for years i wanted that clw 440 with the tubes on each side, but none of the shops around me carried it. i wonder what bulbs they used? how long do you think it will be before the arcadia bulbs start to deteriorate the plastics & fibers in the tent?
They use 2ft Solacure Flowerpower bulbs which is the strongest UVB bulb with the right UVB to UVA ratio. At least 5 times stronger like reptile bulbs and their spectrum reach down to 285nm. That means 1-2h are enough and more would damage the plants already. Reptile bulbs go down to ~290nm and to compensate that you need just more time.

μW/cm/h multiplied be 0,036 gives you kJ/m². Lets say you have 6h with 100μW/cm² measured on the meter. Thats 600 per day x 0,036 = a dose of 21,6kJ/m². With only 3h it would be 10,8kJ and with 10h á 100μW/cm² the dose would be 36kJ/m². You only have to remember the multiplier 0.036...
