Terra Aquatica TriPart Grow | High-Performance Nutrient Formula (4-1-6)

What is Terra Aquatica TriPart Grow and what does it do?

TriPart Grow is the vegetative part of the Terra Aquatica 3-part system. With an NPK of 4-1-6, it promotes strong leaf growth, stem structure, and early root development. It’s a base nutrient designed to build healthy, vigorous plants in the vegetative stage.

Do I need to use TriPart Micro and Bloom with TriPart Grow?

Yes—for balanced results. TriPart Grow provides nitrogen and potassium, but Micro and Bloom complete the macro and micronutrient profile. The 3-part system gives you full control across veg and bloom stages.

What plants and stages is TriPart Grow best for?

TriPart Grow is ideal for vegetative growth, seedlings, clones, leafy greens, herbs, houseplants, and mother plants. It’s often reduced or phased out during bloom. It also helps build structure and thicker stems when lighting and airflow are dialed in.

Can I use TriPart Grow in hydro, coco, or soil?

Yes—TriPart Grow works well in hydroponics, coco coir, and soil. Coco requires regular runoff to prevent salt buildup. In soil, use lower doses and feed less frequently. It’s also suitable for recirculating and drip systems if mixed properly.

How should I mix TriPart Grow?

Add nutrients to water one at a time—start with Micro, then Grow, then Bloom—mixing thoroughly between each. Never pre-mix concentrates together. Shake bottles before use. If using silica, add that first to plain water, then continue as above.

Do I need to adjust pH and monitor EC with TriPart Grow?

Yes. For hydro and coco, aim for a pH between 5.8–6.2. Use an EC/PPM meter to avoid overfeeding and track salt buildup. Incorrect pH or high EC can cause nutrient lockout, which looks like deficiencies.

How do I avoid salt buildup when using TriPart Grow in coco?

Feed consistently with runoff, don’t let coco dry out completely, and check runoff EC regularly. A light flush can help reset the root zone before switching to bloom if EC is creeping too high.

What are signs of overfeeding or underfeeding with TriPart Grow?

Overfeeding shows as leaf tip burn, dark or clawing leaves, and high runoff EC. Underfeeding shows as pale growth, slow veg speed, or weak stems. Always adjust based on plant response—not just the feed chart.

Can I use TriPart Grow with Cal-Mag, microbes, or silica?

Yes. If using RO or soft water, Cal-Mag may still be needed. Add silica first, then Micro → Grow → Bloom. Beneficial microbes and root boosters are usually compatible—just avoid high EC or harsh sterilants in the root zone.

Does TriPart Grow work with hard water?

Yes. Water hardness mainly affects the Micro bottle (choose soft or hard). TriPart Grow works with any water type when paired correctly with the right Micro version.

Is TriPart Grow beginner-friendly?

Yes—if you follow the basics: use proper mixing order, start light, and monitor pH and EC. The most common mistakes are running it too strong early or chasing symptoms with more nutrients instead of checking root zone conditions.

How should I store TriPart Grow, and does it expire?

Store sealed, upright, and in a cool, dry place out of direct sunlight. Avoid freezing or overheating. It’s stable when stored properly and lasts a long time—shake before use to prevent settling.

What sizes does TriPart Grow come in?

TriPart Grow is typically available in 1L and 5L sizes. For small home grows, 1L is usually enough. If you're feeding many plants or running a reservoir, 5L is more convenient and cost-effective.
