Bursto's 12V led grow

So by my math I am getting a load on number of 31 watts to the light, may not be reading the charge controller correctly though lol.

So keep the area under one square foot and you might pull an ounce. With the wattage spread out like that, not so much.

i fail Math at high school,

sorry bra

but i good at fixing shit

so basically um i scabbed arround into about 5 old computers useing different fans, sum used a few amps and were great, but plus the light was 4 or five amps

so the holy grail was to find a sub 1 amp computer fan, that still was big enough

in the end i found one tha said .062amp
im like cool big blades and low amps plus the sort of...erm 2.5/3 amp pull from the Led Strip, from Shenzhen China

the whole cabinate, with the intake fan and the baby humidifier balance out at 2.7 amp 12V direct current

obviously theres no sun at night time,,,so im gonna need a 3/4 amp batterry charger at night time

so yea i think about about 30 whatts per hour

With those old PC power supplies I bet you have the parts you would need to cobble up circuits for a charge controller and voltage regulation / driver for the LED.

A 12v DC boat system I saw: 2 12v deepcycles hooked to engine electrical system (alt). customer took a voltage inverter 12v to110 AC hooked from his batteries, then plugged in a battery charger (110v) and wired it to the batteries. He added a .1A solar strip and wondered why his batteries were dying as he had a perpetual charging loop? Cool experiments, but math and electricity are close friends. 2 26 watt daylight led flouros will probably yield more= cheaper Keep it up though, rooting (lol) for ya.

nope an inline 10amp fuse straight into the load of the solar controller,

Just in case you want to go back solar.

3x18=54A, lead acid+DOD limit = 110AH for 18 +/- hours of 3A. If you use lights at night you could get away with a single 110ah battery (or 60ah lithium), if not you could always buy two smaller batteries and use one while the other charges during the day, just rotate them manually or find a controller/voltage sensing relay that will swap them automatically.

I used to start seeds under two 35w 12v hid bulbs, it was silly lol

ok so i know one battery is not enough after dark, because without a few charges at night drops to 50% or less
spose i bridge 2 x 100amp hour gel batteries to share the load overnight,
i should stay above or arround 60% of battery capacity , me thinks, by the time the morning sun hits the pannels

i have a plan now just have see if it can actually go the distance, without blowing up

buy tomorro morning i should have some better stats on battery status

me filling up the water res, only needs doing once or twice a day, lasts overnight, no problem, and also showing the humidifier wick to ya'll
