Our mission at California Substrates is to provide growers with the very best grow media for their operation. We do not add any gimmicks to our Coco Coir, such as Calcium Nitrate, to solve the challenge of high sodium & potassium levels naturally found in Coco Coir. Instead, we created a proprietary buffering process using earth friendly compounds, eliminating the need for additional CalMag or coco specific nutes. Experience The New Benchmark in Coco Coir: Unique buffering process With no CalMag needed, you can add 20-25% more NPK or similar to achieve bigger yields. Feed your plants, not your Coco. pH Perfect, Super Low EC California Substrates Coco has a super low EC. 100% Coco. No amendments necessary. We remove the fine coco dust. Growers can feed several times a day without the need for amendments such as Perlite or Hydroton. Rockwool Growers Rockwool growers can move over to California Substrates Coco without changing their feed recipe or feeding schedule. Increased Yields With no shock during transplanting and the ability to feed your plants more of what they need, growers can expect to see a clear increase in yields.
