ap,
I infer by "900120" you meant 90 - 120 days. And that may be true, in some climates. But in the State of Washington? I'm not sure how good a harvest a patient could expect, in the Winter months.
New York State borders Canada. If I don't start my tomato plants from seed, early, before the nightly frosts stop, the growing season is too short to reach harvest here. And we've had hard frost here, in July.

I'm not sure how that translates to marijuana, if at all.
But I'm not sure what the problem is with one harvest per year.

However:
"I think the most sense would be made by removing these tyrannical laws" amh

"Why have any laws regarding this plant?" ap

I think you're both right.
"it is simple...control...the more things they can outlaw the more they can control us and justufy the theft of our rights and money to enforce these tyrannical laws." amh

So it might seem.
But paradoxically, outlawing this valuable crop actually relinquishes control of it to the criminals.
It provides a gigantic infusion of $cash$ into the criminal network.

- How bad is it? -

For years I've been reading that marijuana is California's number one cash crop.
I don't know if that's true or not; or how they'd know.
But if true, that suggests it's big bidness.

Why we tax payers have to subsidize the crooks, instead of lightening our tax load by taxing this huge industry is beyond me.

This Drug War is scourge to U.S. tax payers everywhere.
