Flipping to flower - any techniques I should use?

The plant is still quite small, flipping now won't give you much yield. I would wait until she is at half the maximum height that your light can go. Being an Indica dominant plant, stretch should not be that much, maybe in the order of 50-75% max. Tying the main stem down and aiming for a level canopy, like a table, will make flowering more effective. By tying the main stem down, this will also encourage the side branches to grow, giving you multiple colas. Hope this helps,............ Organoman.
