Strain
So about me and Jack 47.
I love that strain for his strong genetic, luxury taste, smell, sugar that he produse and efect he does.
1 problem about Jack 47 - He is sativa dominant, but some feno flying over and last year outdoor I had 1 Jack sativa dominant and 1 Jack with Indica parametrs. This Jack goes on sativa way - small buds, long flowering and after all energy efect.
About grow, at start I mean Ill kill him, but he get chance to live and goes. Jack show me he like my cruel and grow into sweet smelling imposant plant.
From me, tips for Jack 47:
1/ Grow in 10-30l pot ( 2l is too small )
2/ Grow him in veg. longer for bigger plant. He must build resistance and roots, but he rooting fast.
3/ Jack 47 is excelent strain for making clons - I prefare MONSTERCROPING
4/ Use micorhitic fungi
5/ If you like to have THC monster ( that I dont like, Im using marijuana for medicine ), use 125W light and stronger.
6/ Outdoor - Be carefull about pH - it will slow your plant sooooo much.
7/ If you like to have copule of sweet sugar, use Green House Feeding - Long Flowering
