Nice, one light will work, but are you LSting? bc the light may be only reaching the top canopy!
no doesnt involve chopping lol you are just tying down branches to open it up so light can reach the other bud sights ( i believe thats what lst is)
yea you have to lst or something cfls arent good for penetration, if things work good for you try invest in a HPS light youll be way happier with the results
