Cyco Platinum Series Uptake is an additive used throughout the vegetative and flowering periods of plant growth to provide natural chelation and uptake of minerals. Cyco Uptake is the source of humates in the Cyco Platinum Series line of plant fertilizers. Humic acid is a stage of plant decomposition before the material turns to oil. As such, the humates exist in a state of flux as large long-chain carbon molecules. With open bonding sites, these humates are receptive to latent metals and minerals. When the humate comes in contact with a compatible material, the humate bonds with it creating a natural chelate which is a highly available form of mineral the plant may use more efficiently.
