    Wish I knew the answer to that one, because it happens often to me too.


    In any event - I think you are going to have a good grow - those seedlings look like their ready for it!

    So I have installed a 4" inline 200 cfm exhaust fan inside the grow tent. I have it on its lowest setting and am getting slight negative pressure inside which I'm happy with. I am using a 6" passive intake and so far so good. I'll let things get settled inside and get some temp/humidity readings soon.

    I started germinating 5 NL#2 x Chem x OPG this weekend. Three are up, one just germinated and one has yet to pop. I believe I mentioned this above, these seeds were freebies from Seed Boutique. A picture of the bag seed at about 12 days and of the NL#2 cross seedling. Oh, and it seems my pictures often show up rotated...how the heck can I correct this?

    I forgot to mention, with your tent being inside another growroom..make sure you check from inside the fully closed tent and inside lights off, if light travels through the airvents. You might have to build a better light trap then whats given to the tent or you might end up with hermis in your flower room..thats if I'm right assuming you use the tent for the mothwrs and clones.

    Thanks for the pics. I thought there was something funny. I didn't realize you grow inside and outside your grow tent. I think all you need is another fan like crazy chester suggested too. Maybe a bit stronger cheap inline fan which you just run without filter to move the air out the top of your tent. And then cross fingers and toes your humidity is ok. That would be a lot cheaper than an ac. Let us know how you go

    You'll get it done one way or another. I actually don't think your temp is that big of a deal in any event. I'm more worried for you with the humidity - hopefully that big 1000 watter dries the room out sufficiently if you are not using a dehumidifier.

    Chester, you even gave me a diagram! Well done. I'm gonna give the fan inside the tent, like I mentioned above, a try first. It's a very easy thing to try...I'll have the fan and some additional ducting arriving tomorrow so I will know soon if it does what I need it to do.

    How about this?

    You can use two 440 CFM fans - one hooked up like you've done already (but without the carbon filter and exhausting straight out of the room into the unfinished basement).

    The other fan can be used to exhaust the entire room into the unfinished basement. I think the rest (venting of tent) can be done with passive intakes/exhausts.

    I'm thinking something like this:

    Ivan, I'm glad you confirmed what I was thinking here about the fresh airflow into the tent. I have an inline fan on the way that pulls around 200 cfm. I will pull air out with the fan and have a passive intake to bring the fresh air in. This should work. Thanks again, I think I'm getting close to having this setup ready to go.

    Ivan, I think you are right. I had 2 long time growers help me with this build and I think airflow in and out of the tent was just not thought of. I should have questioned this with them. I put some seedlings in my tray and dome propagator last night in the tent and I think this morning I am seeing some white mold on the stems. Must be because of the lack of airflow. Here are some pictures:

    Hey Jerry, I thought about it again and again.
    I think you made a mistake with your air ducting set up here. To me it sounds like you clean the air inside your room with the carbon filter, rather then the air from inside your tent on its way out. And in the pic it looks like you have nothing sucking the air out the tent either. Correct me if I'm wrong. Can u make another pic of the fan and filter and its pluming?
    If thats the case,you might just solve the temperature issues without any other gear.

    What if you placed one of those commercial portable ac units into the 9x13 room, and:

    1. Vented the heat from the ac unit to the outdoors via insulated ducting through the wall (but away from your outdoors air intake);
    2. Vented your air intake to the ac unit from the coolest driest part of your house (or nearby outside the house); and,
    3. Constructed a box, maybe even a tote, filled with salt or other dessicant that is placed either at the beginning of the air intake or between the end of the air intake duct and the ac unit. That way the ac will only take in and give out air that's dryer than the outdoors environment.

    Long term, if you have access to a backhoe and can do what you want on the land, you can dig an area out big enough to coil some of that black drainage tubing (I think it's 6" to maybe 8" in diameter) and bury it at least four feet deep, where the land keeps the temp at a constant 50-60 degrees. Leave the two ends of the tubing out of the ground to use as air intake and air supply ends and place the intake at the coolest place on your property and the outlet at the dessicant box. Then the ac can only draw air that's both cooler and dryer than the ambient environment to pre-cool and dehumidify the air that the ac cools even more before exhausting it into your 9x13 room.

    In the winter, if it freezes where you live and the humidity plummets, you can replace the dessicant box with a wet towel that wicks water up from a tub and run only the fan on the ac unit. That way, you can heat your basement room up high enough, with the help of your lights and humid enough for happy winter plants.

    But, you REALLY got to have the DIY bug bad to put in a passive geothermal cooling/heating system!

    Ivan, the fan is above, just outside my tent. It’s drawing air through a carbon filter, through my HPS hood, into the tent, through my LED hood, out of the tent and pushing the air out through an outside vent. I think Chester might be right, my main issue may be lack of fresh air into the tent. I’m still learning the new setup but I’ll get it dialed in eventually. Appreciate the comments.

    You’re right Ivan...it would pull out the humidity. I may have to pull some AC in. We’ll see how it goes.
