Sharp Rubber Duck, Grow Room Power Requirements Calculator

Q. How many lights do I need in my room?
A. For optimum lumens, you should have 20 (min) to 60 (max) watts per square foot.
Formula:
Square footage (length × width) of your room × 20 (wattage)
= The watts needed

Example:
10' (length) × 10' (width) × 20 (watts)
= 2,000 watts = 2 × 1,000 watt bulbs for that room

Optimum CO2 Calculator
Q. Why is it better to have more Cu.ft./hr. if using CO2?
A. The faster you achieve your desired CO2 levels the better. The room gets less heat (exhaust fan comes on faster) with higher Cu.ft. per hour of CO2.
Example:
A CD36 CO2 Generator achieves 50% faster CO2 then a CD18 Generator.
