- Targeted Nutrition: Precise 2-0-0 N-P-K with 3.2 % calcium, 1.2 % magnesium + EDTA iron ends hidden Ca-Mg-Fe deficiencies in tomatoes, peppers, leafy greens, coco & hydroponics.
- 100 % Water-Soluble Powder: Dissolves crystal-clear in seconds—no clogging drip emitters or sprayers; ideal for DWC, ebb-flow, drip or soil drench.
- 50-70 % Cost & Carbon Savings: Ships nutrients, not water: powder format slashes freight costs and CO₂ emissions versus liquid Cal-Mag.
- Heavy-Metal-Free & Lab-Tested: CDFA-registered, third-party tested for purity; safe for edible crops and compliant with state cannabis regs.
- Family-Owned & Made in California: Greenway Biotech has crafted premium plant nutrients since 1989—trusted by commercial growers and home gardeners alike.
- WORKS IN ALL WATER CULTURE SYSTEMS: Formulated for recirculating (DWC, RDWC, NFT, ebb and flow) and drain-to-waste systems. Adjust rate based on water hardness: full strength for RO/distilled, 50-75% for soft tap, 25% or skip for hard water. Test your starting EC to dial in the perfect amount.
- COMPLETE 4-PART SYSTEM INTEGRATION: Designed to work with Grow Green (vegetative), Micro Green (trace elements), and Blossom Green (flowering). Always add Cal-Mag first to water, dissolve fully, then add remaining nutrients in order. Prevents calcium precipitation and keeps all nutrients in solution.
- LED GROWS MAY NEED MORE CAL-MAG: High-intensity LED lighting increases transpiration rates, pulling more calcium through plants faster. Many growers report slightly higher Cal-Mag rates under LEDs compared to HPS. Monitor for tip burn and adjust accordingly - prevention is easier than correction.
- HEAVY METAL TESTED FOR FOOD-SAFE GROWING: Every batch is laboratory tested to verify freedom from heavy metal contamination. CDFA registered and manufactured in California, USA since 1989. When growing consumable crops, purity matters - trust a company with 35+ years serving serious growers.
- WHO THIS IS NOT FOR: This is a concentrated supplement requiring mixing, measuring, and EC monitoring - not a complete standalone fertilizer. If you have hard tap water (EC above 0.5), you may not need additional Cal-Mag. Not recommended for soil growing or gardeners wanting pre-mixed solutions. Test your water first.
