1 sachet of SHIVA Surface Cleaner (2 g) + 0.5 litre of water = 0.5 litre of ready solution. 1 pack = 24 sachets = 12 litres of solution. Always prepare the solution fresh – the ready solution keeps for no more than 24 hours.
Nutrient feeding calculator
Enter how many plants you planted and when. The calculator works out when the 14-week cycle ends, the feeding rhythm for each week, and how much water and how much of which SHIVA product to mix into one watering. You can add several plantings in separate rows. You get the result with the “Calculate nutrient solution” button below the table; your browser remembers what you entered.

SHIVA Master Pack210 sachets – the complete 14-week programme for 4 plants / 1 m²
The litres of solution per plant and watering are average values adjusted to the phase (seedling approx. 0.3–0.5 L, flowering approx. 2–3 L) – small pots tend towards the lower, large pots towards the upper value. The number of sachets can be a fraction: one sachet is always for 5 litres of water; for smaller amounts use the proportional part of a sachet.
