In the early 90s I grow hydro before most people even knew how to do it or even heard about it. I used to get a qt of grow and a qt of bloom, does anyone remember what it was back in the day. I know after storing it for a while it would crystallize at the bottom of the qt. Never had to use calmag back then.
you sure it wasnt jacks? only thing i remember is jacks and that miracle grow crap ,i only grow in soil though i tried back in 2019 to do a trash can grow of watermelons , did ok with it in the heat outside, was a check water 3 times a day nightmare for me, the ph would drift from 5.8 in the morning to 7 in the afternoon, bicarbonate is how i half way controled . the water is too much work , im lazy hahaha i did get 2 melons though , then i had heart surgery right in middle of growing them and the can thing went to the can , mama kept my inside grow going and did a fine job at it for someone that just watched me do it day in and out , i got 18 or 19 zips off it and just now last night smoked the last of it , i would still have 6 if i wouldnt have helped out what i thought was a friend , she took it and traded it for some dang crack . lesson learned i did try to help someone in need out
No this was in 1992 growing in Rockwool on a table being flooded twice a day. For a promix grow I use 3 parts Master blend.
I was thinking it was advanced nutrients but didn't know if they were around back then. It was just something I was thinking about remembering the passed. Thanks for the replys.
