Great looking tunnel the best shade cloth is a whit or a cream coloured don’t use green it reflects about 50 to 75 % of the Uv rays , plants that grow flowers respond to the lighter colour better .
Night time lows are hovering around 32° now...I'm excited to leave them out there...I got a govee wifi temp gauge...I will watch it tonight and may leave em in the tunnel till fall... :)
Have you had any success leaving them out in 32 degree temps in the past? I was taught anything below 50 can hurt/kill the plant
I have some thermostat controlled fans for exhaust and fresh input...still tinkering with the air exchange / temp controls...
The air flow was always a problem for me. I ended up reading up on greenhouses and the pros do like an air exchange every 30 to 60 seconds. It gets hot in those greenhouses.
I will be upping the air exchange, as I know what I currently am running will not be enough for hot summer weather.
No I've been bringing them in everynight...once I see the temp is about 40° they come in for the night...
That is what got me. I had 1-4" and 1-6" exhaust fan in a 7' x 15' hoop greenhouse. I was blown away by how hot it would get. I has the larger fan set up to come on at 78 degrees and in the summer it pretty much ran from sun up to sun down by the water in Cali. I basically had a grow that got too hot from the heat. Lost the smell. That was when I started reading about commercial green houses and stuff. Are you going to do light dep?
Heat will be a continual issue. I will get more fans...I put in about 600 gallons of water tanks (multiple tanks from my hoard) to act as thermal storage to get me through this spring freeze...I wonder if it will also help absorb /disapate some of the extra heat in summer...it's all an educated guess :)
Wow nice and big what a grow area well done .
Thank you, fumbling my way through :)
Looking good Ben I sadly lost my Polly tunnel in last years fires although it wasn’t set up as a grow not legal in Tassie as yet it was my vegetable production seedling area I had 6 x1000 lt tanks set up and yes they work both ways passive heating and cooling , I’ve got 2 new one set up ready to plumb into ,1 rain water off house roof ,2nd one set up to take our grey water which I use in my organic garden , I really dig where your heading which our stupid laws change real quick and we can enjoy growing great strains freely good luck if you don’t mind I’ll keep a eye on what you up to . Regards OD.
