It's getting hot in here!
 

Even with aluminet 60% it's actually warmer in the mini greenhouse than outside(I have a small fan running). I put another double layer of aluminet on top of the greenhouse to try to keep the temp down; it had reached 89 at one point. I'm going to put together a swamp cooler to see if that helps. Does anyone have any tips? This is all new to me. Thanks

It's new to me too, Mo Boggie. The swamp cooler helps, but it will almost always be warmer inside the greenhouse than it is outside...except at night! Hopefully, by the end of the summer we'll have a better handle on things.

Well, that was fun. I finally got the system up, but I'm short on tube, so that's a drag. It was a nice hot sunny day, so working in the greenhouse was an absolute joy, why yes it was. The sweat was running off me like crazy, and runnig in my eyes at crucial moments, which is SUCH fun.
Then there's wiring in an extra socket, with sweaty fingers and slippery screwdrivers with the blood throbbing in my head.
Yep, all in all a great day. Plus I have the bonus that all that time in the sauna (sorry, greenhouse) should have sweated off a few pounds. I hadn't realised how dehydrated I'dd got till I went to baptise a plant in the garden, and found I was passing yellow powder.

Couple of pints of water and I could almost pass for human.

12:52pm, and the outdoor temp is 99.6. We still have a good hour before we peak out, so I'm thinking today is the day the ice finally breaks on the Santa Cruz River. ;-). We have the regular sun shade cloth, the aluminet, a swamp cooler, and misters, and at the moment the greenhouse is 89 degrees! I just hope there is still enough light getting in for stuff to grow! The humidity is about 61, so in terms of temps and humidity, I'm pretty pleased.
109 within the next week or two!!!

I think that those temperatures are why I live in Ohio. :)

Yes, but talk to me about this again come January.
And remember, when it is hot, like today, our humidity is about 8%. You hit 98, and your humidity is what? 75%?

First, you need a big fan or two, not just one small one. If its warmer outside, then open the hatches and let outside air in!! And 89 degrees is not a problem. Start to worry once you get above 100.

Yes, it gets very humid during the summer. Still, winter makes those of us here love summer. You really appreciate all those spring bulbs, lilacs, and everything else that comes to life when the snow becomes a distant memory.

I am in london ontario and i have 4 fans in my greenhouse and 4 vented slots for exhaust and inner flow , but it seems to be too hot in my 8 by 8 , i still have my orchids under lights in the basement and still scratching my head wondering if i should pass on the greenhouse and stick. With a better controlled enviroment , but this fogger thing sounds intresting , just wonder if i could find one in ontario?

Meh, It never gets too cold here, though it does freeze at nights in Jan and Feb, tho if you get up late in the morning, you'd never know.

Even with that spring is still great with masses of wild flowers.

You don't need a hellish winter to appreciate spring.
