Hello Brian,

.... need time till August to get going.....

Okay, that explains everything. When do they start into growth?  I had
the same problem but now I use an ordinary propagator to start the
rhizomes in March. As long as they are in the propagator I use small
pots to save space. And as soon as they have sprouted and the leaves
start to touch each other I remove them from the propagator and pot them
up and give FULL SUN. The spring sun does not harm them. If you do that
in your greenhouse you will have a lot of flowers. Now is the time to
start dormancy. 
I also had the problem of plants (not only Gesneriads) not going dormant
in a greenhouse that becomes too cold in autumn. A certain amount of
heat combined with reduced watering is necessary to induce dormancy. If
seasonal plants that normally do go dormant don't, they may be damaged
by fungal disease or produce only small tubers/rhizomes/bulbs. The very
valuable ones I bring inside into a moderately heated room to let them
go dormant there. Not a very pretty sight, though..... but not for

Bye for now,   Uli
