Tried it..it has some thc(very little) but then it gets u a headache.Its bad bad weed,maybe its not even a weed.Thats a shame it would be very nice to have some good smoke for free..probably a hemp i dont know..
it might but its no use if the plants are hemp,in that case the sample bud probably will have under 1% thc(0.5% and so)if its hemp so theres nothing to optimize at the moment.today or tomorrow im going to take a sample and announce the results..Then your "hash" method would/might be very useful...
I think the best thing is to start again with simple growing techniques and regain your experience then you can proceed to other more advanced techniques..Thats what i would do : )
