New Grower CFL Lighting/Closet Ventilation tips??

[sylviedoee]

Sadly, this girl is ballin' on a budget. Just got five fems in, 4 are autos.

I currently have two CFL's, one 2700k and one 6400k. I have a little 75w bulb in a heating lamp for back up. Is this sufficient?? Trying to get max yield with what I've got. Any tips on these??

Also, being my first grow, I'm trying to figure out ventilation and such. I starting germinating two seeds yesterday, and I'd like to know how much time I have to get my vent system up and running. And the right way to vent for my set up here.


Super open to tips of any kind!

How many wafts are the cfl? What size grow area?

You might consider adding reflectors to your CFLs. If they are just hanging, like in the pictures, the majority of their output is going up and out away from where your plants reside. Properly directed light with a total minimum of 5,000-6,000 lumens per square foot or plant would be a good target. Also, depending on the wattage (heat output), they need to be from 2 to 4 inches away from the plants to be efficient.

Regarding fan requirements, I've compiled the following information that may be helpful...


EXAMPLE FOR PICKING A FAN FOR YOUR GROW AREA:


Your grow area measures: 5 feet long... by 5 feet wide... by 7 feet tall.

Step 1) Calculate the volume of your grow area in Cubic Feet
(Example: 5’ X 5’ X 7’ = 175 Cubic Feet)

All fans are rated by how much air they can move. Their rating is in cubic feet per minute (CFM). The minimum goal is 25-30 complete air exchanges per hour. Some growers target closer to 60 times an hour.

Step 2) Calculate the required rating in cubic feet per minute
(Example: 175 Cu. Ft. X 30 times/hour = 5250 Cu. Ft. per Hour divided by 60 minutes = 87.5 CFM

[FONT=&quot]Based on the above calculations, you now know that you need a fan that moves AT LEAST 87.5 CFM and up to 175 CFM.
