Seed Starting Mix with Worm Castings – 5 Gallon Bucket

Not sure where to start your garden? Start here.

No experience needed. No giant bag of soil to haul home. Just grab a bucket, grow bag, or a container, grab some seeds, and grow something! Our Seed Starting Mix with Worm Castings is everything a first-time (or casual) gardener needs to get a few veggies in the ground — or on the patio — without the overwhelm.

Each reusable 5-gallon bucket holds approximately 0.65–0.75 cubic feet of a light, airy, nutrient-rich blend — the perfect amount to fill a tray of seedling cells, a few small pots, or a grow bag. No measuring, no mixing, no guesswork.

• Blended with worm castings for gentle, bioavailable nutrition from day one
• Fine, well-draining texture promotes strong root development and prevents damping off
• pH-balanced and low in salts — safe for even the most delicate seedlings
• Ideal for peppers, tomatoes, cucumbers, melons, squash, herbs, and more
• Packaged in a reusable 5-gallon bucket — no bag waste, no mess

🪣 Using This Mix in a Grow Bag or Container

• Fill your grow bag or container and water thoroughly before planting — let it settle for 30 minutes
• This mix drains fast by design — check moisture daily in hot desert weather and water when the top inch feels dry
• Grow bags dry out faster than pots — bottom watering or a drip line keeps moisture consistent
• Place in full sun (6+ hours) for best results with tomatoes, peppers, cucumbers, and squash… or whatever your desert garden needs
• Refresh with a light top-dress of worm castings or compost mid-season to keep nutrients flowing
• At season’s end, mix can be composted or reused with amendments — the bucket cleans up and stores flat

Whether you're dabbling for the first time or just want a no-fuss way to start a few plants, this is your starting point. SJR Growers Co has you covered from seed to harvest. 🌱
