I too have pay as you go electricity with BG and it is the same cost per unit as if I had a bill come through the door. Shop around perhaps?

check out induction grow lights. They are high lumens and low watts with excellent PAR values @ 300 naometers for veg and 700 nanometers for flower/bud. We've had excellent kush yields with less then 1/2 the consumption of the HPS grows.

Also they produce very little heat and unlike LED they are a wideband distribution which means more light hits the lower branches so the plant does not have to stretch to get light. The buds are tighter. check out the youtube vid on indagro and if you want to see operational cost comparisions there are tabs on the bottom of their home page. peace

Do you know of any actual grows for proof they can in fact flower well, the website only shows me pics of a trade fair and a few chicks in shorts, the video tells me info I could find on wiki....I have looked at these lights for a while now along with LED. I never really see evidence of nice fat colas.

That's what I run right now.. along with a few CFL bulbs that are used for all my side lighting needs.


I just added the 150watt HPS/MH kit about 2 weeks ago.. just wondering what I should expect to pay for adding the HPS kit.

Well I was trying to find out why my bill went up so much, and here is what I found. I have a 150 watt Sun system HPS light combo. Ballast and light together. After doing the calculations I found out it actually is using 384 watts. If you look on the side it says 120 volts and 3.2 amps= 120 *3.2 = 384 watts ouch!! Thinking I should upgrade to a 400 watt digital ballast.

Also I was wondering if anybody knows what the average amps for a 2 light 4 foot T5 takes. I assume that the two bulbs take 108 watts + ballast.

Also for anybody running cfl's look on the side of the bulb to really figure out how many watts, I looked at my 42 watt & 23 watt. Here is the true watts.

42w= 120 volts * .61 amps =73 watts
23w= 120 volts * .38 amps =45.6 watts.

The biggest surprise was my 200 watt CFL it came out at 336 watts.
No wonder my bill jumped so much.
I figured originally at about $30 for everything upon further investigation I found out it costing me about $70 and that doesn't include taxes, line loss and delivery charges.

After reading the thread I had to really show people how much these bulbs are costing.

Any input or thoughts are welcomed

Hi everybody. I'm at my first grow so excuse my cfl's. Will upgrade next time. Had a decision that this first grow will be all about learning from mistakes. Till now I've been vegging with 14/10 lights. Dumb I know so when I realized that I' already flowering I just switched to 12/12 and well see what we'll get. Guess around 1/4 oz per plant with my current setup.

Some help needed:

1. In the attached pics is it a male ?
2. Will NPK 1.5-2-4 be ok for flowering ? I started vegging with NPK 3-1.5-3 and have Nitro burns all over. Just water for now.
3. I have 2 sq foot growing area with 4 plants and 10000 lumens mixed 6400k and 2700k.IMG_5967.jpgIMG_5966.jpgIMG_5964.jpgIMG_5963.jpgIMG_5965.jpgIMG_5961.jpgIMG_5959.jpgIMG_5962.jpgIMG_5960.jpg

So I shouldn't be concerned with what type of lights I use based on energy consumption? Is this due to high energy items like big screen LCD TVs becoming so prominent in homes?

To find the cost to run one item:

1. Total up the watts per day for the item to get total watts/day.

2. Divide total watts/day by 1000 to get the total kilowatt hours (Kwh) per day.

3. Multiply the Kwh/day times the cost per Kwh* to get cost/day.

4. To find out the average cost per month, multiply the cost/day by 30. (Power company monthly billing cycles vary from 28-33 days)

If you want to find the cost of all items:

1. Total up all the watts per day for each item to get total watts/day.

2. Divide total watts/day by 1000 to get the total kilowatt hours (Kwh) per day.

3. Multiply the Kwh/day times the cost per Kwh to get your total cost/day.

4. To find out the average total cost per month, multiply the total cost/day by 30. (Power company monthly billing cycles vary from 28-33 days)

Example: 1 inexpensive regular-sized human heating pad = 50 watts, calculated at PG&Es standard rate, averaged:

50 x 24 hours/day = 1200 watts
1200 divided by 1000 = 1.2 Kwh
1.2 x 0.12 = $0.144/day
$0.144/day x 30 = $4.32/month
