Hehe, been thinking the same many times.
Got warned a bit for starting with White Widow as they were supposed to be grumpy but they are fucking imortal.
Kept them on 2300ppm for 2 weeks, broke them, had light leaks, poison tent, bad pH for a period and what have you.
Feminized damn plants and still they just came back for more without a nut ever forming between them. Averaged 2 ounces/plant cured and ready, not one seed.
The genetics is rock solid. The last living thing to die on this planet will be someones Dutch Passion Feminized White Widow.
