Friend of Drknow
The meter is Apogee from http://www.gemplers.com/ I forget what I paid but it's listed there
The numbers are well explained at http://www.sunmastergrowlamps.com/Su...andPlants.html
Check the chart there
And a 40 watt bulb 6" away "IS" alot of light...
I will have numbers on that later
Commercial Propagation Boxes use as many as 4 x4 foot flouros
It's plenty of light but 000 heat....
Does anyone know the temp the water should be for a bubble cloner...
Thanx
