Then 200 ml once a week and that worked for us. If your plants aren’t producing they may need more nutrients. **Q: Is this post sold as 2 32 oz containers of base a and base b? or two 16 oz containers of base a and base b?** A: It is 2 bottles each contains .946 liters or 32 ozs **Q: Does this nutrient line work well in soil?** A: I have been using these along with Golden Tree, SuperThrive, Heavy Boost & an enzyme blend. I use this combination every other watering. The alternate watering I use the Fox Farm nutrients. Last crop was excellent. This crop may be even better! Will most likely continue using these 2 nutrient sustems. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Impressive nutes! *by J***X on April 10, 2026* 3 weeks old Sunday and almost 1ft tall and wide.
