Customer Feedback

How long does the kit last? And other FAQs.
Is Starter Kit 2 good for hydroponic or soil systems?

Starter Kit 2 works across all major growing mediums, including hydroponic systems, coco coir, organic soil, aquaponics, raised beds, and even tower gardens. It’s fully compatible and easy to integrate into your current setup.
Do I have to use all 8 bottles every time?

Not necessarily. Base A & B and Golden Tree provide the foundation. Additives like CalMag & Iron, Tree Trunk, and Sweet & Sticky let you address specific plant needs — like structure, deficiency correction, or bloom enhancement. Gardeners often customize depending on stage and system.
Can I mix everything in one jug?

Yes.All nutrients can be added to the same watering container. Golden rule: Never mix them while concentrated — add each one to the water individually to avoid nutrient lockout and get the best uptake.
