Good to know, I collect and use rain water so I donโt get those kinds of numbers but interesting!
And if you donโt mind me asking, at what phase or how often would you add the silicate supplement?

Iโve been wanting to try other runs with other nutrients as a comparison of what Iโm doing now.
I started with fox farm trio, it went well but kinda costly at bigger scales, then I mixed fox farm with natural home made compost tea, (which is a fancy way of me saying , my wife and I put scraps in a bucket, we add water , wait a week, then add that to the plants) lol
This has been going great tbh, recently we only do compost tea, but Iโm on the fence of like seeing what other nutrients can do to have multiple grow experiences using different solutions
