I would just bend them down, and tie them to the same plant. Should be no problem at all lifting the pots then.

I've had 10' Sativas growing indoors with 5.5' ceilings! Just keep bending them and training them to keep them below the lights. Fet's 303 had colas that were 36" long running horizontally across my old room :-)

Grew dalats to term in a 4ft crawler, pinned to the ceiling in a circular pattern, they would grow down towards the floor to get the light. Never have seen anything as vigorous to date.
