Soil Mini

Soil Mini is Sigrow's portable, plug-and-play substrate spot-check sensor: 100% wireless with a long-lasting rechargeable battery. It measures substrate water content, EC and temperature at 2% accuracy in rockwool, coco peat, soil and perlite. Growers walk it through the greenhouse to find dry zones, hot spots and irrigation inconsistency in minutes. In a 2023 strawberry trial at Proefcentrum Hoogstraten, Soil Mini data helped cut drain water by 38% and total water use by 19.5% with zero yield loss. Growers report up to 20% water reduction and 15% better crop uniformity.
