Swelling phase · Potassium K30
The final push for bigger fruit and flowers
Bazz Bloom K30 is a liquid fertiliser of superconcentrated organic potassium with amino acids, made for the last 3–4 weeks of the crop. This is when the plant gives everything to fill its fruit and flowers, and it needs potassium to move water and sugars into them: more size, more weight and more flavour.

Frequently asked questions
When do I start using Bazz Bloom K30?
Once the fruit has set and is growing, or when flowering enters its final stretch. Usually the last 3–4 weeks of the crop.
What is the dose?
0.5 to 3 ml per litre of water, once a week. Start at 0.5–1 ml/L and increase gradually. More is not better: too much potassium raises the EC and can lock out other nutrients.
Do I use it every time I water?
No: once a week, in one of your waterings, during the last 3–4 weeks. The other waterings with plain water or your other fertilisers. Finish the last days with plain water.
Is it suitable for tomatoes, peppers and fruit trees?
Yes. It works on tomatoes, peppers, strawberries, fruit trees and flowering plants, in pots or in the ground, indoors and outdoors.
Is it the same as Bazooka Bloom?
Yes: it is the same product with the same formula, now called Bazz Bloom K30.
Can I combine it with Jamaican Bloom?
Yes, during the change from flowering to swelling both can overlap for a few weeks: gradually reduce Jamaican Bloom while you bring in Bazz Bloom K30. Add each one to the water separately and mix well.
Does it change the pH of the water?
It raises it slightly. Check at the end of the mix and adjust to 6–6.5 with pH Down.
How long does a bottle last?
A long time: at 1 ml/L, 1 litre makes 1,000 litres of feed, and up to 2,000 at 0.5 ml/L. As it is used once a week, a small bottle covers many crops. Use the calculator above for your case.
Precautions: shake before use. Do not swallow. Keep out of reach of children and pets. Store tightly closed in a cool place, away from direct sunlight. Do not exceed the recommended dose.
