High Tunnel Heater

  • High Tunnel Heater

    I have a 16′ x 24′ growers solution high tunnel. With the incoming frigid Temps I will need to have some type of supplemental heat to keep the inside of my high tunnel from freezing. I have homemade end walls and roll up sides. Would a small propane heater provide enough supplemental heat without harming my plants and citrus trees. I’m located east of Raleigh, NC. My main concern is that the fumes from the heater will depleat to much oxygen, causing the plants to suffer/die. My high tunnel is drafty even with all the doors shut and sides closed.

    I’m outside Fayetteville and use a 3-cone ventless LPG heater that has a thermostat it works well set on low.

    only thing I would recommend Keep a watch you gas level and have a fan inside the high tunnel to move the air around

    The heater will actually increase CO2 which will be a big jump in growing power for your plants. Think of it like Nitrous Oxide on an engine the comparison is very similar.

    Like Big Kid mentioned you’ll see an increase in CO2. You have to remember the plants don’t breathe oxygen they release or exhale it so to speak. The plants breathe in the CO2.

    Plants breath in the Carbon dioxide we breath out, they produce the oxygen we breath in, you won’t have to worry about the heater depleting oxygen for your plants.

    We live in Macon County, a few hours west of you. We’ll be getting single-digit temps this weekend. Our 16 x 28′ High tunnel needed the windows cracked a few inches to allow the “Big Buddy” LP gas heater heater to continue to work.

    We switched to two oscillating radiant electric shop heaters that allow us to keep “buttoned up”. (We don’t have roll-up sides.) We still only get a few degrees of added warmth, though, and lost some of the less cold-tolerant plants.

    Good luck!

    Hi guys! I’m new to all this so please excuse my ignorance. I have a very small 8×13 greenhouse. During the freeze (8 degrees) my little greenhouse stayed around 50 degrees. I used 2electric room heaters and “lowered the ceiling to about 4 foot. I picked my first broccoli Saturday. ❤️
