Can Strawberry and Leafy greens (lettuce, herbs) share one grow tent?
One tent means one light, one timer and one climate. This is what Strawberry and Leafy greens (lettuce, herbs) each need, and which differences moving the pots can fix.
The short answer
- Light: at their most demanding stage, no single light level suits both. Strawberry wants 400–650 µmol/m²/s, Leafy greens (lettuce, herbs) 210–295. (Placement can fix this)
- Day length: Strawberry is usually grown at 14 h, Leafy greens (lettuce, herbs) at 16 h. One light has one timer. (Same for the whole tent)
- Temperature: both are comfortable at 18–22 °C.
- Humidity: both are comfortable at 60–70 % RH.
Light, stage by stage
| Strawberry | PPFD | Leafy greens (lettuce, herbs) | 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 | Growth | 175–260 µmol/m²/s | none |
| Seedling | 100–200 µmol/m²/s | Mature | 210–295 µmol/m²/s | none |
| Vegetative | 250–400 µmol/m²/s | Seedling | 100–200 µmol/m²/s | none |
| Vegetative | 250–400 µmol/m²/s | Growth | 175–260 µmol/m²/s | none |
| Vegetative | 250–400 µmol/m²/s | Mature | 210–295 µmol/m²/s | 250–295 µmol/m²/s |
| Flowering/fruiting | 400–650 µmol/m²/s | Seedling | 100–200 µmol/m²/s | none |
| Flowering/fruiting | 400–650 µmol/m²/s | Growth | 175–260 µmol/m²/s | none |
| Flowering/fruiting | 400–650 µmol/m²/s | Mature | 210–295 µmol/m²/s | none |
They share a light level in 2 of 9 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
Light is strongest under the centre of the fixture and weaker towards the edges. Put Strawberry under the centre and Leafy greens (lettuce, herbs) towards an edge or the back of the tent.
If Strawberry still falls short, lift its pot on a box: closer to the light means more light, without changing anything for Leafy greens (lettuce, herbs).
Day length, temperature and humidity are the same for every pot in the tent, and moving the pots does not change them. Where the two differ, any setting is a compromise for one of them.
Where exactly, in your tent?
That depends on your tent, your fixture and how high it hangs. Add Strawberry and Leafy greens (lettuce, herbs) in the app and it shows where each pot gets its own light.
