heat question

    question for you guys, so I run my tent in the basement. My temps are getting kinda low during lights out. This is what I did to solve it, I have forced air heating there is a vent in the basement that I rarely open since it doesnt heat the area well. So I took some 4 inch flex vent i had put a 4 to 6 inch cone on it and used some ducting tape to attach the cone to the vent so heat will blow into the tent.

    Question is do you see and problems being caused by this? to the furnace that is

    Get a little electric space heater with a thermostat, and stick it in your tent.
    I've got the same problem in the corner of my garage and just run a Vornado heater when lights are out.

    space is kinda limited so thats why i figured elongating that vent into tent would work best. It works great so far, just wanting to know if it could cause any issue with my exhaust fan pulling air when furnace isnt on? would it be best to leave ducting outside of tent near a intake?

    @UncleBuck you do HVAC right? do you have any input here

    Do you have intake ducts on the tent ? If so make one of them with Ridgid duct and point a small heater at it hooked up to a temp controller. The only thing you have in your tent is a probe. I also put a seedling heat mat between the floor cover and the floor hooked up to the same controller.

    the furnace is temp controlled so there for isnt this the same without using more electricity

    I would direct it to heat the duct but not force it into the duct. Doing so my offset the neg pressure inside the tent. Also heating can drop the RH really fast too, I counter this by having the humidifier and dehumidifier on the same kind of controller. I ran a line from my ultrasonic humidifier into my tent.

    In the end you would be able to control your inviroment via controllers. Veg, flower even come harvest time drying in the tent. Just lock in RH and temps where you want them.

    the vent isnt fully open so im not pushing to much into the tent. so far i havent seen any problems as far as my negative pressure is concerned. im usually very dialed in but I moved my tent to the basement this time. i have a humidifier on the furnace for the whole house that i can control so as long as its not goingto cause an issue with furnace i think this is a great solution

    <---- this is what I was going to say as well.

    it wont cause any issues with the furnace! all its gonna do when the furnace isn't running is suck air thru the duct work, with that being said , I sure hope you don't have any unwanted pests lingering around in your duct work that could easily make their way into your tent with the runway you supplied for them! !

    Do you need to worry about it getting cold at "night time"? In my country, our outdoor plants produce heaps of sticky resin because of the cooler nights.
