Frequently Asked Questions
What’s included in the Autoflower Prema Kit?
Bonnie (6-5-4), Clyde (3-6-5), CalMag (2-0-0 + iron), and Bud Booster (0-1-3)—everything autos need from seed to harvest.
How do I use each bottle across an auto’s life?
Run Bonnie + CalMag in veg, then switch to Clyde + CalMag in bloom. Add Bud Booster mid–late bloom. Bonnie and Clyde are stage-specific—don’t use them together.
What’s the exact mixing order for best results?
Water first → (if using) Armadillo Armour → Bonnie or Clyde → CalMag → Bud Booster → (optional) Sticky Bandit → Monkey Juice last → pH last. Stir between each.
Can I pair these bases with other nutrient lines?
Keep Bonnie/Clyde as your base system; you can layer Cronk additives (Armadillo Armour, Sticky Bandit, Monkey Juice, Bud Booster) as needed.
Will this work in my setup at home?
Yes—reliable in soil, coco, and clean hydro/DWC with consistent EC and pH management.
Does the kit suit vegetable autos like tomatoes and peppers?
Yep—use Bonnie in veg for canopy and Clyde + Bud Booster during flowering to support fruit set and density.
