Yann:

Could you elaborate on the use of Amino acid.
Only on Colchicums and which Amino acid?

A note  to anyone  waiting  for  a  delivery  of the  new  Colchicum book from the  AGS :- they had  a  problem with some  of the  stock sent to them being  damaged and had to wait  for  replacements - your  order should arrive  soon.

That  gives  you time  to start the  weight-lifting classes- it's  a   HEAVY book!!


See Gail Harland's review  of the  new  Colchicum book :

I made my first trials on Ophrys. I grow in polystyrene boxes and i wanted to get good sized bulbs and lot of seeds for my invitro stock.
I then applied from august to december a large amount (too much) of pure amino acid i purchased from a spanish laboratory. 1 drop for 10l water. When i harvest my Ophrys to stock them in the garage in June i hallucinated with the bulb's size and perfect shapes.
The year after i tried on small colchicum bulbils, the size doubled in less than 6 months and they looked very healthy compared to other bulbils not watered with the magix potion. Since i reduced the concentration to 1 drop/20l + 4-6-36NPK.
Since there i now water 1 week with amino acid, one week with NPK, with at least 36K, sometimes i'm able to purchase 0-50-30 NPK (Grotek) fertiliser.

Saturday i'll post photo of the products.

I stock my mixture in a small 5l jerrican and use a dosatron pump 1/3 ratio. The amino acid don't like light and should be applied quickly with 1 week.

Thanks so much.  This sounds  so interesting.  I look forward to the images.

There are so many Amino Acids I wonder which one you  are using.
