Finally, an Oldtimer Organic PK Booster!

Plant Magic Plus Oldtimer PK 4-8 is the solution that not only gives your plants the phosphorous and potassium that they need to increase weight and improve essential oil content, but unlike any other it is entirely made up of enhanced organic nutrients.

Plant Magic Oldtimer products encourage beneficial microbial activity in the root-zone. This increases yield and root-health. For a really flourishing microherd we highly recommend using Ecothrive Neutralise to avoid the chlorine/chloramine in tap water from inhibiting, or even killing, the friendly microbes, plus a quality beneficial inoculant such as Ecothrive Biosys when growing in soil. For an extra kick, try Ecothrive Charge too!
