You autopilot likely can only handle 15 amps so you will need relay boxes to increase the capacity to run heat, dehuey and AC.

The breaker determines the load. You could have 2 circuits in that room or just one. You will need to check that out by tripping the breaker and seeing which outlets go dark.

my vote is for 600 watt vertical or 2 x 400 flat.

Neem is your friend. In my experience with PM, it spreads fast and takes over in a matter of days. Sounds like your OK.

Vert is a whole different animal. Without reflectors you can definately get alot closer, your covering almost 4x the space so you certainly have to make the most out of every photon. Way more effecient if you can get it dialed in. It's using the inverse square law to your advantage, that's for...

Is this organic or does it belong in the toxic waste heap with eagle 20.

I see you're rocking a verticle setup. That is different than a flat/reflector setup. I have done experimented with it in the past (verticle) and would like to try it again. Doesn't scale up to 12k well for me so I went flat again.

Sure thing bro. that 4" tall plant is so defecient it is white. Must be the nutes. Not the environment. Buy another bottle of wisdom from advanced.

Coverage. How can your 600 cover any area if your bulb is 7" away? Most reflectors are designed to cover a 4 x 4' area. I have run fixtures that were so cool that plants could touch them without heat stress, still had the best results at 3ft away w/1k hps. 50-60watts per sq ft is optimum running...

get rid of the leaves. up circulation. greencure works but fucks up flowers. burn sulpher. I have heard that a metal halide lamp kills PM.

If your going to keep the light as close as possible and only illuminate a couple of square feet, get some t5's. You use a 600 to cover more area, not to burn the fuck out of whatever's under them! It does depend a bit on your hood. I have run water cooled lamps that were cool to the touch that...

Loopks like your Frying it with those ultra cool LEDS! RAISE THE LIGHT!

This often happens the first few days of flowering. Raise your light a bit, like to 24-30" above the tops and give it a few days. Don' t buy into the "closer to the tops the better" BS. Your 600 should be at least 24" away. Don't do anything drastic, it will pass.

C'mon, Scoob if your a contractor you should know better than to ask a master sparky to break code or give advice that does. I don't always follow code but I do respect it!

Window AC units are cheap and plentiful. I like them for that one simple reason. I like things I can buy at lowes and home depot right off the shelf.

If you can keep the extra room at a reasonable temp it will work fine. Window shakers are designed to work efficiently at 90 degrees. They will work well into the hundreds but not well. I exhaust 2 units into a large room. In the winter it is xtra heat for the room. In the summer it's a bitch...

Tap water in an turbo clone 48. I do ad DM Zone to keep it sterile. 100%! I do have to completely clean and disinfect with bleach between cycles.

Get a meter to start. Air cooled lights almost always leak. Portable in room AC also pull air out of the room. Check to see if you have even the slightest neg pressure in the room.

I have run 800-1000 at lower temps but like yoda said, they will only use what they need. If there's more than they need no worries as it isn't toxic at those levels.

Your putting a surge suppressor on an HID light?
