Tips for use
- Always check the pH – ideally 6.0–6.8 in soil and 5.5–6.5 in coco
- Increase doses gradually – especially with sensitive varieties
- Let tap water stand before use – so some of the chlorine can escape and the water reaches room temperature
- Never spray foliar feeds such as Alg·A·Mic under running lights or in direct sunlight
- Don’t overfeed – it is better to dose slightly low and adjust as needed than to risk nutrient burn
Why BioBizz is ideal for beginners
The BioBizz system is especially suitable for beginners because it is easy to understand and forgiving of small mistakes. On top of that, the organic formulation supports natural growth without harsh mineral salts.
