Tbh if you havent started to flower it will be pretty hard to tell if they are male or otherwise. I've had some plants in the past that have stretched to high heaven, been sure they are male, then when it's come to flower-time i've been pleasantly surprised.
As for hash making on low yeilds, with male plants I personally wouldnt bother... but it might be good to just have a practise and get some experience.
Here is the Hash pass that i use for my trim... or most of it
- Please note I am writing how I make hash from trim, it might need a little adjustment for leaf material and the yeilds will not be as big or potent. You may also need to adjust screen size accordingly. The basics, however, are exactly the same.
What you need: Plenty of chilled, Icy water + ice cubes if poss, A blender or blitzer, some large jugs and a funnel (not bottles- unless u cut off the tops- so you can siphon off water) and lastly and most importantly- A screen.
Now alot of people use expensive silk screens or bubble-bags but on a budget you can use a thin, fine nylon screen. Now I get mine from the bottom of a collapsable laundry bin I had- It works great.
The important thing is that the gauze of the screen should be sufficiently fine to trap bits of leaf and plant but just big enough to allow trichomes through. After a while you will have an eye for things with the right size gauze... i have even used a stiff dishcloth in the past with decent results.
Firstly make sure the mix is DRY as bone-super dry. This will enable you to really powder the mix which will separate all it's contents. Really make sure it's ground to a decent powder, then put it in the freezer for at least an hour or two. While you're doing this get some water really chilled in the freezer or fridge and sort out some ice-cubes.
Next take the chilly mix and put into your jug, you want at least 2/3 of the jug for water so make sure it is big enough. The freezing will have stiffened any trichomes in the material and help them break away from the leaf matter. Grind it about in the bottom of the jug some more now it is icy cold.
Now go grab your icy water and fill the jug. Fill it about 3 or 4 times more volume than the mix in the jug for now. Add a few ice cubes, then blitz. You want to give it a decent blitzing then fridge the mixture for 30 mins or so. Take out and blitz again, adding a few Ice cubes and a little more water. The more water you add the easier it is to separate but the longer it will take to siphon off later- bear this in mind.
Now for the important bit. Take your freshly blitzed mixture and slooowly pour it through your screen in the funnel into another equal sized jug. The crap collecting in the gauze is unimportant (except for a 2nd wash) so concentrate on the filtered mixture dripping through. It should have no bits of plant matter but should be a little opaque and hopefully a light brown/orange/green colour. This is what will settle to make your hash.
Once you have drained the whole batch give the screen a little squeezing, being careful not to squeeze any visible bits into the water. You can save the wet mixture for another run if you are using trim from Bud or Buds. Take your water-mixture and put it in the fridge for an hour or so.
Now for the boring bit. Gently lift the jug onto a surface and if you look carefully you will hopefully see a grey/browny/green layer at the bottom. Be careful not to disturb it.
Everyones method of siphoning off the top water is different. Ive used everything from spoons and large syringes to sipping the water from the top! You may even need to gently spoon off the liquid when you get close to the hash at the bottom.
Once you have got rid of most of the liquid, spoon out the hash onto a credit card and press with another card to quickly get rid of moisture. Then leave it to dry.
You should come back to some lovely goldeny brown hash- if you got the screen size right that is!
I hope this has helped man... bear in mind this is a basic technique and will not yeild as much as some hash passes. You can get as technical as you want making hash (solvent pulls etc)... but I like to keep it simple and have never had a failed pass yet.
Good luck... and keep growing!
