Q:Buy vermiculite what are the notes, buy vermiculite to understand
First, buy vermiculite. What do you do with it?. General 1-3mm, 2-4mm culturing, succulents with 2-4mm 3-6mm, 3-6mm 5-8mm hatching vermiculite.
Q:Okay with the kind of plants are pure vermiculite
No, vermiculite is too light for the roots of plants. Usually mixed soil.
Q:What kind of stone is vermiculite?
It is such a name. Brown, yellow, vermiculite is dark green, like the oil sheen. After heating them into grey. Vermiculite can be used as construction materials, adsorbents, fire insulation materials, mechanical lubricant, soil conditioner and so on
Q:How much should the ratio of soil vermiculite to perlite be?
All kinds of flowers need different drainage, so the proportion is not the same. For example, cactus soil half, the other half can be conducive to drainage ventilation, prevent decay. If it's jasmine, then 7 pieces of soil and 3 others will do. You can make a flexible decision without a prescribed proportion.
Q:How do you grow your vermiculite? Do you place it at the top or bottom of the soil, or mixing?
The general clay soils rich in rot are the following:Leaf soilThis soil is usually grown by decaying and fermented leaves and weeds for a long time. We can find this kind of soil under the mountain woods.Garden soilIt's the soil in the garden. The content of organic matter in garden soil is much, and basically belongs to composite soil. It is relatively loose and drainage well. It is ideal for planting soil.Pond sludgeAs the name suggests, is the bottom of the pond mud pond sludge. The organic matter content of this mud is high, and its disadvantages are relatively sticky. It should be mixed with garden soil or rotten leaf soil for reuse.
Q:What are the main ingredients of vermiculite fireproof board?
Vermiculite fireproof board is a new kind of inorganic material. It is made of expanded vermiculite as main raw material and mixed with a certain proportion of inorganic binder.

Q:What is the difference between perlite and vermiculite and orchid stone?
Perlite brittle particles are commonly used substrates, vermiculite breathable water storage, orchid stone do not understand
Q:What is the thermal conductivity of vermiculite and vermiculite?
Vermiculite has higher layer charge number, so it has higher cation exchange capacity and stronger cation exchange adsorption capacity. Characteristics: light weight, and good adsorption properties, not decay, can be used for 3-5 years (unlike the humus, coconut shell, clothing and other perishable)
Q:Chinese rose with 6 days after the germination of vermiculite cuttings, is false living?
People engaged in nursery work know that cuttage is the main method of breeding rose flowers, not only can maintain the characteristics of fine varieties of roses, but also have high reproduction coefficient, short production cycle, little investment and quick effect. However, in the process of Chinese rose cutting, the phenomenon of "false living" often occurs because of lack of experience or improper method. In other words, when the rose cuttings for 5-10 days, cuttings on the axillary bud has been germinating or pumping leaves, it seems to have lived, but soon wilt and die.
