Can Basil and Parsley share one grow tent?
One tent means one light, one timer and one climate. This is what Basil and Parsley each need, and which differences moving the pots can fix.
The short answer
- Light: at their most demanding stage, one light level suits both — 245–295 µmol/m²/s.
- Day length: both are usually grown at 16 h, so one timer suits both.
- Temperature: both are comfortable at 22–24 °C.
- Humidity: both are comfortable at 50–65 % RH.
Light, stage by stage
| Basil | PPFD | Parsley | PPFD | Suits both |
|---|---|---|---|---|
| Seedling | 100–200 µmol/m²/s | Seedling | 100–200 µmol/m²/s | 100–200 µmol/m²/s |
| Seedling | 100–200 µmol/m²/s | Mature | 175–295 µmol/m²/s | none |
| Growth | 210–310 µmol/m²/s | Seedling | 100–200 µmol/m²/s | none |
| Growth | 210–310 µmol/m²/s | Mature | 175–295 µmol/m²/s | 210–295 µmol/m²/s |
| Mature | 245–380 µmol/m²/s | Seedling | 100–200 µmol/m²/s | none |
| Mature | 245–380 µmol/m²/s | Mature | 175–295 µmol/m²/s | 245–295 µmol/m²/s |
They share a light level in 3 of 6 stage combinations.
For plants whose target is daily light (DLI), the PPFD shown is at their usual day length. On a different timer it changes.
How to make it work
Keep both canopies at a similar height and set the light for 245–295 µmol/m²/s.
Where exactly, in your tent?
That depends on your tent, your fixture and how high it hangs. Add Basil and Parsley in the app and it shows where each pot gets its own light.
