My builder uses Houzz Pro to plan the timeline and give detailed estimates and daily updates with photos of progress, and provide invoices at pre-agreed key points in the build. This made the whole experience much more efficient and stress-free.

nutrient manufacturing process

22 years ago

Hello

Is there a way a lab can determine the manufacturing process of an already mixed fertilizer? Can I have one tested and tell what strength Magnesium Phosphate was used and what % of the makeup it is, even when other Magnesium sulfates have been used.

Most popular brands of liquid hydroponic fertilizer dont divulge the manufacturing process as it is a trade secret. Any more help would be great.
