I was asking my mate about it, He was saying that it needs a 6-8 inch deep very fine seed bed liked to a onion bed, The seed needs special care kept cool even when drilling needs to be coverd up with a sheet, Possibly topped the first year(please correct if i heard wrong going deaf) Grows up to 20 feet but i think that depends on conditions loves wet ground also will grow at a rate of 1 inch per day during july aug, Grows for twenty years and i am sure he said a five years upwards will produce 40 ton not sure acres or hecters ?, As he does more i will learn more, Also a power station up north has been using up to twenty thousand ton on a weekend The big plus for farmers is it can be grown on permanent seta side ground
I found the hole thing very intresting even the small part my mate plays in the cycle
But please correct me if you know more
