5 girls in a 4x4x7 foot area.
1000W HPS
growing in soil with an oscillating fan on them
using shultz bloom plus.....
Plants all look healthy though they are stretching pretty high for my room since I need 3 ft. of light clearance with a 1000w
I've had to bend 2 of them.
I think the tempatures and humidity are getting too high in the room.....
There is no exhaust fan and I can only vent the room by opening door once a day.....
What can i do to lower temps.????
What can I do about stretching??
at about 21 days of 12/12 only 1 plant is really starting to flower hardcore...
the one on the left is the one that is flowering the best...
Zandor??? HARDDON????
you need your light closer to them to stop the stretching...you have a heat problem...
with 1000w light you are going to have to vent somehow or use smaller lights and that sucks...I don't think you can have enough fans to bring temps down with that light...
Thanks latewood
I think im going to install an exhaust fan. Would it be okay to have it run 15 mins. on....15 mins. off...and so forth. This would bring in more fresh co2 and better my plants even more with temps being down and co2 levels being up....:) My weekend project is set then. Exhaust fan to clear that hot steamy air...yeah baby..
You can help yourself immediately here....to some degree...
Your fan is positioned in such a manner that it is going to suck in hot and blow hot air out the door. You are not getting IN any fresh air.
You need to add a fan and have it blow INTO the room at a level lower that the one you have blowing OUT of the room.
That will create immediate improvements in air flow.
So you need two fans.
One low in...one higher out. That might help keep a buffer for the top layer of heat until you can exhaust out of the room.
Remember though, to exhaust OUT you must also exhaust IN.
HAPPY EXHAUSTING :)
Harddon
thanks much
I have a smaller fan that I will turn on blowing into the room at a lower level....i can see how this might work...thank you very much..
the only thing is that the room is enclosed for most of the day...will the smaller fan by the door still help my cause???
Unfortunately it will not address or solve the issue.
It may provide temporary releif, but, without air IN and air OUT there can be no escaping the heat build up. The only thing you can do is just keep the air moving so much with second fan that nothing will burn or frizzle the plant tips.
If lighted temps. were in the 90's, how much would that hurt my bud production or overall yeild???

I see you talking about removing the reflectors or hoods from lights. Would this help in my situation? I would just put reflective material on ceiling and have bulb hanging by itself...somehow?? If i could drop 10 degrees it would be sweetness under the 1000W er baby :)
well try it, but be real real careful with that light...you evidently can measure temps, so get a temp reading...then remove hood during lights out and carefully hang it back, you may have to make some adjustments to the way your light hangs...just make sure you can still manipulate your light up and down...anyway take temp readings for a day and find out if they are lower...goodluck...if it doesn't work, you only gain experience!
Removing the housing will not help the heat situation. The hood will be gone but the light will still be there, emmitting the heat.
You MUST get the heat OUT of the room...
FRESH AIR IN STALE HEATED AIR OUT.
Perhaps you could install vents somewhere? I saw three brick walls. you could vent the door itself and solve your heat issues.
That is, if you door isnt made of brick too :eek:
Sorry but you need in and out air flow.
As for 90 F temps, i can tell you first had the dangers you face....
EXTRA LARGE FAN LEAVES....
These grow longer to have more surface area to displace oxygen and wastes thru the stomata on the underside of leaves.
This also helps create shade and attempts to lower or regulate the internal temps.
The resulting large leaves will shade lower secondaries and reduce yeilds.
It also increases odds of sexual confusion.
I suspect it will lower THC production but don;t know this to be fact.
But, you can still grow some good weed with it :)
With a light that large you must have a glass heat sheld air cooled hood with a good blower to move cool air thought the hood and out the otherside. Temperature in the 90's can and will turn your plant into a hermie.
Guys
I have a black heavy material hanging on the side where the picture was taken. This separates my flowering room from my veg/clone room.... this is my first run at it..... i have the space to do it....my veg/clone room runs 24/7. all flouro's. i also have a heavy material hanging to cover this room to prevent light from getting in the flowering room during the dark period...I am gone usually when the light flips on so i cannot open the curtain to the flowering room. I am thinking of using a corebit to drill through the brick on the flowering side to make a 2 inch hole. Then install a blower, mounted on the wall, that blows out 15 mins on, 15 mins off during light on period. I will vent/pipe the blower right out of the side of the building.
Would a blower blowing out have to force air in due to displacement??? you would think so some how....
Input please......My girls are sweating to death as we speak AAHHHHHHH!!!!!
How much is a glass cooled heat shield w/fan????
You can get a cool tube for about 150.00 and a blower for about 100-250 depends on what you get. The vortex is expensive but one of the best around.
