from what i hear gypsum can be absorbed if in direct contact with the roots, so like anything BUT RDWC/aero it should be ok.
Gypsum is used as a leaching agent, not as a nutritional agent. It is not in an uptakable form.
Really? What does it leach out? Makes sense why I wouldn't want it in my RDWC then!
wow 30 thousand views on this thread, wonder how many people have made the switch. :wondering
I hope everyone's 2012 is full of savings :)
You got a website for this sixpack formula? Interested in reading up on it.
I use the shit out of CNS-17 for coco. But buying 5 gal jugs for a little under $100 is killing me. I can make it with Calcium Nitrate, Magnesium Sulphate, MKP, Potassium Nitrate, and some micronutrient mix, probably Jack's, hopefully in the form of sulphates.
When I do not have as much on my plate I will implement this and provide figures so others can duplicate.
And Hammerhead (budboy299 showed this formula I think a while ago)
And maybe MOAB(if they are not hiding a non-NPK ingredient)
Thanks everyone for helping show the way.
