dont know what this means

PBP (living) - UC-XXL X16


What does uc xxxl x16mean

check this out only thing I see on google, will complicate you more https://www.thcfarmer.com/community/threads/uc-actual-available-nutrient-profiles.33282/

It's Microbiology.

It's telling how much of()is LIVING in the Nutrients. And we are talking about Microbes.

For example:

PBP (living) - UC-XXL X16

2.5 ml cal-mag
7.5 ml PBP Hydro Bloom
.6 ml Roots exel
Aquashield
superthrive
Protek to 5.4

CNS 17 (sterile) - UC-XXL X16

9ml CNS 17 Hydro bloom
1ml Zone
add .27
protek to 5.4

H&G (sterile) - UC-XXL X32

1.5 ml cal-mag
4 ml H&G A
4ml H&G B
1 ml zone
add .27
protek to 5.4

So basically, it's Microbe Multiplied by whatever number there is, devided By ONE individual Nutrient Value....

In short... It's worthless information..

Lol ok thaks fenian im just looking and reading I got a grow going with botanicare problend grow\bloom with lk sweets and cal mag im looking for products I can add to help my plant thrive better for my next grow

Depending on how old the plant is, go by the bottle.
Lots of people mix awhole bunch of crap together. It's up to the grower to find out what actually benefits(does anything)the plant. And what does absolutely nothing.. Good Luck
