Roots Organic 707: A Heavier, Wetter Mix for Big Containers
Formula 707 is the Roots Organics blend for growers who want to steer feeding themselves. The base is coarse peat and coco fiber with compost, cut with less perlite and pumice than the Original mix. That change gives it greater water holding capacity, which matters most in large containers that dry unevenly. Roots adds a light charge of worm castings, bat guano, fish bone meal, soybean meal, feather meal and kelp meal. The goal is a sound starting point with plenty of room left for your own program. The bag itself is the container. It is a 30-gallon grow bag holding just under 20 gallons of mix. Poke drain holes in the bottom, cut off the top and plant. Hydrofarm lists the filled bag at about 30 x 33 x 5.5 inches lying flat and roughly 63 lbs to ship. Plan on two people or a cart. The bag sits on the floor or a tray and serves as the final container.
A Feeding Schedule That Fits 707 Soil
Because the nutrient charge is light, 707 soil is not a water-only mix for a full cycle. Retail guidance puts the first feeding about 10 to 14 days after transplant, earlier than richer hot mixes. Growers who have run it report the built-in charge fading somewhere around six weeks. Start with a mild organic or liquid feed and build strength as the plant fills the bag. The higher water retention means fewer irrigations, so let the top inch dry before watering again. Lift a corner of the bag to judge weight, since a wet 707 bag is noticeably heavy. Keep the floor under it clear of standing runoff to avoid fungus gnats. Growers who want a fully amended, water-only soil should look at a hotter blend instead. For those who prefer running their own nutrients over a stable base, this is a sensible middle ground.
