Frequently Asked Questions
Do I need nutrients to grow plants in my tower?
Yes — plants cannot grow in water alone.
Hydroponic nutrients provide the essential minerals plants need to grow healthy and strong.
Is this compatible with the Greenly Grove™ Grow Tower?
Yes — this nutrient system is fully compatible with all Greenly Grove™ towers and most hydroponic systems.
What does each bottle do?
Each part plays a specific role:
- FloraMicro: Provides essential micronutrients and foundation support
- FloraGro: Supports leafy, vegetative growth
- FloraBloom: Supports root development and flowering
Together, they create a complete nutrient system.
Is this difficult to use?
Not at all. You simply add small amounts of each nutrient to your water and mix.
We provide simple guidance to help you get started.
Do I need to follow a feeding chart?
For best results, yes — but don’t worry, it’s simpler than it looks.
Most beginners can start with equal parts and make small adjustments as plants grow.
How often do I add nutrients?
Typically every time you refill your reservoir (about every 1–2 weeks).
How long will this last?
A quart set typically lasts several weeks to a few months for most home growers.
Do I need to adjust pH levels?
For best results, yes — but many beginners still see success without perfect pH control.
You can optimize later as you gain experience.
Can I mix all three nutrients together at once?
No — always add each nutrient to water separately and mix between additions.
