Steve,
Here in hot , Auckland New Zealand, I find that large amounts
 of water helps, 
Growing JI's in polythene bags or pots [plastic or terra-cotta] 
standing in the water.
Ten or twelve inch pots in bins of water or on the marginal shelf of 
my ponds,
The water level is up to 11/2" above the base of the leaves.
with acid soluble fertiliser in the water at very regular intervals, every 
week or two, and shade for half a day the grow very rapidly and 
make very tall flower spikes [up to five feet] 1.65m to is the best so 
far. Also with the heat in summer and what is a very mild winter I get 
good growth and increase with the JI's in water all year round.
