“A” Model Flats

Our “A” Flats are at least 2.2# density (heavier than our “T” Flats) and are perfect for traditional greenhouses with raised benches that consist of a “T” rail suspension system that provides free air movement under the flats, resulting in air pruning of the transplant roots. We recommend using our Peatlite Mix for your soilless media needs, but if you choose another product – do not use sand in mix. To extend the life of our your Speedling Flats take care to avoid physical damage – and protect the trays from excessive heat and ultraviolet light when not in use.
