LoL.
Yes, you can buy feminised seeds, but often they are made by
incompetent farmers; which produce female f1 seeds.
Those seeds OFTEN present hermaphrodite nastyness.
I know good ones, they just cost like 200 - 250 dollar for 11 seeds.
Buy NORMAL seeds for like 30 bucks, find a nice female and clone her.
You'll have EXACTLY the same plants.
OR:
Find a nice female and male create your own seeds?
It's soooooo easy to make those f1 seeds
You will have thousands naturally occuring seeds...
No manipulated bullshit.
With natural occuring seeds you can also tip the odds to your favor
when germinating seeds and growing them to get ready to produce fruits.
You can easily get 80% + female plants from natural occuring seeds...
Also get a high pressure sodium lightbulb.
Get a transformer that goes with it.
Probably 400 watt will be perfect for you. Maybe even 200 watt.
Cost about 100 dollars for both together.
Just a lightbulb in the room won't do though.
You need ventilation.
Controlled temperature, at least keep it below 30 above 25 celcius.
You need nutrients.
Maybe a filter against the smells.
And so on
Growing outside can produce REALLY proper weed; just shield it from rain.
Preferably you force them into the flower cycle like mid juli or something
But in the end there is no lightbulb that can compete with the sun.
Growing inside usually produces a better quality of sensemilla,
and leaves more control to the grower while eliminating most variables.
And sensemilla, means weed with NO seeds. Good luck.
