swamp cooler for 8x6 Snap n grow

[Orchidbyte]

Have had this 8'x6' Snap n grow for about 5 years now and the only way I could cool it in summer was several fans and a mister system, they helped but I still lost plants do to heat stress. I started.looking on CL a few weeks ago and I found a very new unit for a very low price, had to buy it.

Outside temperature is 99f and RH is about 25%, inside GH with cooler, 87f and RH 68%, nice.

I have cooler on low cool and that setting works great just the right amount of air flow. If I turn it up to high It literally will blow the doors open. The nicest thing now is that I can walk in without having to move fans out of way, I can go in anytime I want, so cool.

I mounted a fan a long time ago to ceiling to act as a way to draw air up and to force some hot air out, that fan is the only one I use.

I have cooler and fan on two temperature. Controllers

Let me know what you think.

That looks perfect.
I also found a CL swamp cooler since my temps can get really high in the summer. They're great. The plants have done much better since I got it.

I bought a thermostat for mine which makes it even easier.

Nice green house and swamp cooler.

I have a Porta Cool swamp cooler and I find it makes a difference for me too. The humidity is pretty low in the greenhouse in the summer and temps pretty warm and this helps increase humidity and cool it down. I have my less heat tolerant plants located closest to it.

Be sure to add something chemical to the well if the swamp cooler. Without it you'll get mold spores galore. I had that issue with my swamp cooler. Wish someone had told me about it before I nearly lost my gongora. But these machines are marvellous and I could not grow without them in Dallas. You can also lower the day temps more and add more humidity just by adding a bucket with some water and a pond fogger in front of the swamp cooler and get a fun fogg. That brings my temps down as low as 70 if I want to when its 104 out.

Wow! That's great! Glad you were able to get your temps down under control.. And great humidity to boot? WooHoo!

Out of curiosity, how well do swamp coolers work for places like the southeastern US? Like say RH @ 60-70%, and +95°F... For example..

I didn't know this, so thanks. Are there special products? I'll be sure to add something next summer but not sure what.
