So John says seeing the soil test numbers for a green house mix will confuse me cause it does not behave like soil. I ain't having that. Gary is in town this week and we are gonna talk. But if they think I won't send it to logan they are wrong
Thats been my experience, I wont be testing my mix's until a method or lab can show accurate or relevant results.
With the sap testing, one gets a picture of whats flowing through the plants before it gets incorporated into the tissues. Combine sap and tissue testing will allow us a much fuller picture of the growing process, more info!
edit to not double post:
This is where balance is key, if your soil is balanced to the ideal for cannabis, then so should your amendment, adding only what was removed, in an ideal world anyway, easier said than done!That is gonna make re amending a crap shoot. It would also be the case with other seriously living soils or compost
