ok, i have a 250 watt HPS that i haven't begun to use yet. i want to know a rough estimate of the electric bill increase if possible. about how much did you bill go up by? tell me if you don't understandwhat i mean because i had some trounle tryin to word this.
I use a 600watt h.p.s 24/0 and at most it has added 5 uk pounds a week, So a 250 watt should use far less i think Dont if thats any help for ya
thats not what i meant. i meant that with 18/6 there might be a risk of the plant turning hermie because of light leaks. i know it was off topic (sorry)
Unless you're running 2 1kw lights, there won't be a huge jump in your power consumption... If anyone has a room that uses 5, that's a phenominal increase, would be better to just aim for outdoor season.
unless the light leak is brigth enough 4 u to read a newspaper by then dont worry about it. only worry about it during flowering.
find out ur electric cost per Kw then x by 3 to get the cost per day for 12/12 and 4.5 for 18/6 mine costs 7p so its 7x3=21p a day. 21x7= cost per week 21x30=cost per mth 21x65=£13.65 for the whole of the flowering total cost of a whole grow done under a 250 including veg time and fans, pumps etc wud b around £20 or 20$ if yur electric was 7cents. i think its around the 3cent mark in NY just half all my costs. disclamer:: all above sums r based on a 250w
