wanna make some hash...advice plz

well what thought to be 4 females ...turned out to be only 2 .....i would like to make some hash from the males...they are still very early in flowering only 4 days.....but i have limited space and i have to rid them from my garden...i have a feww questions for you guys...
1. can i only use the preflowers for hash? or can you use fan leaves.
2. like i said only 4 days into flowering.so there are barely any trichomes. will this be a problem?...
just want to know what you guys opinion are?... i wish i could keep them to make sure they are males.but keeping them is not an option ..very small space....should i just toss them or possibly make some honey oil or anything???? it also crossed my mind to go plant them somewhere in the hills so i could keep an eye on them....because i am not 100% they are males..one of them actually could be female....but i am not worrying about losing it....i have 2 definate sluts already so for an experiement grow that is plenty.. thanks in advace...

If you've had them in there this long, I don't understand why you couldn't wait a few days to a week to see if they are male or not.

And I am not sure that you can make any kind of potent edible/smokable just from pieces of a pre-flower plant. Then again, I could be completely wrong. I haven't done too much specific research on that. Anyone feel free to correct me.

my grow space has reduced...due to some complications... not room for 4 plants ...2 only
