here here !!! my little 2 pence added to that would be that the longer veg would also mean that the plant is a little more mature and ready to be turned into a lady

Mine will all be clones so technically mature but I know what you mean ;-)

They'll be in the cloner for about 2 weeks and then under a 600MH for another week or two so they'll be getting 2-3 weeks veg time between rooting and flowering depending on how long they take to root.

hey dez i learned a little something about lights ol'country has a hortilux[eye super hps] on one side of his 4x8 tubs & a off brand bulb on the other the eye hortilux bulb clearly grows more & better bud than the other bulbs im gonna upgrade my shop has the eye hortilux super hps [spectrically enhanced] for $85.00 out the door it will pay for itself in one grow im still using some brand-x that came with my 1000w. when i bought it hopefully this weekend ill upgrade

hey - whatever it takes bro.... I hear you.

Any good suggestions on how to cool a tent other then centrigular fans. Is there anything that regulates high and low temps? I have a 30 degree difference between lights on and lights off. In a basement in Michigan. I dont get why its running so hot.

B DUB · Feb 17, 2011

I have 3 fans setup by the way. Two on the way out and one bringing air in.

Unfortunately the only thing I know of would be to set up a thermostat with a range and connect the signal wires to a switch or contactor that would control a heater and/or extra exhaust fans. If it were me doing that, I'd set a heater outside the tent but near the intake. Then when the thermostat signals the heater to turn on, the intake fan will be pulling in warm air and when the heater is off the intake fan will be pulling the ambient air. That should keep things from getting too cold during lights out and your light should be able to keep the tent warm during the lights on part of the cycle.
If it's getting too hot, try to kick up the rate at which the air is being exhausted fom the tent.

Are you running an air cooled hood or an open reflector?

I'm running one generic 600 and two sunmaster 600 HPS bulbs that have an 'enhanced spectrum'. The 1000w is running an Optilume HPS that's supposed to be pretty good. I'll keep the bulbs I've got until I get another harvest or two and then I'll be switching to either some Hortilux Eye HPS bulbs or some Sunmaster pulse start MH bulbs. They're available in many different color temps and are supposed to kick ass over a lot of HPS bulbs.

$85 out the door for a 1000w Eye bulb is a great deal BTW.

I have a 6" centrigular pulling air out of the lights. Then I have a centrigular pulling air out the scrubber and then I have one pulling basement air in the tent to get some colder air. I am ok with the temps at night I am really concerned about the 95 degress that the tent runs at some times during the day. It goes down to 64 degress at night.

Dezracer · Feb 17, 2011

Oh, okay. 64 isn't bad but I understand your problem now with the 95 during the day. Keeping them cool is usually the hard part for anyone, myself included. All I can say is that other than running A/C, you're only options that I'm aware of is to run higher CFM fans or try to run your filter as an actual scrubber instead of running it in your exhaust duct. Filters reduce a fan's efficiency by 10-20% depending on the fan and filter so by using a fan to pull the tent air through a filter before exhausting it you're reducing the CFM of air being exhausted which will make it harder to cool the tent. I don't run filters in my tents at the moment and run the filter on a pretty high CFM exhaust for my entire room. This keeps thetemps regulated very well inside my tents.

You might try disconnecting your filter just for a day to see how much it helps to simply pull the air out unrestricted. If it gets you where you want to be, you then know you need a bigger exhaust fan. If you have no choice but to run the filter inside your tent for odor control, pursue a bigger fan. If you can filter the air after it is exhausted from the tent, set it up as a scrubber next to the tent and scrub the air in the basement.

I wish I could be of more help but that's all I got. There is a few guys on here that might be able to help you further if you need it and I'll let them know about your question and ask them to check it out here. Check back here to see if they've got any suggestions that might be better than mine.

I hope it's a simple fix for you.

Dezracer · Feb 18, 2011

Out of curiosity, what CFM are your fans rated at and what wattage of lighting are you running?

nice set up dez scribed doin a scrog myself. hope it looks as good as yours

DST · Feb 18, 2011

Hi B DUB, in your description I notice there is nothing explaining where the 6inch fan pulling air through the lights is going? IF I was to hazard a guess on your system, I would say if you can get the exhaust from this out of the basement then you will be sorted. It sounds like your exhaust from the light is heating up the basement. If you are then just pulling this hot air back into the basement then your temps are just going to sore.

Can you explain how this works, I may be off the mark but that is the only explanation I can think of. Also how many lights and wattage?

yeah i have to say the same try shifting the scrubber out of the line. if your venting into the same room thats most definately going to cause you problems. mould will form fast if your recycling the air.

subbed Dez! nice scrog

Okay so let me explain setup. I have a total of three centigular fans and two air blowing fans. I have 2 1000 watt HPS bulbs and 1 67 = 300 equivalent bulb. I have two centrigular fans pulling air out of my tent. I need to tkeep a 5 x 10 x 7 tent temps under control. 2 fans pulling air out of tent. 1 through the lights and one through scrubber. Then one fan pulling air from basement which is quite a bit colder into the room. Does that help. The one pulling air out through lights ends at light number 2 cause there is no vent on that side of tent.

Dezracer · Feb 19, 2011

Two 1000s create a ton of heat so it'll be a bit of a battle for you unfortunately. I still say take the filter off the one run and see how much that helps since the fan will be able to pull air out faster.

Th other thing you could do wold be to try and figure out a way to get the run with the lights in it to pull that cooler basement air through the lights instead if the air inside the tent that is being heated by them. The lights will run cooler which will help things a bit. I know you said there's no vent on that side but there's got to be a way to get it. I'm not suggesting you cut your tent but some people do cut a 6" hole and run a duct out that hole so the air goes straight through the lights and back into the room the tent is in.

Do the temps in the basement get warm towards the middle or end of the lights on part of the cycle? If so then Don is on to something. My tents exhaust into a 10x12 room but that room gets exhausted to the outside after the air is deodorized. The exhaust for the entire room is what helps manage temps in my case but I still run my lights at night and have the 12 hrs of dark be during the day. I recently installed A/C in the 10x12 too but it's mainly to prepare for summer months and the units have not needed to turn on yet. My temp monitor says it hasn't been hotter than 78f and I set the A/C at 80f. I'd like to run the room and tents at about 75f but I don't want to commit to the extra electricity right now since I'm already burning three 600s, a 1000 and for veg there's a t8 flouro that's almost 200w. There's a few fans running too ;-)

.

Good luck and keep me posted as to how it works out.

Thanks for the excellent advice. Seems like your exactly right. My basement actually stays pretty cool. One other thing is my two fans pulling air out does empty outside so maybe I could get rid of the scrubber.

Attached are pics. I did cut a hole tonight with razor blade. One question I am now running into is light will now be coming in the side of the tent through this hole. Keep in mind I have cooled hoods so they have glass and if light is coming through ventilation I might have some re veg issues?????? Anything you guys can think of that will allow air to flow free enough but block any possible light?

Dezracer · Feb 20, 2011

All you need to do to block light is put a bend ot two in the ducting and the light wont be able to get past the bends. The light that gets let through the ducting will be minimal and there are lots of people that run there's just like yours. If you're concerned about it though you can paint the inside of that duct flat black or get a second flange and screw them together so you can have another piece of ducting on the outside that hangs down.

Good shit Dezgracer. I have actually just hung a pair of shorts over the edge of my tent and the air pull is keeping them in place. Works and the tent seems to be running much much cooler. Give you rep again if I could.
