Growth abortion and size issues in Lepanthes.

What fungicide did you decide on? Diluting to the manufacturer recommendation is a good idea.

Agreed. I use Physan 20 regularly according to manufacture's instructions. I spray down the backdrop and pots and plants every week or so. I have one 12-volt fan running 24/7 in the case. Case is 36Lx20Wx24H. 99% humidity.

Alright, I'll give it a shot, thanks!

I do the same as Ross when it comes to using Physan.

I use refrigeration fans because I find them more powerful and reliable than PC fans. I also like the fact that they are waterproof.

In my large growing case where all the flowering size plants are kept, I run 5 fans in total. Four at the top (two circulating and two extracting), I also have one fan situated at the bottom of the growing case circulating.

In my smaller growing case where I grow my keikis and leaf cuttings, I have two fans at the top (one circulating and one extracting).

When growing Pleurothallids you can not compensate when it comes to air flow!
