HI Roots
I to, would like to try the powder feeding, sound just right for an old fart like me who can't remember things lol
I am able to order it from GH seed for 40euro and 40 shippin about $102 dollars for 1000 grams.
Which would last me for a year and a half.
I have been researching but not a lot of deffinitive info on it, think I will give it a go anyway.
Good luck
