Our Greenhouse & Polytunnel soil mix is a nutrient rich mix of compost, plant feed and soil to creaete a superbly well fed growing medium with a beautiful crumbly consistency. Our indoor growing mix contains over twice the amount of seaweed and poultry manure feed than our supersoil mix becuase indoor plants like tomatoes, peppers, cucumbers and courgettes are demanding plants with high nutrient requirements. We have also doubled the ratio of Envirogrind soil conditioner and compost to give an all round high nutrient compost.
Our greenhouse and polytunnel mix is also ideal for outdoor growing where a high nutrient growing medium is required.
Supersoil mix ingredients:
Seafeed is our own brand pelleted slow release plant feed. Seafeed is a mix of organic free range poultry manure whihcb is composted with seaweed meal to provide a natural feed that will supply nutrients for up to 90 days. The addition of the seaweed meal helps to boost plant immune systems and improves soil quality.
Envirogrind is a very high grade compost made by composting green and fish waste in large aerated bays. The finished product is extremely well broken down with very little woody material present. Envirogrind compost is the very best commercially produced compost and is used as a soil conditioner and slow release plant feed.
10% mushroom compost
Mushroom compost is the waste compost material left over from commercial mushroom farms. Mushroom compost is a compost base with added horse manure and gypsum which creates a slightly alkaline mix which helps to balance the pH our soil mix.
50% Screened Topsoil
The heart of our supersoil mix is our screened high grade topsoil, we only use the best soils with low clay content. Our soil has also been screened to remove any large or medium sized stones.
