IDK, but i dont recomend fem seeds from anywhere. They are ok but too much $$$ for the odds of getting hermies. I think of fem seeds as transvestites because they are more likely to be hermies. Which share both male and female traits. And you dont want em.
But i once had a friend who grew outdoors and was limited with time to check on his plants, so what he did was take one 5 gallon bucket for every plant and drill a tiny whole in the bottom. I mean a pencil couldnt get through it. And then fill it with water, and this device leaked water on the plant while he wasnt there. I cant remember how long it takes for one to drain and how well it works but i think you can get a 5 gallon bucket and expeirament with that. Just an idea, hope it helps.
