Cfl lighting help


Recommended Posts

i think the real trick here with the 80w is the space of your tent / cupboard and working out the wattage needed with the light calculator and doing a bit of maths :P

 

put it though the lighting calculator - http://cannaversity.com/calculators/lighting.php

 

so 3x3x2 yeah?

 

Your room is 9.0 squarefeet, please review the three levels of recomendation below suited to your grow room 
 


Minimum Lighting 25 watts Per Square Foot

Lighting 
The minimum recommended lighting for your area is 225 watts
Ventilation 
The minimum flow rating of your fan should be 15.0 Cubic Feet per Minute (CFM
Power Requirements 
This setup will require 1.2 amps to be available at all times for safest operation* 

Optimum Lighting 40 watts Per Square Foot

Lighting 
The optimum reccomended lighting for your area is 360 watts
Ventilation 
For optimum ventilation the flow rating of your fan should be around 16.5 Cubic Feet per Minute
Power Requirements 
This setup will require 2.0 amps to be available at all times for safest operation*

Maximum Lighting 60 watts Per Square Foot

Lighting 
The maximum reccomended lighting for your area is 540 watts
Ventilation 
Going this way you will require a fan with a flow rating of at least 19.5 Cubic Feet per Minute
Power Requirements 
This setup will require 2.9 amps to be available at all times for safest operation*
Additional Comments 
Getting to these points and or over it is highly reccomended the grower use Co2 in their room as your plants will only be able to photosythesise a certain amount of light before needing a Co2 boost to benifit
 

you've got 92w of CFL's running -  now here is where you do the maths :P

 

It says on the side of the box what wattage it's equivalent to VS. incandescent 23w = 100w so "Theoretically" you have about 400w of incandescent brightness, but the trade off is power cost & heat penetration, your buds will be fluffier and lighter.

so according to the chart you need 360w, you have 400w

 

although that calculation is iffy but that's what i go by my 80w on the side of the box say equivalent to a 250w :/

the link that Louise posted is exactly what i use.|

Good luck!
