Grow Room Power Requirements Calculator
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

Input Values: All input values must be entered below to obtain results.

Number of lights you were thinking of adding Lights =
Wattage per light you were thinking of adding Watts =
Length of room (ft.) Length =
Width of room (ft.) Width =

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.

Input Values: All input values must be entered below to obtain results.

Length of Room (ft.) Length =
Height of Room (ft.) Height =
Width of Room (ft.) Width =
CO2 (ppm) (eg. for 1500ppm CO2 desired, use .0015 as the variable) Variable =
Time (seconds) * use 60 seconds for value Time =
Cu.ft. per hour of CO2 * value located on device Cu.ft./hr. =
