And makes it easy to move plants around to find where they're happiest
with the light/heat/etc.

I haven't tried it, but I can't see the water will be less stagnant -
just be less visible and harder to change...
And harder to isolate and treat any problems of disease or infestation.

I have to confess to not always being as organized as I'd like to be -
I've got some trays that should have been swilled a couple of months
ago, but the plants show no ill effects - in fact they're bursting
into life in a most satisfying manner. Outdoors I don't change the
water, just top it up as it evaporates - it doesn't go stagnant;
indoors on windowsills the trays get a bit rancid within a couple of
months - faster under artificial lights in closed terrariums ( I do
change them at least monthly to stop mould. ) I use a horticultural
water filter and change the filter frequently to prevent salt/chlorine/
lime buildup, but the plants show no sign of disliking algae or
stagnant, scummy water.
I guess a lot of CPs are used to stagnant bog-water - it's more of
a problem for people living in the house when it starts to smell:
*then* you know it's time to change the water <g>
Of course, YMMV, but for my money poor ventilation, mould and chemical
contamination are far greater evils for most CPs.
Hope this helps,

happy growing,
