@Breezy I’m right down the road just south of New Braunfels. I did a grow in the garage towards the end of last summer and I barely made it. Struggled to keep temps under 85 even running an ac. Made the whole damn house smell magnificent if you ask me but my wife strongly disagrees lol. My second attempt was in a upstairs bathroom and it went rather well. Unfortunately I don’t have an extra room in the house anymore but I do have a very solid well constructed 12 x 16 shed. It’s working great for the winter but you know. Hopefully I get it all insulated before the summer time hits.
@MeEasy the unit that I have to do the heat and ac is a portable unit on wheels. If you want heat you turn it around and it blows the cold out and ■■■■ versa for cold. It also has a dehumidification feature and I will say it did work well on my 2nd grow. I was thinking about one exhaust in the high point of the ceiling with a large inline carbon filter. Possibly 2 smaller dryer type vents down low hooked up to maybe 4 inch fans for fresh air intake if needed they could be ported into each tent.
Does “fresh air” have higher co2? I’m assuming so and would like to also have the option to cut the heat and ac when temperatures allow for it.
