The first stage of development of grassy plants, from germination before occurrence of the second pair the present leaves, marking itself the beginning of a stage of growth. At a hemp passes for some days in this connection on an open ground not always it is possible to make . From located between cotyledons first pair of the present leaves consisting from wide, pointed to end and jagged along the edges of plate develops. Then cotyledons wither and fall down, and from a bosom of the first pair there is second pair of the present leaves consisting of three blades. Thus the stalk should be within 5-10 see

If it is not enough light, he grows more long, that further can is negative affect its durability. In hothouse conditions this lack is easy for correcting - enough to establish a reflector or to place pots is more spacious.

On an open ground at growth of shoots above 10 sm it is necessary to thin out plants. Fructification Fructification - the period of a life of plants in which there is a formation and distribution of seeds. Hemp fruits - seeds of the oval form in a rigid two-folding cover - develop from the pollinated pistillate flowers and ripen within 30-60 days. Maturing occurs non-uniformly on inflorescence height, and rupture between its beginning and the end can make from 25 till 40 days.

The ripened seeds are showered on the earth, winter under a layer of leaves and stalks, and give new shoots in the spring.

plants soon dry up and die. In fructification the maximum is required to a hemp?, necessary for formation and maturing of seeds; requirement for nitrogen? And phosphorus?, On the contrary, a little bit more low, than during the previous periods. However top dressing is expedient for applying only when signs of potash insufficiency are appreciable. Much more important problem during this period - protection of plants against birds, mice and rats which can cause a considerable damage to a crop.

It is not less important to have time to reap a crop while the majority of seeds has already ripened, but has not had time to be showered yet. Cleaning of a hemp (on a fibre and seeds) is made for bilaterial use at maturing not less than 70 % of 80 % of seeds; at fuller maturing begins plentiful . With the fructification beginning a psychotropic cannabis the THC containing in inflorescences and leaves of a hemp, gradually decays, turning to much less active cannabis . At not impregnated plants the maintenance the THC does not decrease; of colours are formed , which then develop in false seeds (see Germination of seeds Germination of seeds of a hemp demands a moisture, oxygen and heat.

The first and the second is provided with properties of soil (humidity, friability of the top layer), the third - soil temperature (not more low +8. At germination seeds absorb about 50 % of a moisture on absolutely dry weight, duration of swelling about 40 hours. Reference temperature of germination +1. After absorption of a moisture from a seed the back gets under way and goes deep into soil, and then on a surface leave fleshy oval or cotyledons which quickly turn green.

The sprouted hemp maintains frosts to 4oC, at 6oC the majority of plants perishes. From crops before occurrence of shoots there pass approximately 10 days, the necessary sum of daily average temperatures nearby 120oC. Flowering of man’s and female plants of a hemp Flowering of man’s and female plants of a hemp (see and ) occurs in different terms. Man’s plants usually start to blossom in 8-9 weeks after crops. Terms of their flowering practically do not depend on duration of light day, they cannot neither be slowed down, nor to accelerate. In cases when presence of man’s plants on a site is undesirable, they need to be removed before flowers will be dismissed. Flowering of female plants begins for two four weeks later, than at man’s (at grades - almost simultaneously). Flowering terms are influenced by duration of dark time of days: usually starts to blossom, when night is extended more than at 1 o’clock (in an average strip of Russia - the beginning of August). In the conditions of a hothouse flowering can be accelerated or slowed down by change of duration of continuous illumination. Flowering in this case begins in 8-14 days after installation of the necessary light mode. In some weeks from the flowering beginning on female plants seeds start to be fastened.

From the beginning of flowering before maturing of seeds there passes about 60 days, the necessary sum of daily average temperatures of air about 1100 wasps.
