Bat Guano

Hi everyone

My plants are 19 days from seed and doing well - I recently fed them (foliar) Halo harpin protein and all is well. I also have some vintage bat guano and wondered when would be the best time to feed it to the plants. I dont plan on giving any nutes til it's time to flower as my soil should have enough til then and didn't know if the guano is classed as a nute and to apply the same rule?

Bat guano is a nutrient but it's composition varies. Some are very high in nitrogen, some high in phosphorous. In any case you have to be careful how you feed it to your plants as it's very 'hot' and can burn the roots.
