Total BS. I've been done this road trying to get a male and never got it. Also tried the opposite of the 'this will make a female' crap (bananas, high N, etc) Wives tales!

Violation. This is a personal use grow forum. Selling is a no-no here. (At least was when I joined)

Hey, weed is "dope" My car is "dope" my cat is "dope" and my sister IS a dope.

'Stoned man, c'mon. You should know better the people we have here. Offering up an un-housed (open frame) item for HV. There are plenty of on or off delay relays out there.

What a dryer outlet supplies is variable. you NEED to check the breaker. In all honesty, you sound too 'green' to go 3.6KW. Heavy duty mean *nothing* its arbitrary. Plywood mounting = unprofessional/homemade

For what ? They make a LOT of stuff.

Well *now* its shorted. And its no longer under warranty, since you used it incorrectly. "Gee Mr. Chevy dealer, I just drove my Corvette into a brick wall and now the windshield leaks. (along with all the fluids)"

So what the logic behind it? An outlet (typically 15A) needs a GFI within 6 feet of water. A sub panel (can be 200A) is OK within ~30 inches? Logic being an outlet is an end item and a person can be at the outlet while the sub panel is not really an end user item? Overall I'm fine with it...

hey 'Stoned. I was working in my garage, and noticed that my subpanel (built with the house not an addition) is like 3 feet from my hot water tank. This OK for code? I have an outlet near by that is a GFI.

Yup under rated. You could use a few of them if its cheaper then buying a bigger single.

How are you using them? To turn on the ballasts or to swap between bulbs? (12hrs this room and 12 hours that room) If the latter, HPS have a high voltage (over 1000volts) start up spike that can cause the contacts to weld shut. I'd suggest to use 2 contactors, one on the bulbs and another on...

I think he means the start/cap in the light, not the CAP unit.

Not gonna save you a dime. If the 208 is triple phase then there *might* be a bit of savings on motors, since they are only using 2 phases at a giving instance. I haven't seen triple phase balasts. Most industrial lighting in trip phase buildings, just use one leg of the trip phase. Power...

A dual ballast is not a switchable. Duals will run both HPS & MH at the same time. Get that full spectrum stuff going on. These are not very common, but are out there. Switchable ballast have a switch to change from a HPS to a MH. Digitals usually will run HPS or MH with no intervention...

Live in Europe?

Could use a digital timer to just turn off the ballast for one minute to spare the second relay. (just use a properly rated timer for *inductive* loads. Inductive loads are derated from resistive loads) Could get fancy and use a stepping relay and each time the ballast gets turned off it...

Just gotta watch that ignition spike HPS has. It will wear the contacts. Better off with 2 relays. One for the bulb and another for the ballast. Turn the ballast off, swap the bulbs, turn ballast back on.

No, you need a ballast also (with a cap and iginter)

What do you plan on it doing? its not going to cool a cardboard box grow room let alone a closet. Even as its intended use, it really doesn't cool items in it, but will maintain the temp And thats what 1 cubic foot max? Then you need to worry about cooling the hot side (it gets hotter then...

ohms law. its all over this thread
