Cannabis with low electricity costs.

Use HPS.,

CFL's have a lower efficiency,
thus they use more electricity to create the same amount of light.

ditto; the only reason to use flouro's for flowering is heat

can i get something cleard up? is it the watt power that is important about the bulb or the lumens it emits, cus i have these energy savin bulbs that are only 15watts but they give off 900 lumens used to replace a 60 w bulb there just more exspensive then the average bulb

i imagine that's a cfl yo; you'll just need more juice; but yes, lumens is the important measurement


lumens/watt is your efficiency; how much light it puts out for how much power it uses;

HPS is most efficient, folowed my MH, and then different types of flouro: t5HO might be most efficient flouro, but i'm not sure

The lumens are important in knowing how much light you need for your space.

try to keep it above 5000 lumens per sq foot

Watts just let you know how much your grow is going to cost in power.

If you are going to have a largish grow 400+watts. try to go for MH and HPS they will be cheaper in power in the long run.

ALso, Disregard the "equivalent" wattage.

So your bulbs are 15W equivalent to 60W.
Forget the 60W, itâ??s just a marketing tool so that you know which bulbs to buy to replace what in your house. When telling people what your using, use the Actual power consumption

Here is a Thread I made regarding power consumption and the cops.

Today when i was in the store, i was looking for some grow lights, they had the HPS and the ML but they say you need a ballast, the only ones they had there were for a Fl. light, will that one work? and another question, i seen some incondecent bulbs for plant growth, and i was wondering if those would work?

DO not USE INCONDECENT BULBS

and start your own thread if you have questions, dont steal

[whitestalkslongwalks]

92 lumen/watt T5H0's for veg room

140 lumen/watt HPS's for flower room


doesn't get better than that

I use a 150 watt HPS witha 70 watt MH. I get 3-4 ounces every 50-70 days or so. Wiith ventilation running 24/7, this box costs about $20.00 a month to run.

yes this is good id say for you what plantboxer says is good and cost afective

[a-hack]

so for 10 plants(white widow) what would be a suitable amount of light?

[harris7]

I can have one mother plant per adult, although.... we are not allowed to use air ventilation, lighting, ph meters, ....
!

wo, do you mean you can legaly have 1 plant per adult?

thats cool

i guess the ventilation and lighting restrictions are for sustainability reasons?
