General Hydroponics RapidStart Rooting Supplement - 500 ml

Faster Root Initiation for Young Plants - 500 ml Bottle

Slow rooting holds back everything that comes after it. RapidStart is a rooting supplement for seedlings, cuttings and young transplants, formulated to support fast, dense root initiation and a healthy root structure. Stronger early roots help plants establish quickly so vegetative growth can take off.

The 500 ml bottle suits hobbyists trying a rooting additive and small to mid-sized indoor growers who start a few batches of cuttings or seedlings. Larger operations can use it to cover regular propagation runs.

Key Features & Benefits

• Supports root initiation — helps young plants form dense roots early.
• Healthy root architecture — builds a base for vigorous vegetative growth.
• Helps recovery after transplanting — young plants re-establish more readily.
• Targeted additive — works alongside your base nutrients rather than replacing them.

Who Should Use RapidStart

Growers who start plants from seed or cuttings, and anyone moving young plants into new containers or hydroponic systems, will find it useful during propagation and early vegetative growth.

Frequently Asked Questions

Q: When should I use RapidStart?
A: Use it from propagation through early vegetative growth. That covers seedlings, cuttings and young transplants.

Q: How do I add it to my reservoir?
A: Add it to your diluted nutrient solution according to the label. Check pH and EC before feeding.

Q: Does it replace my base nutrients?
A: No. It is a targeted additive used alongside your base nutrients, not a complete feed.

Q: What does EC mean?
A: EC is electrical conductivity, a measure of the total dissolved nutrient salts in your solution. Checking it helps you confirm the solution strength before you feed.

Q: How is a rooting supplement different from a base nutrient?
A: A rooting supplement targets early root development, while a base nutrient supplies the main nutrition for ongoing growth. Growers typically use the two together during propagation.
