Quit farting around and get it. :D
HAPPY GROWING :)
Yes, tomorrow i am going to Home Depot. The have those tiny little window AC units that are about as small as a microwave. $77.95.Quote:

Maybe that will reduce my water usage because I am going thru 1.5 fricking gallons of water a day, PER PLANT! :eek: :eek: :eek:
Thats a lot of water mixing and pH adjusting.
I'll post a pic after I set it up.
The kids think I have a vegetable garden in there...though the older ones surely aren't so gullible.....
Now when they see a damn AC unit sticking out the back, they're really gonna wonder........
So if i have an intake and exaust just for the light you think ill still need a ac unit?
That only helps to remove heat build up from the light. It will only save you about 7-12 deg f on the average. That's important because it allows you to get your light closer and increase the lumens to more area if your plants. You still need to keep the room with in the proper temperature range.Quote:

Hey Harddon - It's not a bad thing your plants are drinking 1.5 gallons a day but if you keep the temperatures lower and the RH high they would not need to drink as much. Drinking more water gives them more nutrients too. The trick is to balance the environment so they can use up the extra nutrients and process them into larger branches and more buds.
Does the man have the $$$$$$$ to buy a $350.00 light unit????????
