House & Garden Nutrients FAQ's
Pick the bottle that matches the medium. Soil A&B is for potting mixes, Cocos A&B is for coco coir, and Aqua Flakes A&B is for recirculating hydroponics such as DWC and flood-and-drain. The three are not swap-ins for each other — each formula is written for how that medium holds and releases nutrients, and using the wrong base is the problem this brand most often shows.
Roots Excelurator works in the root zone during the first weeks of a cycle. It is there for root development and protection, not as a feed. By volume it is the dearest bottle in the range, and the dose is very small — a little is enough, and extra is wasted as well as unhelpful. We stock it from 100mL up to 5L.
Use Shooting Powder in late flower. Mix it per litre of water and run it through the last weeks of the cycle. Buy a single sachet if you want to try it, or a box of five for a full run. It belongs with Top Shooter and Top Booster in the flowering line; it does not take their place.
Drip Clean stops minerals building up and blocking drippers, lines and reservoirs. On a recirculating or drip-fed system a furred line is expensive to clear, and this bottle is the cheap way to stop it happening. Dose it continuously at a very low rate; it is not a periodic flush.
Yes. There are three, one for each substrate. The Soil, Coco and Aqua starter kits each put the matching base with the additives House & Garden wrote to run beside it. If you are coming to the brand for the first time, a kit is cheaper and harder to get wrong than buying the bottles one by one.
