I find that liberally coating the insides of the windows

Alternatively, a handfull of gallium crystals in a pail of

that method though!

Good luck

Whatever you're referring to, gallium isn't it (it's a rare and
expensive metal, melts in your hand but boils at 2400C). I can't
imagine a handful of any crystals in a bucket of water being
effective. A saturated solution of say calcium chloride in water will
lower the relative humidity to around 35%, but I wouldn't recommend it
for greenhouse control.
