Can Tomato and Cucumber share one grow tent?
One tent means one light, one timer and one climate. This is what Tomato and Cucumber each need, and which differences moving the pots can fix.
The short answer
- Light: at their most demanding stage, one light level suits both — 600–800 µmol/m²/s.
- Day length: both are usually grown at 16 h, so one timer suits both.
- Temperature: both are comfortable at 24–28 °C.
- Humidity: both are comfortable at 60–70 % RH.
Light, stage by stage
| Tomato | PPFD | Cucumber | PPFD | Suits both |
|---|---|---|---|---|
| Seedling | 100–250 µmol/m²/s | Seedling | 100–200 µmol/m²/s | 100–200 µmol/m²/s |
| Seedling | 100–250 µmol/m²/s | Vegetative | 300–500 µmol/m²/s | none |
| Seedling | 100–250 µmol/m²/s | Flowering/fruiting | 500–800 µmol/m²/s | none |
| Vegetative | 400–600 µmol/m²/s | Seedling | 100–200 µmol/m²/s | none |
| Vegetative | 400–600 µmol/m²/s | Vegetative | 300–500 µmol/m²/s | 400–500 µmol/m²/s |
| Vegetative | 400–600 µmol/m²/s | Flowering/fruiting | 500–800 µmol/m²/s | 500–600 µmol/m²/s |
| Flowering/fruiting | 600–950 µmol/m²/s | Seedling | 100–200 µmol/m²/s | none |
| Flowering/fruiting | 600–950 µmol/m²/s | Vegetative | 300–500 µmol/m²/s | none |
| Flowering/fruiting | 600–950 µmol/m²/s | Flowering/fruiting | 500–800 µmol/m²/s | 600–800 µmol/m²/s |
They share a light level in 4 of 9 stage combinations.
How to make it work
Keep both canopies at a similar height and set the light for 600–800 µmol/m²/s.
Where exactly, in your tent?
That depends on your tent, your fixture and how high it hangs. Add Tomato and Cucumber in the app and it shows where each pot gets its own light.
