RapidStart® Professional is a proprietary blend of nutritive plant extracts and minerals that promote explosive root growth. Using RapidStart Professional encourages the formation of fine root hairs and lateral root branching, which in term will enhance plant vigor and yield.

• RapidStart is highly concentrated and is best used during the vegetative through early flower phases when active root growth occurs.
• We recommend pre-soaking stone wool cubes, plugs and flats with RapidStart Professional nutrient solution prior to seeding or propagating from cuttings for faster root growth and success.
• RapidStart Professional is compatible with soil, soilless medias, coir, hydroponics and is suitable for fertilizer injection systems.
