Finished my clone box last night.
2 100W equiv CFL
4" duct booster fan
ductstat temp control
plexiglass door
plastic clone tray
root zone heater (no thermostat for it yet, maybe today)
I basically just partitioned off the space between two shelves and installed the equipment inside.
There is some space left on that shelf and I hope to have a mushroom fruiting chamber

there someday. I just gotta get this

garden rolling good first.
I plan to take about 10-15 clones every two weeks. I can only flower 7-9 per cycle.
Looks like the ductstat from Home Depot Might work fine for this application. I saw it at Home Depot and bought one, then that evening someone posted a link to it in Al B. Fuct's FAQ. It is a little fiddly to set but seems to keep about a 3 degree F spread. I hope that is not too much. At $21 if it works ok it will be a good buy, as the fan plugs right into the unit.
I placed a hygrometer in the box and it has stayed at exactly 20% since I opened the package. I placed some wet rockwool and sprayed some water around on the warm tray and it still never budged. I am beginning to wonder if it works at all. I will double check that with different meter before I use it.
Hopefully I will need this in a week or two.
