Spots and more spots

[No-Pro-mwa]

Leafmite I will try and remember that. I didn't have any Dens at the time.

I have also heard copper is not good for Dens. Haven't tried it tho.

I think those are mostly warm growing ones. Especially the Phal type. My winter greenhouse temps are similar to yours but a tad warmer. I keep my couple of warm growing ones on a heat mat away from any cold drafts and in as warm a spot as possible.

I thought I read somewhere that the Aussie Dens like it colder. I do have to balance because I have cool growers and warmer growers all in the same grow space. I am just trying to put the ones that like it cooler near the windows and the warm growers in front of the heater (radiant, not forced air ) where it tends to be warmer, and some of the little ones are on a heat mat. My biggest problem, I guess, is learning which really need it warmer and which need it cooler. I have mostly the Dens I mentioned and several Catts, and then the misc. other genera.
