Fungus gnats will love that environment, too.

Sorry I didn't see this sooner. HTH, Hermie

I think a 400W HPS will handle that plant, as it looks at this point.
More than 120Lb, way more!. 5 gallon buckets weigh almost 100lb when watered thoroughly. I strained my back carrying those things last Fall...lol!.
