How do you manage to grow 500g/18oz?

Who among us made half a kilo/18oz or more in a single plant?

Please share with us how you did it and what was the final yield
Inside/outside?
What kind of lamp and how many watts?
Bucket size?
What temperature?
What kind of soil(or was it hydro)?
Which nutrient?

And of course which strain?

See scrog examples here (horizontal net trellis). If you veg one plant long enough, the screen is a great visual aid and support. Keep pulling branches through the squares and/or trimming until it looks like there's a branch in each square, not much different than a hedge. Then flip to 12/12. The footprint from your lamp will more or less match the canopy of the trellis. If you account for time that's about the same as filling each square with a cutting with shorter veg time.
