Green Planet 70/30 Coco Perlite 53L

Green Planet’s 70/30 Coco Perlite blend is a professional‑grade growing medium combining the moisture‑retaining benefits of coconut coir with enhanced drainage via perlite. This pre‑mixed substrate is buffered, pH stabilised, and certified to RHP horticultural standards ensuring consistent quality, low salt content, and a clean medium free from pests and chemical additives. Use it straight from the bag in containers, hydroponics, propagation trays or as part of your soil mix.

With 70 % high‑quality coco coir and 30 % perlite, this blend helps maintain an optimal air‑to‑water ratio in the root zone—promoting stronger root growth, better nutrient uptake, and reduced risk of waterlogging. Its eco‑friendly and biodegradable nature further appeals to growers seeking sustainable solutions. Ideal For:

Growers needing a ready-to-use coco/perlite medium (no mixing)

Container gardening (vegetables, ornamentals, herbs)

Propagation and seedling stages

Growers aiming to reduce peat use and adopt sustainable substrates Key Features:

Balanced moisture and aeration – 70 % coir retains water while 30 % perlite improves drainage and air flow.

Pre‑buffered & pH stabilised – Ready for use, with stabilised pH (approx. 6.5) and reduced salt load (EC 0.36 mS/cm)
- Low initial EC – Minimal residual salts, reducing risk of nutrient lockout in early feeding.

RHP certified quality – Each batch meets rigorous standards for purity, structure and consistency.

Clean and inert – Free from pests, weed seeds, and chemical additives.

Sustainable & biodegradable – Made from renewable coconut husks.
Frequently Asked Questions

Is this blend ready to use out of the bag?
Yes. The substrate is pre‑buffered, pH stabilised, and cleaned so it can be used immediately—no pre‑rinsing or treatment required.

How often should I water or feed?
Watering frequency depends on crop, container size, and system. Coco/perlite substrates generally favour “many‑small" feedings (e.g. drip or multiple feed cycles). Monitor runoff EC and adjust accordingly.

What pH and EC should I aim for?
Start with a nutrient feed pH of 5.8–6.3, and aim for EC within your crop's recommended range. The substrate’s baseline is about pH 6.5 and EC ~0.36 mS/cm as packed.

Can I reuse the substrate?
Some growers rinse and rebuffer used coco mixes, though performance may degrade over multiple cycles. Ensure proper flushing and reconditioning before reuse.

Is this substrate pest‑ or pathogen‑resistant?
Yes. Because it is thoroughly washed, buffered, and certified (RHP), the blend is free from pests, weed seeds and typical soilborne pathogens.

Can I mix this with other media, like compost or perlite?
Yes many growers blend this substrate further (e.g. 20 % compost/worm castings). Just treat the resulting mix as a fresh medium and adjust your feeding regime accordingly.
