Mars Hydro FC6500 vs Growers Choice ROI-E720

[GET MO]

Whats up folks? Doing one more side by side!
Running 12 plants on each side, 2 gallon coco, slightly amended, dtw with Jacks nutrients. Strains are Outlaw Cookies, Hunter Smoke, Zev, Sour Bubble x gg4bx7, Durban Poison, and Apple Fritter.
Plants went slightly into flower so are in the process of getting back in the groove of veg, then will be flipped when ready. Lights are at half power until they kick into fast mode with the veg.

Hey, just tagging really but a little concerned about the d.e. it looks to be in powdered form, which is a real health issue if it gets in your lungs. You've got a fan in there, and soon sticky buds.

is this side x side in the same tent?
how do that work? you'll have both lights covering both sides.
true side x side you would need two tents. just sayin'.

Any soft bodied crawler will not survive a trip through DE.

What up GMT? When they start to flower I will wash anything that hasnt solidified down the drain. Last time I did it tho I didnt have to cuz it had either turnt solid or rinsed away.

The lights say they got a 5x5 imprint. Theres a foot and a half area between the tables. They may get a little extra on the edges but I doubt it would effect numbers enough to not be an accurate comparison.
They in a shed, 9 1/2 x 5 in the grow spot.
