John, Thanks for posting this Info.
Martin, Thanks for bumping.
I have been looking for a better method for summer rooting (less Labor) than the one I currently use (from last season, Dan_LA summer method). I had seen this method in passing used for house plants, and had actually dismissed it.
The Forsythe pot in combination with the Summer Method looks like it would work, for summer cuttings. With the "summer method" 1 inch of water is maintained in the bottom of a bottle, and the cutting is kept in the humid environment (bottle) with the growing tip above the top of the bottle. I have been very successful rooting green cuttings this way, but the bottle has to be shaken at least twice a day to get the cutting wet (above the water line and aerate the water), and you are limited in the amount of cuttings that can be placed in each bottle (although I use a vase instead of a bottle).
Thanks again for posting, I will be trying the forsythe pot this summer.
