Well, that's it, so much for the male HB. Adios amigo! I'm now starting to realize that I should have switched to flower 4-5 days, maybe even a week, before I actually did. The box has filled in and got so dense, so quickly, that it's become detrimental to the light penetration. Now that the male is gone, I've been able to spread the other 3 plants out a bit more. I'm hoping this will allow the light necessary for most, if not all, of the branches to get the light they need. I really think the mylar has been a big boost to light penetration and will always plan to use it in the future.
One challenge I'll be keeping an eye on is the root ball of the remaining plant in the left bin. It's roots had heavily interwoven with the former male's roots and it was impossible to untangle them. Actually, I couldn't even begin to get them separated, so I cut down the point I felt was the middle distance between the two. There are no doubt remaining roots from the male which are now dead and will begin to decay. I will be checking again tomorrow and removing as much remaining dead roots as I can, as well as changing out the reservoir, adding fresh nutes, and especially hydroguard to prevent root rot.
I think for my next grow, I will purchase feminized seeds and only grow one plant in each bin. This way I will be able to avoid the root entanglement problem and I'll be able to spread the branches better.
