Should I use a time release nutrient or a liquid nutrient?
Answer: Time release nutrients are applied on average once a month (ever 3 to 4 weeks). Liquid nutrients used in containers with potting soil would need to be applied around once a week. Using a liquid nutrient in containers with potting soil would provide the plants with fresh nutrients weekly, because of this the yield would be higher. Using liquid nutrients in containers with hydroponic growing medium nutrients would need to be applied with every feeding. (Every time you water).
