So just got a question or two having to do with buying some new equipment / equipment i got. Right now my equip. is 1 13watt 3000lumen 1 23 watt 4000lumen 1 23 watt 2700lumen, a decent fan but isn't oscilating.
So i need to buy some more lights and don't want to buy different lights for veg/flower, but doesn't 6500 lumen put out more electricity? how much cfm for 1-2 plants? I know the higher the wattage the better, but im going to try to make it by with a little less than i should have, but wondering about the lumens. would it be best to just have a bunch of different lumen bulbs or all 6500k (if its not worse on the bill) or what? thanks
First off the 6500k is not lumen output... that's the colour temperature in this case 'daylight' the 2700k puts out 'warm white', you tell how much electricity it will use by the wattage not the lumens.
if it were possible you could have a 10,000 lumen bulb on a 60w fitting and it would use the 60 watts but that would be one damned efficient bulb shame it probably doesn't exist.
Doesn't matter too much if your fan isn't oscillating so long as it's not pointing directly at your plants, make it kinda blow on a side wall so your plants feel the effects but not directly.
As for CFM you want a fan that can replace the air in your room once every 5 minutes so we do a little equation:
Length (ft) x Width (ft) x Height (ft) = Volume (cubic feet)
OR
You could work it out in centimeters and divide the volume by 30 to get cubic feet
OR
You could work it out in inches and divide the volume by 12 to get cubic feet (don't hold me to that I work with the metric system, imperial sucks)
Whatever you work with, you then want a fan that can move that much air in 5 mins
You can work this out, I think, by dividing the cubic feet by 5 and that basically gives you the minimum CFM rating for your fan, any CFM over the maths is good too
LAST POINT! If you don't want to buy different lights for veg and flower try to go with a good mix say 2x 45w 6500k bulbs and 3x 45w 2700k bulbs (in my opinion this is a good mix and will give you a nice yield providing you do everything else right so second or 3rd go round you can be looking at 1 oz+ per plant in a small area : )
And trust me when I say that you can have a fair few CFL's with MINIMAL increase in electricity and I mean not even noticeable I had 250w worth of CFL in 2 chunky 125w units and they cost me pennies a day IF THAT!
thanks for the tips...seen a bug or two the past couple days....tiny one...one had wings..does it matter if its just one or two that you randomly see? i make sure to check the plant thoroughly n i cant even find the one that i had just seen..
