Low tech plants are aquatic plants that require minimal care, low lighting, and no additional carbon dioxide (CO₂) supplementation to grow successfully. These plants are perfect for:
-
Beginner aquascapers
-
Low-maintenance aquariums
-
Budget-friendly setups
-
Community tanks with slow-growing species
These plants thrive in natural aquarium conditions without the need for high-end equipment, making them ideal for new hobbyists or those who want a more hands-off approach to planted tanks.

-
Growth Rate: Slow to moderate
-
Fertilizers: Optional; thrive with root tabs or occasional liquid dosing
-
Ease of Maintenance: Very easy
-
Water Parameters: Tolerant to a wide range

Frequently Asked Questions (FAQs)
1. Can I grow low tech plants in gravel?
Yes! Many low tech plants like Anubias and Java Fern can grow attached to rocks or wood. Others like Cryptocoryne can be grown in gravel with root tabs.
2. How long should I run the lights?
About 6–8 hours per day is optimal. Too much light can lead to algae, especially without CO₂ supplementation.
3. Can I mix low tech and high tech plants?
It’s not ideal. High tech plants will struggle without CO₂ and intense light. Stick to compatible plant types within the same tech level.
4. Do low tech tanks get algae?
Algae is always a possibility, but low tech tanks typically have fewer issues due to slower plant growth and balanced nutrients.
5. Are low tech plants good for betta fish or shrimp tanks?
Absolutely! Many low tech plants provide excellent hiding spots and create a natural environment for bettas, shrimp, and other nano tank species.
6. What temperature do low tech plants prefer?
Most thrive in standard tropical aquarium ranges—72°F to 78°F (22–26°C).
7. Can I set up a low tech tank without any fish?
Yes, but you’ll need to dose fertilizers manually, as fish waste is a natural nutrient source in planted tanks.
🧾 Final Thoughts
Low tech plants are the foundation of many successful and visually stunning aquariums. They provide the perfect entry point into the aquascaping world without overwhelming you with maintenance or costs. Whether you’re setting up your first tank or just want a low-maintenance planted setup, these plants offer beauty and balance with minimal fuss.
