What is drain to waste system?

Simply put, drain-to-waste is where you water your plants to a point where a recommended 15-20% by volume starts running-off, escaping the growing medium. This runoff water is discarded entirely. In a recirculating environment, the runoff is collected and used to feed other plants.Click to see full answer. Beside this, how many times a day should I flood and drain?The trick is not to over water. During the first 1 – 2 weeks, flood no more than once a day, ideally in the middle of your light period.

The frequency of watering depends on the evaporation and the water supply in the COCO. A common rule is; one daily watering is sufficient during the first few weeks under normal circumstances; then increase up to 2 times a day; 2 hours after the lamps have been turned on and 2 hours before they are switched off again.How long can hydroponic plants go without water?Some house plants, such as cacti and succulents, can literally go for months without water and should be perfect for even frequent travelers. By using watering systems such as wicks, capillary matting, and hydroculture, you can keep most plants happy for two weeks or even more.
