Hydroponics, by definition, is a method of growing plants in a water based, nutrient rich solution. Hydroponics does not use soil, instead the root system is supported using an inert medium such as perlite, rockwool, clay pellets, peat moss, or vermiculite. Basically, there are six types of hydroponics system as listed below.
1. Deep Water Culture
2. Nutrient Film Technique
3. Ebb And Flow System
4. Wick System
5. Drip System
6. Aeroponics
SNAP ( simple nutrient addition program) hydroponics is a low-cost hydroponics system for soil-less vegetable production. It is best for home-based vegetable production and ideal for small spaces typical in urban area. It is simple to set-up, maintain and operate since it only requires enough sunlight, air movement and protection from rain. Aside from this, SNAP does not need electricity compared to other hydroponics system since it incorporates passive aeration of the nutrient solution used. The system is also inexpensive since about 90% of the supplies needed to set-up the system comes from recycled materials and it requires low manpower. Return of investment can be realized as early as in the first year of operation.
Using 'grass clippings tea' as fertilizer is already an old method by farmers in introducing a natural and organic form of fertilizer into their plants. This is rich in nitrogen which promotes lush growth and greener leaves. This tea fertilizer is best for leafy vegetables such as pechay ( Chinese white cabbage ), lettuce, kale and other leafy veggies.

Chinese white cabbage or also known as 'pechay' is very popular in almost all of households in the Phillipines. Pechay is easy to grow and very well recommended for those starting to grow their own vegetables. Pechay is normally harvested in about 30 - 45 days, but in this video, we can say that we can harvest our produce in as early as 24 days, from seed to harvest.
