Watts or Lumens?

[Whitemare]

How do you guys mesure the amount of lighting?

Is it whatts or lumens?

and about how many of (either) would you need to support 14 plants?

Dose anybody know where to obtain mylar in the US? or are there any other reflective materials here in the USA that work well? I know tinfoil is a nono.

thanks for any info! I really appreciate all the help!

Most HID lamps use about 75% of there watts to get up to illumination temp. Lumens are more the light intensity the lamp produces and par watts are the number of watts that the plants acually use. 1500 lumens per square foot is the average intensity growers are told to use from my reading. The dull side of tin foil is not to bad but mirror like surfaces absorb the light. Mylar is easy to come by at any grow shop. You can order it online at ww.wormsway.com but they are not open today, as I tryed calling them when I woke up. Personally I prefer flat white paint.

Remember if you need to be concerned with the amount of electricity you are using so you don't start popping breakers. Use the basic formula
"Power = Electromotiveforce * Ampres" to find what an item uses.
rearrange the formula to :
Ampres = Power / Electromotiveforce.....so If my light is 400 watts, and operates off of a 120 volt outlet.
Ampres = 400 /120
3 1/3 Amps
Just thought this might be helpful to ya too....

I'm not worried about the power compnay..or anything of the sort. or popping the circuts. been there done that. ( not with the plants..but with a vaccume cleaner --.--)
the only thing I'm worried about, are my plants. who were (mabeys still are) in desperate need of more light. thought I bought anotyher set of lights 2 days ago and have seen a significant amount of growth since then.

I was told on another forum that using Floro lights is fine for the entire indoor grow. I just have to switch the light-color spectrum. ( or something of the sort)

I refuse to buy a HPS system. I went and looked at the equipment at a local Farm & Fleet.. and I'm NOT paying $30.00 for ONE lightbulb. I dont even want to imagine what the ballast + other shit would cost me.
I'm a poor white girl living with her finace in an inherited farmhouse:stoned: we dont have a whole lot of money.

so right now I have two florecent lights or 4 48'in bulbs on 14 plants.
Thats either 160 watts, or 7600 lumens.
is that enough?

I will be picking up mylar, however it more than likely wont be until saturday. I wont buy it online, I'm sick of buying things online. shipping as astronomical. so I'm desperately seeking greenhouses and plant nurserys that sell mylar in my area.

You can veg them under them for a couple of months but they will need a higher intensity light once they get bigger or go into flowering. If you want to cut down on cost flat white paint works well. I would use the mylar money for a bulb.

I personally would use a higher intensity light for the flowering, though I hear though that the CFL will work for the whole cycle. You'll get denser buds with more light, unless the temps get too high.
