This is the first in a series about the features of my G.A.H.T. greenhouse. In this video we are going to talk about seven ways I cool my G.A.H.T. greenhouse. But not all of these techniques are exclusive to my type of greenhouse. Points 3, 4 and 7 (also 5) apply to all greenhouses.

If you have a greenhouse you know that solar energy can be a double-edged sword. For many people during the hottest part of the year greenhouse is just another way of saying OVEN.

However, the hottest recorded temperature in my greenhouse was 95.9 degrees and that was on a 94 degree day. Also it was only over 90 in my greenhouse that day for about 3 hours.

So how am I able to keep the greenhouse so cool? I’ll mention seven ways, and the first two ways have to do with you guessed the G.A.H.T.

GAHT fan is pulling hot air out of the top of the greenhouse and cooling it 6ft below ground, That cooled air is returned to the greenhouse helping to lower the overall ambient temperature. In addition to the G.A.H.T. system - fresh air intake and an attic vent that is exhausting hot air.
I also can replace windows with screens,

The next three ways have to do with the location shape, and position of the structure.

My greenhouse is located where it get’s shade from deciduous trees in the morning and later in the afternoon when it’s hottest…shade from trees that lose their leaves mean it’s keeps cooler longer. My greenhouse has a wood shingle ROOF. The roof is designed to reject the angle of the high summer sun. In fact during the summer the sun doesn’t reach the back wall of my greenhouse. Lastly the position of the greenhouse. The structure is pointed south south-east by about 15 degrees. This means that during the hottest part of the day the building is faced away from the sun.

So there you have it, 7 ways I cool my greenhouse.

But you might wonder is a greenhouse worth it or even what is the best greenhouse. The fact remains that greenhouse growing is a satisfying hobby, stay tuned to my channel for a greenhouse tour. Once you have a greenhouse you will wonder how to cool down greenhouse because your greenhouse too hot, so watch this video and learn how to cool greenhouse.

a passive solar greenhouse is a great way to manage excess heat. These can be made from old window greenhouse and new passive solar greenhouse construction.
