Substrate Plagron Growmix

Plagron Growmix is a ready-to-use, pre-fertilized substrate based on selected types of peat with added fibers and perlite. Its light structure ensures excellent oxygen supply to the roots, while Plagron’s worm castings increase water retention and stimulate vigorous initial growth. The nutrients embedded in the mix last for approximately the first three weeks of the vegetative stage.

Advantages of Plagron Growmix

• Mineral fertilization for 3 weeks — plants receive everything they need during the start phase.
• Worm castings enhance root development and help retain moisture longer.
• Perlite improves aeration and accelerates drainage.
• Optimal base for growth and abundant flowering; maximum performance when combined with Terra Grow, Terra Bloom, and Plagron additives (Green Sensation, Sugar Royal).

Application and Parameters

Ready for planting and transplanting flowering crops. Begin fertilization after the third week, following the Terra Grow / Terra Bloom schedule and monitoring EC/pH.
