Product description
Plagron Growmix with Perlite 25 L – pre-fertilised potting soil for a few pots
A 25 L bag is easy to carry up the stairs and fills just enough pots for a small tent or a balcony. Plagron Growmix with Perlite is a ready-to-use, peat-based mineral grow substrate from the 100% TERRA line, made for potting and repotting flowering plants.
How many pots it fills
One bag fills about two 11 L pots, or four to five 5 L pots for young plants. That makes it a good fit for a single small tent or for repotting a few plants.
What's inside
Peat, perlite, worm castings and fibres. A mineral pre-fertilisation of 1.8 kg/m³ (NPK 12-14-24) feeds your plants for roughly the first three weeks, worm castings support vigorous growth and water retention, and perlite keeps the mix airy and well-drained so roots can spread.
In practice
Fill your pots, water the substrate and plant. Hold off on feeding until about week 4, then start with Terra Grow and later Terra Bloom. Because you work with mineral nutrients, check pH (5.5–6.5) and EC of your feed regularly. Close the bag again if you have some left, so it does not dry out.
