Let the flowers bloom! Designed to promote abundant floral growth, HydroTops Flora Boost, supports flowers and fruit. During the key period in the bloom cycle (weeks 4-7), plants get ever greedier for nutrients to boost the development of buds and flowers. Eventually, you reach a 'perfect storm' of nutrient uptake, and at that point you need all the help you can get to deliver the right nutrients at the right amount. HydroTops Flora Boost raises levels of potassium, magnesium, phosphorous and ammoniacal nitrogen - the key ingredients your plants need to set the optimum yield of flowers and fruit. We recommend testing of water EC levels and adjusting the dose and use of the solution accordingly, particularly from the sixth week of fruiting, in order to achieve the best flower and fruit density.
