A frame Vertical Farming with planting gutter

A frame Vertical Farming with planting gutter is one of popular farming with substrate hydroponic system for lettuce, for growing strawberry.

Substrate types: including ceramsite, sand, gravel, vermiculite, perlite, foam, rock wool, rice chaff, some can be used alone, some mixed.  The substrate acts instead of soil to hold plants in place and hold nutrients and water.  

Management method: check regularly and add water in time.  Large plants should be watered every 10 days, and small plants should be watered every 10 to 15 days.  At the same time can use a few nutrient fluid or potassium of 2 hydrogen of phosphoric acid to mix in water, gush leaf reverse, if use organic compound fertilizer half spoon, apply on matrix, every month, the effect is very good also  .

Ceramsite, as the name suggests, is a particle of pottery.  Most of the appearance of ceramsite is round or oval sphere, but there are some imitation gravel ceramsite is not round or oval sphere, but irregular gravel.  
The shape of ceramsite varies from process to process.  Its surface is a hard shell, this shell is ceramicor enamel, which has the effect of water retention and gas retention, and gives the ceramicite a high strength.  
Because the production of ceramsite raw materials, ceramsite varieties are also a lot of, so the color is a lot of.  The color of roasted pottery is mostly dark red, ochre red, but also some special varieties are gray yellow, gray black, gray white, green gray and so on.  Due to the different solid wastes used, the color of non-fired ceramsite is different, generally gray and black, without gloss on the surface, not as smooth as roasted ceramsite.  
Ceramic particle size is generally 5 ~ 20㎜ maximum particle size is 25㎜.  Ceramsite is commonly used to replace gravel and pebbles in concrete.  
Light weight is the most important of ceramsite's many excellent properties and the main reason it can replace heavy sand.  The internal structure of ceramsite is characterized by fine honeycomb micropores.  The pores are closed, not connected
