Hey bud.
You can definitely lollipop during early bloom. Basically cut off everything that isn't receiving light, so usually every thing below the screen is cut because the thick canopy will block the light from getting below the screen.
For some people HG might be fine, but for me it was horrible. Very little pain healing properties. Low-medium potency at its best. Bland flavor.
After that grow I culled the himalayan, like most of the other folks on various forums I stay far away from greenhouse seeds' garbage genetics.
