30w fan * 24 hours
+
5w pump * 24 hours

=

.88p



250w hps * 12 hours = £3.15


150w dehumidifier * 10 hours = £2.52

Total:
£6.55 per week = £52.40 over 8 weeks £32.24 without dehumidifier.

Wow puts things into perspective - im running 2*600watt, 6" fan, 3" fan, 2 pumps... desktop fan........
Anyone got any ideas how high your bill goes before they report you to the cops for unusual electricity usage??

Not sure if anyone has mentioned but unless your running a digital ballast this could add another 10% or something to your hps / mh light.

I've been working this out myself just recently and was quite amazed at the results. Let's see if I can get it right;

1. Electricity- First 3 weeks 96 watt T5 x 24/7 @ £0.15 per K/WH
= £7.26
Then 14 weeks 96 watt T5 24x7 @ £0.15 per K'WH= £33.87
Plus 14 weeks at 1200 watts 12x7 @ £0.15 per K'WH= £212 ( 1x600w 1x250w pls fans etc)

2. Substrate- 5x11 Litres of coco @ £6.00 per 70 Litre block= £6.00

3. Food- B.A.C coco nutrients- Bought 20 litres of A and 20 litres of B for £20.00 Application 2mls per litre A and B works out at 10 000 litres @EC .8. The strain is Nevilles Haze so thats plenty good enough.
80 litre rez £0.02 per litre =£0.16 per fill. For the sake of argument, a plant say drinks 240 litres in 120 day life. Thats £0.48 per plant@ 5 plants = £2.40.

4. Harvest- Five plants, all from seed so times ranged from 77 days to 120.
First plant came in at 140 grms @ 77 days
Second plant came in at 160 grms @ 98 days
Third plant came in at 250 grms @ 120 days
Fouth plant came in at 280 grms @ 120 days
Fifth plant came in at 330 grms @ 120 days
So, thats an actual harvest of 1160 grammes, plus I got pickings for a good 6 weeks too. Also I think it's important to include that as plants were harvested I was able to put a new one in it's place. Over the 120 day cycle, that allowed me an extra plants worth of photons, exactly 17 weeks. The average weight of one of those plants is 280 grms. So actual 1160, projected is 1440= 51 ounces in old money.
So that's £ 224.27 for 1160 grammes =£0.19 per gramme actual
£0.15 projected.
Hope I got that right, it's late and I'm burnt out. Just goes to show what's possible without all the hydro hype burning our plants and our pockets, lol.

ps forgot to say im on 18/6 at the moment

[Bigred85]

It's hard to know without saying how long the rad is on for. Without it I would say it's costing you about £20 a week. If you have it on for say 6 hours a day, while lights off, at 15 pence a K/WH would be another £4.50 or so a week.
But without the actual electric cost to you, it's really just a guess. Hope it helps
