4 independent rooms, 4' wide x 8' long x 8' high. Each room is equipt with 1 x 4" 165 cfm intake fan and 1 x 4" 165 cfm outtake fan.

Room 1 is outfitted with a 1000w hypotek digital ballast running a 1000w dual arc bulb. cost of this lighting system was $299.99 for the ballast, $169.99 for the reflector and $159.99 for the bulb. Total cost $629.97

Room 2 is outfitted with a Apollo 10 LED grow light that is drawing 2.65A or 325w. Cost of this setup is $799.99

Room 3 is outfitted with a Magnum Plus LED grow light that is drawing 2.42A or 294w. Cost of this setup is $1099.99

Each room will have an even number of female lowryder 2 auto flower in them. The goal is to see what if these LEDs can really stack up to a 1000w HID system and also to see which LED is producing the most GPW for the money!

update...

Ok so I am finally ready to do this first grow off, I popped 30 Lowryder2 autos and planted them on the 28th of June and moved them into 2 of my 4 x 8 x 8 test rooms. 14 are under a 1000w dual arc HID setup and 13 are under the mag+ and regular 357 magnum par amp 2012 in full veg mode. They have been on 24 hours of light since the 28th and will switch over to 18/6 for the rest of the grow starting today. The 27 survivors will be broken down to 6 per room with the extra 3 going one each into the LED rooms. The nutes being used for this grow are Advanced Nutrients...

Welcome to the forums!

Interesting comparison grow, I'm looking forward to this one. I'm a little confused though. I assume that you're only using half of that 4x8 space for the plants, right? Otherwise none of those lights is big enough to flower for that space, imho. Even the HID isn't even close and I haven't even done the w/sqft math yet. Surely, I must be missing something?

Oh, Soil or hydro?

ok so the plants have been sitting under the mag+ and regular mag and the 1000w dual arc on 24/7 light cycle since the 3rd of July. I have been watering by hand everyday and fed the ladies on the 6th, 8th and again today on the 9th.

Tomorrow the plants will be divided up evenly and placed into the test rooms. I will mark the plants that were vegged under HID and those under the Magnum LED so we can see if there is a noticeable difference in plant structure or yields.

And now here come the pics...
