New Grow Room - Start to Finish

[Weird Jimmy]

A couple of questions if you don't mind....

1. What about exhaust?

2. Why use individual mechanical timers instead of just timing the whole power run?

An exhaust fan and carbon filter will be installed in the center joists of the ceiling this Tuesday (didn't have one stocked in the store, so I'm just waiting for the next order to arrive).

I already owned the timers so it's more of a cost saver than anything. If I hadn't had the timers I would have definitely put one off the sub panel for that wire.

Wow that is a very nice growroom you've constructed. Great work

great job !!!

Good clean work, very well done!

thanks for all the kind words... I'm either adding or moving a 110 outlet to the ceiling so I can put in a day/night thermostat control for my intake fan. I'll post more pics along the way.

Really nice.
How do your gavita 1000DE works? Looks a good fixture

Love this shit, nice work. Il be chillin n watching.

I love the Gavitas. As long as you can cool the room instead of the fixture, cuz they do produce some heat. And actually, Sun System is developing some air cooled reflectors to accept the double ended bulbs.

A little advice seeing you do your own electrical work. (Which looks good) you should always wrap the wire clockwise around the screw on outlets and switches. Grow looks amazing. Nicely done

awesome man, thank you for that tip. I'm more or less a complete novice at wiring, and sort of learn on the fly.

the price of those gavitas are off the top ,do you thinkk they are better than any mag or digi out there?
ive been looking at those as well as the 4000 watt ballast with built in high temp shut down and timer for 1200 bucks i cant think of the name but i'm leaning that way at the moment
plus the hoods on the gavitas dont look like there built to last or give a nice foot print

In my (and many others) opinion, large hoods are all marketing. The larger the reflector, the more space the light has to travel before it reaches the reflective material, and the more space it has to travel before it makes it back down to the tops of your plants; that's all wasted light energy. Your light "footprint" is determined by the geometrical angles inside the reflector, not it's overall size. You want the light to reach the reflective material and be reflected back down as quickly and efficiantly as possible. So essentially when it comes to reflectors, larger is not better.

As far as being "built to last", they're absolutely not built to last; they're built to be easily and cheaply replaced. Commercial greenhouses can have hundreds of these reflectors, and they calculate a 5% to 10% reflective loss from oxidation from the heat and light of a high intensity lamp every year of operation (not everyone agrees with that statement either by the way); it's much more cost effective to replace hundreds of reflectors that cost $40 as opposed to reflectors that cost $200. That's why the gavita reflector is designed the way it is.

If you want to see a good demonstration of a smaller reflector dominating a Magnum XXL, check out the OG Hood videos on growlite.com. That reflector is fucking sweet, and one of the videos really shows the light pattern that happens in a reflector like the XXL.
