BioBizz Feed Chart
This is the BioBizz schedule for unfertilised substrate and coco — roughly twice the base of the All-Mix sheet, because the medium is not feeding the plant for you. The chart below is BioBizz’s own schedule, with the doses week by week. Underneath it, our free calculator fits it to your pot size, plant count and cycle length, and works out exactly how much you need to buy.

The BioBizz Light-Mix / Coco-Mix feed chart
Millilitres per litre of water. Veg here is four weeks and flower nine, which is the commonest UK cycle. If yours is longer or shorter, the calculator fits the same schedule to it rather than simply running out.

Target pH 6.2 to 6.5. The printed schedule ends with two weeks of plain water before harvest.
BioBizz would not want you chasing an EC
This is the one place where the advice that runs through the rest of this site does not apply. An organic feed’s conductivity says very little about what the plant can actually take up, because much of what you have added has to be worked on by soil life before it is available at all. A rising EC in an organic pot is not the same signal as a rising EC in a mineral one.
BioBizz’s own advice is to be modest: a plant will not die from too little nutrient, but it will not survive an overdose. Feed the schedule, watch the plant, and resist the urge to push.
Why there is no target EC on this chart
BioBizz publish no EC for this schedule and would not want one. See above — with an organic feed the meter is measuring something other than what is available to the plant.
What a full BioBizz Light-Mix run costs
For a common UK setup, nine plants in 3 gallon Quick Fill coco bags, four weeks of veg and nine of flower, the whole cycle comes to about £552 across 7 products, mixing roughly 1,500 litres of feed.
The single biggest line on that bill is Biobizz Bio-Heaven at around £238. That is worth knowing before you order, because it is usually the additives rather than the base that decide what a run costs.
The calculator prices your actual grow rather than this example, and prices the other fifteen brands alongside it, so you can see what you are paying for.

Which BioBizz line should I be on?
Light-Mix is for unfertilised substrate and for coco. All-Mix is the pre-fertilised soil schedule and runs roughly half the base, because the medium is already carrying a charge.
- BioBizz All-Mix — For pre-fertilised soil — the base runs light because the substrate is already fed.
The calculator only ever lists the lines that suit the medium you pick, so you cannot accidentally run a soil chart in coco.
