The FloraSeries Trial Pack, including FloraMicro, FloraGro, and FloraBloom, allows growers to fine-tune their feed system by putting them in charge of when and how much of each nutrient to use in each stage of growth. FloraMicro is the "building block" of the FloraSeries. It contains nitrogen, calcium, and chelated micronutrients to help support fast-growing crops during all growth stages. FloraGro is blended with nitrogen phosphorus, potassium, and magnesium for support of structural and foliar growth, while FloraBloom is packed with phosphorus, potassium, magnesium, and sulfur to help encourage flower and fruit development. You can adjust how much or when to use each nutrient to create your own personal recipe. Always start with a reservoir filled with water, then add the concentrated nutrients one by one. Add FloraMicro to fresh water first and stir well, then add FloraGro and/or FloraBloom. When you use the Flora Series, you can grow knowing primary, secondary, and micronutrients are being delivered to your plants to help feed the right nutrients, in the right ratios, to help plants flourish. Good things really do come in threes.
