Popcoen Posted June 15, 2020 Share Posted June 15, 2020 Hi All, I wanted to know if anyone may have another way to heat a grow tent instead of using a heater as its killing me on Electricity? I am currently using a 1000watt fan heater which runs pretty much the whole day and evening to keep the temps correct... I have 2x 300 watt led lights which give off almost 0 heat so thats not making the heating any easier... I was contemplating on using a heat lamp instead if anyone has a way around using this it would be a huge help Cheers!! Quote Link to comment Share on other sites More sharing options...
SkunkPharm Posted June 15, 2020 Share Posted June 15, 2020 What us the size of your tent? I run a panel heater on a sonoff wifi switch with temperature sensor. A panel heater only uses 420w. 3 Quote Link to comment Share on other sites More sharing options...
Popcoen Posted June 15, 2020 Author Share Posted June 15, 2020 @SkunkPharm Hi Bud, I am using a 150x150x200 Grow tent. Quote Link to comment Share on other sites More sharing options...
SkunkPharm Posted June 15, 2020 Share Posted June 15, 2020 That would be perfect. Build a frame mount the heater. 1 Quote Link to comment Share on other sites More sharing options...
Popcoen Posted June 15, 2020 Author Share Posted June 15, 2020 @SkunkPharm Awesome thank you so much! Ill look into using that! Quote Link to comment Share on other sites More sharing options...
Ill_Evan Posted June 15, 2020 Share Posted June 15, 2020 Those Sonoff switches are awesome. I'll be setting something similar up in my tent as well. Currently just been using it as a overpowered temp/humidity monitor The extent of insulation where your tent is situated can also be a factor. If a lot of your heat is escaping then an automated solution might end up running 100% anyways. I used to just hang my ducting out an open window but too much heat was escaping my grow room so I built a plywood fitting that went into the gap in the window with a duct flange for my exhaust. Enough heat remains within the room now that I don't need a heater at all at the moment. 1 1 Quote Link to comment Share on other sites More sharing options...
Popcoen Posted June 15, 2020 Author Share Posted June 15, 2020 @Ill_Evan I know one of the issues is that my inline ducting is getting air from outside, unfortunately its the only option i have right now as my tent is currently in my shed. I have dialed my extractor fan to a minimum aswell to try and conserve heat, i just hope my electricity bill wont be outrageously crazy... 1 Quote Link to comment Share on other sites More sharing options...
Ill_Evan Posted June 15, 2020 Share Posted June 15, 2020 Shjo! Conundrum. I suppose one could swap out the LED's with HID bulbs and birdwings so that you're getting your heat and your light from one source then swap back to your LED's in Summer. I only suggest this as it is what I am doing not an inexpensive solution but first thing to come to mind.. 1 Quote Link to comment Share on other sites More sharing options...
Popcoen Posted June 15, 2020 Author Share Posted June 15, 2020 @Ill_Evan Oeff... Ill have to stick to LEDs for now as this is a recent setup. Thanks for the advice!! 2 Quote Link to comment Share on other sites More sharing options...
CreX Posted June 15, 2020 Share Posted June 15, 2020 What are your Temps like? I would only switch a heater on if the Temps are dipping below 15... And your extraction is proper killing your heating attempts lol. I would maybe try only running the night as the days aren't that bad yet. Also you could try reducing the intake of air a bit to try keep the inside air warmer. Your tent should heat up quick enough if the cold outside air wasn't coming in faster than you can heat it 1 1 Quote Link to comment Share on other sites More sharing options...
Popcoen Posted June 15, 2020 Author Share Posted June 15, 2020 @CreX Temps are great if i have the heater tunning, its got a thermostat so turns off at around 28 Degrees C and on at around 20 degrees C, My extraction fan is on the lowest and has created almost no negative pressure which is cool for now as i dont want that heat leaving :( So currently i have my LEDs on a 18/6 cycle, and i have the 6 hours off during the day when its a tad warmer. Should i maybe put my extaction fan on a timer? Perhaps that could help? 1 Quote Link to comment Share on other sites More sharing options...
Ill_Evan Posted June 15, 2020 Share Posted June 15, 2020 If you're in veg and are running LED's there's no reason to not run 24hrs of light. Unless you have auto flowers then I think 18-6 is the way to go. 1 Quote Link to comment Share on other sites More sharing options...
Popcoen Posted June 15, 2020 Author Share Posted June 15, 2020 @Ill_Evan So i have LEDs that have a veg and bloom switch maybe running them both? With the 18/6 cycle (I have autos in my tent atm). Quote Link to comment Share on other sites More sharing options...

But it would need to be some timer, as intake is crucial and cannot be stopped for long periods... Something like 5min on 5min off might help out. But I would adjust your temp parameters a bit. Make the heater only kick on at 15, and it can turn off at 26 28 is quite a challenge for a little heater to reach in these cold times 1 Quote Link to comment Share on other sites More sharing options...

Nah just keep it on veg mode during veg, but keep veg mode on when you flip bloom mode on for flowering. 1 1 Quote Link to comment Share on other sites More sharing options...

With the 18/6 cycle (I have autos in my tent atm). Wow okay thank you! I wasnt sure if anything under 20 degrees would be good... But ill sit and adjust that! Unfortunately my timer is the analog timer so its only in 15 min intervals and i know thats a bit too long with no air moving around. Thanks for the advice tho! I think having it go till about 15 would help me a heap load! 1 Quote Link to comment Share on other sites More sharing options...
Kiteloop Posted June 15, 2020 Share Posted June 15, 2020 @SkunkPharm How big is your grow area? I’ve been thinking about these Panel heater aswell. What was your temp range before you added the heater? Curious to know how much it raised the temperature. Quote Link to comment Share on other sites More sharing options...
GGG Posted June 15, 2020 Share Posted June 15, 2020 Hi@Popcoen, as advised the panel heaters is way more efficient than the element heaters, I put my panel heater just behind my oscillating and the cold intake air behind the heater, I think it helps to move the warm air around better before the warm air gets sucked out Sent from my F5321 using Tapatalk 1 Quote Link to comment Share on other sites More sharing options...

So night time temps are between those. Day time it goes up to 25 to 27 degrees. I regilate tat with the extractor fan. 1 Quote Link to comment Share on other sites More sharing options...
Kiteloop Posted June 16, 2020 Share Posted June 16, 2020 @SkunkPharm you are obviously not using LED then? Nice day temps. I'm running LED quantum board, but cant get the room higher than 20degrees Quote Link to comment Share on other sites More sharing options...
Popcoen Posted June 16, 2020 Author Share Posted June 16, 2020 @Kiteloop Hey bud! What is the size of your room? Quote Link to comment Share on other sites More sharing options...
Kiteloop Posted June 16, 2020 Share Posted June 16, 2020 @Popcoen ive got a section in the garage. Its 1,3 x 1,5 with one side open. I'm thinking of closing this off today and also to line the floor with cardboard to help insulate the floor better Quote Link to comment Share on other sites More sharing options...

It is also connected to my veg tent 1.2x1.2 by means of ducting. So it warms that tent as well. Quote Link to comment Share on other sites More sharing options...
