1.What is horticulture vermiculite
Horticultural vermiculite is a light, absorbent material that is chemically inert and odorless. It is made from flakes of a mica-like hydrated silicate of magnesium-aluminum-iron. The flakes are flash heated to 900 degrees centigrade. Water quickly evaporates as the vermiculite expands like an accordion. This process, known as exfoliation, balloons the flakes to twenty times their original size. With an essentially neutral pH of 7.0, horticultural vermiculite helps with soil aeration and retains moisture, fertilizers, other nutrients and plant treatments.

2.Horticulture vermiculite Benefits
Horticultural vermiculite is versatile, clean and sterile. While its neutral pH of 7.0 trends toward alkaline because of carbonates in the product, it does not have the pH lowering effect of peat. When combined with peat or composted pine bark, the resulting mix provides faster root growth. Because of its expanded size and light weight, it helps aerate mixes while retaining moisture and nutrients. Horticultural vermiculite is also used to bulk up mixes and lessen compaction.

6.Vermiculiteusege fr hoticulture
1>. Adding vermiculite to soil improves the airflow by preventing compaction,lighten the soil, assists in drainage and adds nutrients such as nitrogen and potassium.
2>. Adding coarse vermiculite to your gardening supplies can improve the overall growth of your plants
3>. Vermiculite is a naturally-occurring, lightweight silica-based mineral. Vermiculite is sterile, holds moisture well?? and comes in uniform granules. These properties make vermiculite ideal for germinating plant seeds. However, because vermiculite has no nutrient value, it is only suitable for growing seeds until they are 1 to 2 inches in height. After that point, the seedlings must be transplanted to a more nutritious mix that is roughly one-third vermiculite and two-thirds peat moss or compost

4.Perlite uses for horticulture
1>in horticultural applications ,perlite is used throughtout the world as a component of soilless growing mixes where it provides aeration and optimum moisture retention for superior plant growh.For rooting cuttings,100% perlite is used .studies have shown that outstanding yields are achieced with perlite hydroponic systems
2>other benefits of horticultural perlite are its neutral PH and the fact that it is sterile and weed-free .in addition ,its light weight makes it ideal for use in contaner growing
3>other horticultural applications for perlite are as a carrier for fertilizer ,herbicides and pesticides and for for pelletzing seed.Horticultural perlite is as useful to the home gardener as it is to the commercial frower .it is used with equal success in greenhouse growing ,landscaping applications and in the home in house plants
