Can you not find it anywhere local? Farm and feed stores have it, any agriculture/landscaping place can get it.
I think I pay 30 for a 50lb bag.
maybe amazon prime if you have a friend that has it.
I buy all the salts I can’t source locally from customhydronutrients.com
If you buy from a store make sure it’s not tropicote, make sure it’s solution grade.
why not search for jacks cal nit instead.
because jack's calcinit has a higher level of sodium chloride and does not work as well as yara.
I've just begun researching Jacks and saw in the cheapest hydro nute thread Yara is recommended. Ive seen others using jacks.
Do you have the numbers?
