How about making some kind of mini greenhouse. Use for example an old
aquarrium. I had trouble keeping phals in general till a few months ago.
When I placed them in baskets in my mini greenhouse with the higher humidity
they toke off like they were attached to rokkets. I have flowers in Phal.
equestris, bellina, pulchra and the pallens. The roots are coming growing
well again and I use honney as extra fertilizer. It's cheap and has no
negatif influence on the roots. It's just an extra boost.

Just an idea, I may be a newbie but I experiment a lot and keep on looking
for a better way to grow using as little space as possible and keep them
alive and flowering.
