Hortilux Bulbs produce noticeably bigger, fuller flowers and overall heavier yields. Extended lifespan means they maintain results after multiple growth cycles, saving you money.

The Hortilux bulb produces 17% more total spectral energy and 25% more light energy in Violet, Blue and Green than a regular High Pressure lamp. This means noticeably bigger, fuller flowers and overall heavier yields, with greatly reduced etiolation and overall increased plant response and accelerated growth.
