about 2-3 bags full.they could be stamp sized bags or exta large lawn & leaf bags. the size of the bag will depend on about 1000 varibles including light, food,water,temps,ventalation,size of containers,how long you veg,personal skill,ect,
you cant just vent into a wall or ceiling unless the air has someplace to go. when you say into the ceiling, is there an attic above w/ vents? are you planning to pop through the wall & put a dryer vent outside? air needs to go somewhere.
only downside to making your own fixture is it is not UL approved so in the event of a fire, it WILL be blamed for the fire & your homeowners insurance will give you shit. this happened to a buddy last yr when his garage burned & insureance co f@cked w/ him till he produced reciepts to show all...
the fan in the link has a timer built in so when you turn the bath light on, the fan comes on and when you turn the light off, the fan continues to run for a minute to clear the air.the SL terminal is a trigger to turn fan on and start timer when de-energized.
that is the max you can run but for safety, try to keep loads at 80% so if you are running at 220, 3800watts or less is your goal.
your lights will draw 3800 watts but the ballasts will draw 20-100 watts each so you will be maxed out but it should be OK.I would use 2-3 different timers(timers...
you may have to add a jumper between the live and the switched live.the idea behind 2 lives is to have power to the fan all the time so that when the switched live gets power(turn the bath light on), the fan turns on, when the switched live gets turned off(turn bath light off), the fan will run...
starting them at 12/12 will not start flowering right away but as soon as the plant is ready to flower it will. the plants have to be mature enough to flower. when the leaves stop growing out in pairs and start growing on alternate sides is 1 indication it is ready. to get the most from...
what does the first amendment have to do with this? the first amendment only promises that the federal government wont interfere with your right to say or print what you want.

why not just buy a pc UPS? something like this
http://www.bestbuy.com/site/APC+-+550VA+Battery+Back-Up+System+-+Black/9307788.p?id=1218081368684&skuId=9307788&st=ups&cp=1&lp=3
most ups use a 12 volt battery so you could swap it out w/ a car battery for longer run time but if the car battery is...
assuming you are in the US,
the AC will draw about 10 amps& the light another2-3 amps so you are fully loading that circuit befor you add the fans. you will need to move the AC to another outlet on a fuse not used by much else. make sure your extension cord is rated for heavy duty use.
I hope...
the powerbars are picking up heat from the lights so that is not a problem. the best place to check is where your cord plugs into the wall. if that is hot, you got problems
not that this will help you but it might weed out some wrong answers. you are not in N.America,Right?our electric is very different than the european system.
I can't tell you what size wire you need but after powering up the circuit, feel the extension cord near the plug & keep checking it every...
you are drawing about 2 amps so no worries. if you ever upgrade, run your setup for an hour or 2 & feel the cords, if they are more than slightly warm,you may have a problem
personally, I have found that if you draw close to the max rating for extended periods, the transformer will not last for more than a few years. I have come across many Xformers that are 10-20+ yrs old & still working but they all have only 1/2 the load they are rated for.
just something to...
sorry but you wont save 1/2 on your electric bill. not even 15%. it will be slightly more efficient but not enough to notice. if I come over & pee in your pool,I made it deeper. right? thats the type of difference you are looking at.
instead of running 2 ballasts for your test, try running 1 for...
for starters, you wont be running it in the grow room so you will need an extension cord long enough to get outside.how about a powerstrip on the end o the cord?where I live we get ice storms every 5-10 yrs that can knock out power for up to a week so I bought 1 like that 10 yrs ago.it will burn...
switching to 220 will not save you any money. electricity is billed per kilowatt, not per amp.
cheapest/easiest way to start 10 seedling till they get to be a foot tall would be w/ cfls. start w/ 1-2 24 watt bulbs and add as they get taller.
