1. Higher germination percentage
The improved shape and depth of the seed hole ensure that each seed rolls easily into the centre of the plug, giving a lower risk of dehydration and allowing the seed to be covered with an even layer of vermiculite.
2. Greater plant uniformity
The seedlings root quickly and anchor well into the centre of the plug leading to greater uniformity in plant development and fewer twisted seedlings.
3. Better plant quality
The new technology facilitates superior water and air management, which results in a better distribution of water and EC throughout the entire plug, resulting in better root formation and better, more uniform plant growth.
4. Improved ease of handling
The plugs can be removed from the trays and replaced with ultimate precision during selection. The plug height of 27 mm creates a larger volume that is beneficial for plant growth. During selection, fewer plants will be lost and the plants for transplantation into blocks maintain their maximum quality.
5. Sustainable water and nutrient consumption
The larger volume offered by the plug gives higher absolute water content in the plugs leading to a lower irrigation frequency. For propagators this translates to sustainable and more efficient use of water and nutrients and lower costs.
The beauty of the product is even though the tray is quite large and would be idea for commercial use, for the home grower it fortunately is a bit large. but I cut the tray into 20 pug sections ideal ! Seed germination of maize, tomatoes and lettuce occurred in 3 days with a single deep soak of the plugs.
I am very impressed with this tray and await my planted seeds germanation impatiently. The removable rockwool plug makes transplanting so much easier. Will no just purchase the plugs in future.
The French tray is easy to use and my tray floating on a pond inside a hot house has germinated COS lettuce seed in a week. Great Idea!!
