Well this sub-forum came about just in time for me.
I have recently switched to growing many of my Utrics and Pings in covered propogators outside. This has given me huge amounts of extra space but I have a problem with the temp inside the propogators breaking 41 deg C!!! As an attempt at creating a 'shade' I cut up an old shower curtain and stapled it to my patio railing, now I feel there is too little light but the temp is in a much more acceptable range.
Now, I have reams of large bubble wrap and I am wondering, if I decide to use it will it cut the light enough to prevent the massive heat build up?
Any thoughts or experience?
