Consistency is key when growing Craft Cannabis, and what makes Think Tank's fertigation system different to the others is the fact that it is purpose-built for the cannabis industry. They believe in batch preparation of nutrients rather than inline dosing due to the complex formulas that cannabis growers use. It is difficult to achieve a homogeneous mixture and pH when dosing inline, but if you prepare batches of nutrient formulas that have been pH balanced you know the plants are getting a consistent set of nutrients.
