My first greenhouse here was 3 feet in the ground because I had an HOA so had to have it "below the wall". That probably helped a great deal but it is expensive to get dug out and retaining walls placed.
Evaporative cooling works well here for sure but has a tough time keeping up when it gets over 110 which is basically all of June/July/August. I have. water all on the back wall and a forced air swamp cooler on the side and still it gets to 90-95 in there. Have misters as well which helps also.
Hi there. I live in Scottsdale and have had 2 greenhouses. My first was 8x8x16 and my newer one is 16x11x30. I am still trying to get my larger one dialed in. Arizona is very tricky. Too hot in the summer and too cold in the winter. And too dry all the time. I would be very interested to...

Thanks to everyone for your input. I do not grow under lights, I grow in a greenhouse in AZ. I increase humidity with misters and control temperature with a water wall and a supplemental forced air swamp cooler. Have added Epsom salts as suggested. Will continue to do so. It definitely seems...

I have not done a pH runoff but went ahead and took it out of the moss and planted in bark. Roots all seemed fine and in fact there were a couple of nice new roots just emerging and a small new growth that appears to be fine. I will just keep my fingers crossed and hope for the best.....
abax: I don't think mine is lack of cal/mag either as I am using MSU fertilizer and reverse osmosis water. I also have given some cal-mag plus recently. My viral test kits arrived today. I'll let you know what they show. The brown leaf tips are actually a bit of burn I believe. I am in...
Hello, I purchased this Phrag Frank Smith which has been doing well but has developed these pale green streaks and I am afraid it is viral or possibly bacterial. I have ordered CymM/Odon Ring virus test kits and are awaiting their arrival. Anyone have thoughts on what this looks like to them...
