How many plants do I need for perpetual harvest?

Depends on your flowering time and harvest frequency. With 8-week strains and two tents, 4-8 plants in rotation keeps you harvesting every 2-4 weeks. Try our perpetual harvest calculator to find your ideal number.

Can I plan a two tent setup with veg and flower?

Yes — this is exactly what Plantegia is built for. Map both tents, schedule when plants move from veg to flower, and see your whole rotation on a timeline. Check our tent spacing calculator to plan capacity.

How do I calculate when to start new seeds?

Count backwards from when you need a slot in your flower tent. The timeline view shows you gaps in your schedule so you know when to germinate.

Does it work with autoflowers?

Yes. Autoflowers have fixed lifecycles, which makes planning easier. Set your strain timing and Plantegia tracks the whole cycle from seed to harvest.

What about 8-week vs 10-week flowering strains?

Different flowering times change your whole rotation rhythm. Plantegia lets you set custom stage durations per plant so mixed gardens stay organized.

Is this a grow diary app?

No. Grow diaries track what happened. Plantegia plans what will happen. It is a visual scheduler for growers who think ahead.

Built for

Multi-tent growers

Running veg and flower separately. Need to track what moves where and when.

Perpetual harvesters

Staggering plants for continuous cycles. Want to see gaps before they happen.

Rotation planners

Growing multiple strains with different timings. Need the big picture.

Built as a planner first — but the Notes tool lets you track what happened too.

Works with any annual crop

Plan rotation for anything with a lifecycle.

Cannabis Photoperiod or auto. Veg to flower transitions.

Microgreens Fast cycles. Staggered trays. Weekly harvests.

Vegetables Tomatoes, peppers, herbs. Indoor or greenhouse.

Mushrooms Fruiting blocks. Rotation between chambers.

If it grows in stages and moves between spaces, Plantegia can track it.

Why not...

Spreadsheets

Dates break. Formulas get messy. No visual timeline. You spend more time maintaining the sheet than planning.

Grow diaries

Track what happened, not what will happen. Great for logging, useless for planning rotation ahead.

Calendar apps

Plants aren't events. You need to see overlap, movement between spaces, and stage transitions. Calendars can't do that.

Plantegia is purpose-built for one thing: visual rotation planning across time and space.

From growers

"Finally stopped using spreadsheets. I can see exactly when to flip each plant and never have an empty tent."

Mike 2 tents, photoperiod

"The timeline view changed how I think about rotation. Now I plan 3 months ahead instead of guessing."

Sarah 3 tents, perpetual

"Simple and does one thing well. Drag, drop, done. No bloat."
