Hey friend your 48x3w grow is something to be proud of. You got 3 oz from a light only using 100 watts. That's An ounce for 33 watts which is just shy of the magical gpw. And you got it from the baby topled. That's to be applauded
I wish I could have vegged this plant long enough for that but as she is an autoflower the next best thing I can do is throw as much light at her as possible right now.
Btw the topled on for 18 hours a day costs me basically 9 dollars a month. Looking like a 3 month grow so 27 dollars plus the initial price puts me at around 120 dollars. That will buy you a half o of high quality herb around here. If I break 14 grams I break even with the topled. I'm sure I'll break 14 and maybe even double it. If each one of my branches holds a gram of bud I'm already there.
Now for the p150 on a 3 month grow I'd have to grow about an oz to break even, just due to the initial cost difference vs. The topled.
That's just comparing grams per dollar, not counting any qualitative differences that may or may not occur. Kind of like sometimes you're better off buying an oz of great stuff for 240 than some meh stuff for 180 cause you'll go through it quicker and it will cost you more in the long run.
Enough of my rambling. I need some meds.
