He definitely knows his stuff in terms of growing monster plants.
Full disclosure, I’ve never used his nutrients so my observations are based on the information he provides on his website and not actual user experience.
The line is somewhat comparable to the Advanced Nutrients 3 part line. Typical 3-part base nutrient that calls for Grow during veg,bloom during flower and micro the whole way. From an npk stand point he follows the Advanced Nutrients philosophy of feeding a lower ratio of P compared to K, but Remo’s base trio of Micro/Grow/Bloom are better formulated to get you from start to finish, whereas AN’s 3 part line relies on the supplements.
If you like AN’s 3 part nutrient line but want to simplify things to 3-5 bottles, Remo’s nutrients are a step in the right direction.
Check out the videos that MedGrower1 posted on his grow using Remo’s nutrients.
