BEST PRACTICES FOR GROWING WITH SURE TO GROW

Sure to Grow^® is a unique media that will give you superior results if you follow our simple instructions:

Which Sure to Grow product should I use?

Propagating seeds and cuttings with Sure to Grow

• Completely saturate the Sure to Grow^® media.
• Place in free-draining plant trays on a level surface to prevent nutrient run-off and migration; avoid pooling of water at the root zone.
• Deposit seeds into the pre-punched dibble holes; larger seeds and cuttings can be inserted into the cross-cut “x” in the center of the dibble hole.
• After seeding, water the seeds or cuttings gently from the top to establish good contact with the media.
• Cover with a humidity dome or another tray until the seed coat has cracked and the radicle has emerged.
• Keep the media evenly moist during germination. Top watering or flood and drain are the most effective irrigation methods during the germination stage.
• Upon germination, remove the dome and expose seedlings to full light.
• When adjacent seedling leaves are touching, transplant to your growing system. Be sure to completely saturate the roots and cubes at the time of transplanting.

Irrigation

• Once true leaves have emerged it is essential that a complete water-soluble nutrient formulated for the crop be supplied to the plants.
• Compared to other media, STG^® will generally require more frequent but shorter irrigation intervals.
• Once plants are placed in the growing system, the irrigation interval must allow the media to stay evenly moist throughout.
• In flood and drain systems, set the flood level to 1/4” to 1/2” below the top surface of the media.
• Should the media dry out, the media needs to be completely rehydrated by flooding and draining or thoroughly watering from the top.

Crop Production

• Vine crops and taller plants may require support in the form of staking or trellising sooner than with other types of media.
• Cover the surface of deeper containers (Bato buckets, Dutch Pots), with a solid cover to block light, preserve moisture and prevent algae growth.
