So I went ahead and topped the male, A.K.A. "Dude", I locked up the top and set him into flower. But as a Plan-B I kept the bottom and put him out in the living room to finish away from everyone. Then incase I totally screw up I took some clones from way down low and have them in veg. Think I...

Heres my currently passive system, Cool air in from down low. Hot air up and out. CoolTube as-is, is closed. The room itself has a cold air intake (not shown), and a 4" T above the HPS for heat exaust. When my $35.00 total/4" inline/240cfm fan arrives I will connect the light exhaust to the room...

But my main question is will a male mature/drop pollen under an 18/6 veg cycle.

I a have a male "21" with strong genetics that I am trying to collect pollen from to play mad scientist with. I chopped the top rooted it and contained him to prevent uncontrolled pollination of my ladies. I kept the bottom half incase I kill the top before I get pollen. I put the bottom in the...

Well without enough expert advise I have choosen to exhaust my light and flower room into the laundry area with a great diy carbon filter design I found on Grasscity. My damn camera eats batteries so I am behind on getting my journal started, but I have three ladies into flower and will be...

So I saw on a thread that you HVAC knowledge I was hoping you could tell me if it would be safe for me to tap into my furnace exhaust using a 45 deg wye and placing a backdraft damper where the duct exits the flower room. I have a thread going with a pic of the furnace area, if u want just do a...

The round duct is the exhaust and connects to a 8-10 inch main vent leading to the roof behind the drywall. The rectangular ducting is the cold air return and the main heating duct run. My original plan was to use the 45 deg. wye just before the elbo that connects to 8-10 inch. main vent in...

well here is a pic of the furnace exhaust as it is now. Any ideas comments anything about my plan of tapping in

Stopped by homers and got 6" to 4" fitting for the cool tube. 25' of flex duct and priced the wye, only 10.00. Noticed a back draft damper for a dryer for 6.oo and thought if it was back right after my fan, at the end of the vent run before the last 2.5 ft. of duct that taps into furnace exhaust...

Just checked the basement area and this place is cheap, my only access to the outside is the furnace vent. So any advise on a safe way to use the furnace or suggestions on threads to doing a closed system I suppose. Thanx

Yeah screwing up the exhaust of the furnace has been my biggest concern. I live in townhouse apt. so sorta limited to how far I can remodel. I am a red card holder so keeping the rooms cool is more importent then smell right now. Might see if keeping cool tube on dedicated duct pulling from...

Sub I hope your still checking this thread but I could use your HVAC knowledge. Is there a safe way to use my furnace exhaust to vent out my cool tube

I have limited venting options, is there a safe way to untilize my furnace exhaust

So keeping the fan on, keeps the air flow going, preventing dangerous exhaust from the furnace from leaking back into the grow room duct. Am I correct in my choice of using a wye fitting to tap into furnace duct because it acts as a sweep directing the air up and out?

I was afraid of this. I suppose I'll check out diy carbon filters and vent under the stairs. Any other suggetions or advise dealing with original thread would be helpful.

My Grow area is right next to my furnace venting going out to the roof. Can I use only a wye fitting to tap in, or do I need to put a backdraft damper in to prevent exhaust leakage back into the grow room when the fan is off. I am on a shoe string budget and am trying to save $$. I would make it...
