RE: Final Stretch - Cannabis Update

All I did was rub my fingers from flower to flower to ensure male flowers pollinated female flowers.

I wonder if that would work for a peach tree!?

I can't believe how technical all of this is. I'm not much of an horticulturalist - I've got a few natives in my front yard and a lemon tree (that I managed to kill), and a peach tree in the back yard. I chose the natives, because I figured they would be the most difficult for my very non-green thumb to destroy, but your set up is way more complex than the water I pile on my plants.
I tip my hat to you for having the patience to understand how to actually care for plants and nurture them to maturity. As my peach tree starts producing fruit (got one last year - mainly because I was too lazy to cover it to protect it from birds) I'm beginning to understand the pride that comes from cultivating something yourself.

Excuse my naivety, but do your plants grow year round, or do you have to make do with one harvest a year and replant every season? Is that why there are so many varieties - so you can have yield 365 days a year, or are they just for different flavour, etc?
