Know before you buy
No, it is a bloom-boosting supplement rather than a complete fertilizer. It is designed to be used alongside your existing primary fertilizer program to provide an extra push of phosphorus and potassium during the flowering stage.
Yes, Soul LBS is highly soluble and suitable for both soil and soilless growing environments, including hydroponic systems. Its easy-dissolving formula helps prevent clogging in irrigation lines.
