I have been seeing a lot of questions on defoliating plant during flower, when? Why? And How much? So I thought I'd snap a couple of pictures.
Here is two different strains both put in Flowering on 11/5. The one in the back is Mr.Furleys Tahoe OG, I have grown a clone from this plant three times and know the Phenotype, it is a strong growing plant that does not "get bushy" so I will not remove much leaf. This plant will only get some plucking at the 3 to 4 weeks Mark. The plant in the front is a New Phenotype of Bruce Banner and is are subject. This picture is 7 day after the 12/12 flip on 11/12.
In the picture you can not see the soil/perlite through the canopy on the Bruce Banner and you can on the Tahoe OG, this is a big indicator that it's time, along with a lot of leaf laying on top of each other, Leaf sweating and excessive water uptake, transpiring and raising humidity.
I have removed 80% of the medium to Big sized Leaf in the middle, and have selectively taken 20% of the big leaf on the outside, pulled all the ties down to flatten out the plant. You can see the pile of leaves on the tray from the one plant.
here is were you get the middle of the plant to bulk up by open it up the air flow and light penetration, by pulling the outsides down I'm giving the center a chance to catch up in the stretch.
Here is the same plants 4 days later, i have done nothing but water/feed and wait. Can you see the medium?
see you on the 3 to 4 weeks Mark for the next plucking.
