How many plants, how old? It's really hard to say, you need to just go by what you think and how your plants react. But you really need drain holes and you should try lowering the temps.
hudson88 Reviewed by hudson88 on . HOW MUCH WATER WHEN WATERING? What is the perfect amount of water for plants that are in 6inch deep soil on a 3x2feet (rectangle) soil bed? I want to find out an amount that is sufficient for the plant's growth and won't rott because I don't have drainage at the bottom. Basically I want to water the plants just enough every second day without water sitting at the bottom or anything. I've heard that 300ml every second day is good (in pots), not sure how this will work on my soil bed. Any input is appreciated. Thanks! Rating: 5
