Can Tomato and Pothos share one grow tent?
One tent means one light, one timer and one climate. This is what Tomato and Pothos 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. Tomato wants 600–950 µmol/m²/s, Pothos 70–185. (Placement can fix this)
- Day length: Tomato is usually grown at 16 h, Pothos at 12 h. One light has one timer. (Same for the whole tent)
- Temperature: both are comfortable at 22–28 °C.
- Humidity: both are comfortable at 50–70 % RH.
Light, stage by stage
| Tomato | PPFD | Pothos | PPFD | Suits both |
|---|---|---|---|---|
| Seedling | 100–250 µmol/m²/s | Growth | 50–135 µmol/m²/s | 100–135 µmol/m²/s |
| Seedling | 100–250 µmol/m²/s | Mature | 70–185 µmol/m²/s | 100–185 µmol/m²/s |
| Vegetative | 400–600 µmol/m²/s | Growth | 50–135 µmol/m²/s | none |
| Vegetative | 400–600 µmol/m²/s | Mature | 70–185 µmol/m²/s | none |
| Flowering/fruiting | 600–950 µmol/m²/s | Growth | 50–135 µmol/m²/s | none |
| Flowering/fruiting | 600–950 µmol/m²/s | Mature | 70–185 µmol/m²/s | none |
They share a light level in 2 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
Light is strongest under the centre of the fixture and weaker towards the edges. Put Tomato under the centre and Pothos towards an edge or the back of the tent.
If Tomato still falls short, lift its pot on a box: closer to the light means more light, without changing anything for Pothos.
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 Tomato and Pothos in the app and it shows where each pot gets its own light.
