Guava hashplant breeding update
I have just flipped my tent full of guavas to flower on october first, which puts me on track to harvest from late november to early december. These have sometimes flowered in barely over a month, so it may be sooner.
I had intended to flower these about 3 weeks ago, but the wildfire smoke really interfered with my ability to work on my grow.
I definitley “overgrew” my tents. There are also 2 giant “guava F” cuts in my other tent. I will have to squeeze at least one of them in with the rest of these so it can be pollinated.

These are not stretching, so much as exploding. Look at my vertical lighting for size reference, those fixtures have 2 foot fluorescent bulbs. You may notice some mangled and bent leaves on the F2 guava at the far right, that is because it has just been manhandled and staked to keep it out of the bulbs.
This is the last F1, and as you can see it’s extremely male. This is a best case scenario, because now I can spread these good bodhi f1 genetics around as much as possible. Every other plant in there is a guava f2. Finding an f1 male means I can perform an f1 incross with my f2’s for maximum genetic diversity within my selections. I can also use this to hit my guava F cuts for a completely new f2 selection.
Hopefully I can make room in the tents by culling a few f2 males. I will want to make sure this f1 male produces good pollen before I make any selections. The most important trait I look for in male plants is copious production of healthy viable pollen.
Fortunately, the f1 male preflowered within 2 days of switching to 12/12 photoperiod. This is good because photoperiod sensitivity is another trait I look for (it indicates early flowering when the line is grown outdoors), and also because the f2’s have not sexed yet. This will give me time to evaluate this male while the other plants are still determining their sexes in the preflowering stage.
