*To significantly reduce algae growth it is highly
recommend to attach the enclosed block wrap.

Best Installation Practices

1.	Visually inspect and ensure the system is clean and free of chemical and biological contamination.
2.	Place insert into a properly sized bucket or net pot and ensure it is properly seated
3.	Cycle the system (1) time to ensure media is saturated
4.	Place a rooted start or rooted clone into the 1,5" cutout on the top of the cylinder
5.	Visually identify that the root mass is located at the flood level of the system you are using.
6.	While many flood schedules work with the product, we encourage the grower to use a "high frequency / short duration schedule", Plant roots begin to die after 15 minutes of submergence consequently cycle duration should not exceed that value, Optimum range for mature plants is between 8 and 12 floods per day at 7 to 5 minutes per flood respectively.
7.	If using an aeroflo or drip system follow steps 1 through 5.

Best Growing Practices

1.	If you are using a traditional bucket system ensure your system drains each bucket completely at the end of each flood cycle. Many systems allow standing water to remain in the bottoms of their buckets consequently leading to root borne disease, damping off and occasionally death of the plant.
2.	If using an aeroponic system ensure the sprayers are providing adequate nutrient flow to the media.
3.	If using a top drip system position the dripper stake directly above the central root mass for optimum results.
4.	When using a flood table or bucket system carefully arrange the plants in a manner that will allow mature plants to receive optimum light and air circulation.
5.	Maintain constant aeration in your reservoir. Regardless of media, your nutrient solution should be continuously aerated to achieve maximum results, This is one of the most common problems associated with novice growers.
