H.P.O. Seabird Guano High N/Cal 1kg

$27.00 inc. GST

This is a truly “bee’s knees” amendment here, Seabird Guano from a mid-depth harvest! It is imbibed with a unique 7-3-2 NPK ratio along with 6.5% Calcium, and a whole host of sea derived natural trace minerals + Chitin from the specific diet the birds which produce it consume.



In contrast to the High Phosphorous and Silica guano that we also supply, the High N/Cal Guano hasn’t been as fully fossilised, yet has undergone many years of conversion, leaving unique, natural Nitrate compounds and other readily available nutrients intact.

It can be considered one of the most powerful, single amendments that you can use, and has a relatively broad application range, suiting use, particularly from the early Vegetative stages, through to early Bloom.

It is an amendment you can definitely go too far with though, so stick to low application ranges and use it sparingly.

Application rates can range from as low as 1/2 to 1 Teaspoon (1/2gram to 2.5grams) per 5L of soil.
