Yup- I grow a couple plants at a time indoors, and I don't want to spend weeks/months (depending on how long I let it veg and how long it takes to show whether it's male or female) wasting resources/nutrients only to find out it's a male. Occasionally, a supplement shop will toss a few free 'mystery' seeds into an order, and I'll just give them away to someone who doesn't mind taking a chance. You can get a feminized seed from a good source for ~200 baht (maybe less, though definitely more depending on the strain), or a clone for ~400 baht (maybe less these days as there are several places selling them) where you know you're going to get a female.
