We are currently finalizing our new lab at the Australian orchid Nursery and
would like some help with the spacing distance of out fluorescent light tubes
Our steel racks are spaced at 56 cm (About 2 ft for you dinosaurs still on
Imperial) and we are going to hang dual tube 34 watt standard tubes above the
flasks
We are using 750ml glass jars that stand about 15cm tall( 6") as these seem to
be the standard here in Sth East Australia
We understand about the heat from the ballasts and are using grid steel racks
to disperse the heat.
What we really need some help on is what distance above the flasks should we
chain hang the lights?
Is it as close as possible? I'm sure it varies between genus e.g. Paphs and
Cyms but is there a general standard?
Also is there a minimum distance the flasks should be placed above the
ballasts. We will be using oscillating fans to disperse the heat around.
