All-Mix comes pre-loaded with nutrients (worm castings, bat guano, perlite). Your plants kick off in top shape right after transplant, with zero fertiliser needed for the first 4 to 6 weeks.
The peat + coco fibre + perlite blend strikes the perfect balance between moisture retention and drainage. Your roots breathe and drink at the right pace — no more over- or under-watering.
Rich in mycorrhizae, trichoderma and beneficial bacteria, this substrate builds a living root ecosystem that boosts nutrient uptake and disease resistance.
80 litres in a single purchase: enough to fill 8 to 10 pots of 11L or cover a full cycle in a 120×120 grow tent under LED. Save up to 15% versus buying single bags.
Biobizz is one of the few manufacturers fully certified organic across its entire process. No chemical fertilisers, no synthetic pesticides — you harvest a pure final product with intense natural aromas.
With 80 litres of All-Mix, you can fill roughly 8 pots of 11L, 5 pots of 15L or 4 pots of 20L. It's ideal for a 120×120 cm tent under a BloomLED 300W LED lamp, or for 2 complete cycles in an 80×80 tent.
Do I need to add fertiliser with this soil?Not before 4 to 6 weeks after transplanting. All-Mix is pre-fertilised with worm castings and guano. Once flowering starts under LED, supplement with the Biobizz Bio·Bloom range or any compatible organic feed.
What pH and EC should I water with on All-Mix?All-Mix natural pH sits between 6.2 and 6.8. Water with pH 6.3 to 6.5 and EC 0.4 to 1.8 depending on stage (higher during flowering). Water that is too acidic or too hard blocks nutrient absorption.
How long can I store the soil?Stored dry, away from frost and direct heat, All-Mix bags keep their quality for 12 to 18 months. Once opened, ideally use within 3 months to preserve the microbial life.
The Biobizz All-Mix x4 pack is our best-selling format at BloomLED: 80L of premium substrate, shipped in a secure box, at the best value on the French market.
