“We need to prepare a nutrient solution container,its ok to use a 10-25 liter ordinary bucket.
The bucket lid needs DIY little ,drill a hole the size of a planter basket.
Prepare tomato nutrient solution.
Put in the air pump to dissolve the oxygen.
Place the seedlings in the planting basket and soak the roots in the nutrient solution.
When placed under a plant light, tomatoes can grow up healthily
During this time, we need to pay attention to the light.
At vegetative growth period, use more blue light, PPFD is 300-600µmol/m²/s.
At the flowering and scion stage, the PPFD can be increased to 500-1000µmol/m²/s.
We also need to pay attention to nutrient solution concentration and dissolved oxygen.
2 months later.
We can start harvesting,the tomatoes grown by ourseves is really sweet.
