I just saw a video that said to drill on the low side of the tray for drainage. I've always drilled on the deeper pocket side. Have I been doing it all wrong?

So I've read that led will have to use par meter. I got those ChilLED 450W lights. Wanted to see how high above the canopy to raise the lights.

What's the ideal amount of light for veg and flower? I just got a light meter and want to know what lux or foot candle to raise the lights to on top of my canopy?

Thanks @wuzrelygud for the info. Was able to power up a double tested

Which wires goes to what just so I'm super clear on wiring these up this weekend. Thanks

120v killwatts works when running 220v power. I tried it real quick and it displayed the amps and watts.

Also the cable is too thick. Clamp meter is probably the only way.

Which cable goes where? I saw a sample with brown on 3rd spot and blue on 4th spot.

Looks like the half-550 has 4 qb304 @24"x24" frame. Think I'll just use that dimension also for my 4qb304 build.

Yes the clamp metter. I found it after I bayite which came home yesterday.

Lol sorry how do I lookup post 3576? Any anyone link it?

Planning to build a light using 4 qb304 with 2 driver to cover a 4x4 to5x5. any suggestions on the frame measurements? Got some angle aluminum from the local hardware store.

Just made the order.

My electrician wired up my 8 light controller with this plug so I can remove it easy. My goal is to get a reading for all 8 lights when fully powered.

@qballizhere Thanks for the info and reply!! I will look into how to use that bayite.

So how do I test how much amps am I pulling in my tent on 220 V power? Got a killawatt but looks like it only works with 120vac.
