What makes Allgood Farm’s soil mixes different?
We believe our mix is the best soil for Semi Hydro Mix thanks to the high-quality and sustainable ingredients we use.
In the mix: expanded clay grit, pumice crush, zeolite grit
Unlike your run-of-the mill garden centre potting soil, our specialist soil mixes are designed to recreate the natural habitat of your individual plants. That means a lot more goes into them than just compost!
We pack Allgood Farm repotting soils with varied ingredients to reproduce natural soil structure, aeration and moisture balance, with each mix tailored to a specific plant or family of plants. Our soils contain wholesome natural additions like pine bark (from sustainable British forestry), sphagnum moss (hand harvested in Wales), expanded clay (we use various grades and shapes chosen for each mix), and many others.
Our soils are also boosted with bioactive worm castings, a rich compost full of nutrients, which helps to keep your soil’s microbiome healthy.
Allgood Farm soils are natural, living products – we never bake them or add pesticides – because sterile soil is dead soil!
How to get the best results with Allgood Farm Semi Hydro Mix soil
Allgood Farm soils are living products – free from pesticides and naturally alive with a beneficial microbiome.
We recommend giving your semi-hydro mix a rinse before use. Also rinse off any soil clinging to the roots of your plant before transferring to a semi-hydro pot. It’s best to use transparent plastic or glass pots, and fill to around 1/3rd with substrate. Next, centre the plant and backfill around the roots, before adding water to 20-30% of the depth of the pot. The water (and any soluble fertiliser added) will naturally wick up into the substrate to keep roots moist but aerated.
Allgood Farm soils are rich in organic matter – that’s what makes them so nourishing for your plants! But what’s good for your plants is also nourishing for other things – namely, fungi and bugs.
The odd appearance of a random plant pot mushroom is known to be a sure sign of healthy, nutrient-rich soil. However, fungus can sometimes be a sign that your soil is being kept too moist, and this may attract the dreaded fungus gnat.
For most plants, we highly recommend watering from the bottom, ensuring the top of the soil doesn’t stay damp – this will greatly reduce any chance of infestation as well as helping to avoid root rot.
Also consider a pot-topper – a layer of grit or bark that will look nice and help keep any nasties from your soil.
How much Semi Hydro Mix soil do you need?
We like to give you a range of options when buying soil as we know not everyone has the space or budget to buy a big bag, especially if you’re only repotting one small plant.
- Our 1-Litre pouches hold just enough to fill a typical small terracotta plant pot of up to 4.5 inches (11.5cm) diameter.
- A 3-litre bag should fill a pot of up to around 6″ (15cm) diameter.
- A 5-litre bag should fill a pot of up to around 8.5″ (22cm) diameter.
- A 10-litre bag should fill a pot of up to around 12″ (30cm) diameter.
Like most products, you get more for your money when you order a larger quantity, as the overall shipping, packaging and labour costs are reduced. Please consider whether the price and volume you’ve selected is right for you before you buy.
Please note: Allgood Farm Semi Hydro Mix soil is sold by Volume (Litres) not by Weight (Kilos).
This is the standard way to sell soil because you need to know how big a pot you can fill with it, not how much it weighs. Your kitchen scales might have a ‘Litre/ml’ setting but this is calibrated for the weight of water and can’t accurately ‘weigh’ a litre of any other material.
