BioGuano FAQ's
Seabird guano is accumulated seabird droppings. Growers have used it as fertiliser for centuries because it is naturally high in phosphorus and nitrogen in plant-available forms, plus trace elements. As an organic input it feeds the soil biology as well as the plant, so it belongs in living soil or a biologically active medium rather than a sterile hydroponic system.
They work best where biology can break them down — living soil, coco with a microbial programme, or an organic potting mix. A sterile recirculating system is a poor fit: organics can foul the lines and are harder to dose accurately. If you already run hydro, check that the system can support biology before you move onto an organic range.
Both are 2kg dry flowering feeds. Micro Sea Bloom is marine-derived, so the trace element profile is different. They do the same stage rather than stacking, so most growers pick one. Because they stay dry they ship cheaply and keep well if sealed — weigh the dose instead of scooping, and dissolve it fully before you feed.
Yes. Organic Lawns and Organic Gardens are written for general garden and lawn use, not an indoor tent, and each bottle is 2L. Few hydroponic-adjacent brands make a lawn product at all. The point is consistency: if the grow room is already on organic inputs, these let you feed the rest of the garden on the same footing.
Less tightly than mineral salts — and that is expected, not a fault. Organic inputs wait on biological breakdown, so not everything you add is in solution yet and an EC reading understates what is really there. Watch the plant over several days instead of chasing a number that afternoon, and stay on the label rate rather than freelancing.
