How to use
Fill your pots and water the substrate. Because of the pre-fertilisation it is too strong for very young plants: wait 1–2 weeks or flush the substrate first (e.g. a 10 L pot with 5–10 L of water). Organic nutrients take about two weeks to become available, so start feeding with Alga Grow and Alga Bloom from around week 4. Extra nutrition is usually needed after about 6 weeks.
