a sub panel is basically the same thing as the breaker panel with all the breakers in it for your house. trying to hook up something to a dryer outlet is like trying to splice into the meter outside without any protection. you're almost certain to have a fire. having a sub panel to plug into the...

you probably have 2 different types of ballasts. there are metal halide and high pressure sodium. they usually aren't compatible with both types of bulbs unless it specifically says it on the ballast. for a metal halide bulb you need a metal halide ballast.

trying to keep it as simple as possible, but still safe and not a fire hazard, you need a 50 amp sub panel with a dryer cord and a bunch of outlets on it for your room. you can't rig a smaller outlet to the 50 amp dryer outlet any other way without the big risk of fire. I've seen these sold...

you'll need floramicro to go along with them, that's not one you can leave out. search the forum for the lucas formula. you can grow without floragrow. I have all 3 bottles, but I've used the lucas formula for my whole first grow with good results.

ever hear of "but out". I read it just fine, and they did post pictures before, and posted better ones just a bit ago. another useless post. don't you have something better to do with your time?

I think I get what you're saying. don't plug it in how it is, you'll fry the stat. look up how to wire a thermostat, it's the same wiring as that. the ground wire is right, it goes from the plug to the outlet. the white wire is similar, it goes from the plug to the outlet and nothing else. the...

I think this may be over your head. the back and red wires do NOT go together. they are both hot wires, 240 volts. something like this, you never ever want to splice together like an extension cord, you'll end up with a fire in no time. on a lighter note, you'll have to switch out the breaker to...

I have a copy installed, just haven't put any time into checking it out yet. I just got a book, did a little reading, I think I'm liking it. they improved a bunch of things from vb6. it seems to compile a little slow on my computer. I might try using it for the next version, but I'm to far into...

I can't tell what wire goes where. you don't have any white wires connected to the humidistat, do you?

there could be a version in the future for linux and mac, maybe in a year or 2, unless someone else wants to write it.

I don't know the specs of your fans and other equipment, but the ballast shouldn't pull more then 4 amps. add on whatever else is in your grow room, and what else might be on the same circuit in other rooms. the other day I had a 400 watt ballast and an electric heater alone on a 15 amp circuit...

they sell switching boxes for big setups like this. you'd have 10 ballasts hooked into the switch, then all 20 lights hooked into that. the ballasts stay powered on 24/7, then it switches the power between the 2 sets of lights every 12 hours. actually, the numbers fooled me for a second too...

I've never tried it, but here's the info https://www.rollitup.org/view.php?pg=faq&cmd=article&id=166 I personally like cfl's better then tube florescent

I'll get you started. just do lost of reading, there is plenty of information online. the charts they give you on the bottles are for full strength nute solution. don't use full strength right off the bat, it will kill the plants. start off at 1/4 strength and work your way up from there. if the...

do we have any programmers subscribed to the thread? I need a quick beta tester. someone to just give the program and the subversion server a test to make sure everything looks good and is secure.

I have to say.. very well written

wtf have you been smoking. you don't want to mess with high voltage like that, very dangerous. it would be possible with the right equipment and a large truck battery, but the battery would be dead within an hour, if not sooner. after the first day of charging and recharging the battery after...

try hooking up the fan to the transformer without the thermostat. if it doesn't work, try reversing the wires, it might be hooked up backwards. the white stripe on the transformer wire doesn't always mean positive. factories like to non-standardize things like that.

nice thermostat. it's a millivolt thermostat, it should handle the same power ratings as an old school one, about 500ma at 24 volt max. I'm not a heating/ventilation tech, so I'm taking my best stab at this. it looks like Y and RC are for cooling, so you hook one wire from the transformer and...

how come no one else has thought of this? carbon isn't exactly cheap to replace.
