How many litres of nutrient solution does 0.25L of Alga Bloom yield?
At the maximum dosage of 4 ml per litre of water, 250 ml of Alga Bloom yields approximately 62 litres of nutrient solution. This is sufficient for a small grow with 3 to 5 plants throughout a complete flowering period. Starting at a lower dose will naturally extend your supply further.
What is the difference between the 0.1L and 0.25L Alga Bloom bottles?
The formulation is identical — both contain exactly the same organic formula with NPK 3.3-2.3-5.4. The only difference is volume: 100 ml (25 litres of solution) versus 250 ml (approximately 62 litres). The 0.25L bottle offers more content for a better per-litre price and is suitable for slightly larger grow projects.
Can I use Alga Bloom 0.25L on coco coir substrate?
Yes, Alga Bloom performs excellently on coco coir substrate. The organic nutrients are effectively retained by the coco fibre and gradually released to the root zone. Bear in mind that coco coir is inherently low in nutrients, so maintaining a consistent feeding schedule with Alga Bloom at every watering is essential.
Is the 0.25L bottle suitable as a gift for a beginner grower?
Absolutely, the 0.25L bottle makes an excellent gift idea. It is large enough for serious use yet compact enough to be approachable for a newcomer. Consider pairing it with a bottle of Alga Grow 0.25L and a bag of Light Mix for a complete organic starter kit that any beginning grower would appreciate.
