This complete nutrient kit includes two premium fertilizers designed specifically for autoflowers: Bonnie and Clyde. With Bonnie for growth and Clyde for flowering, the Autoflower Prema Kit provides a comprehensive solution for feeding your autoflowers.

Other Tips:

  • Maintain a nutrient solution pH range between 5.8-6.2
  • The optimal temperature range of the nutrient solution is 20°C - 24°C (68°F - 75°F)
  • If using a drain to waste system, allow 10-20% runoff to decrease potential for salt buildup. If no runoff is planned, reduce the PPM/EC to prevent potential salt buildup.
  • If using a recirculating system, maintain water level in the reservoir by adding fresh water and nutrients as needed. Change solution every week.
  • If growing in coconut coir-based media or if using reverse osmosis water, add 1-1.5ml of Cronk Nutrient's CalMag 2-0-0 to the nutrient solution recipe.

Frosty buds

Received the autoflower nutrient pack about one week into flower, the buds are very frosty and getting nice and I went ahead and ordered the monkey juice and the sticky bandit for the next grow, can’t wait to try them all out together from the start. Definitely will be ordering more in the future 👍
