plant training

this indoor cannabis plant has not been trained , growing in natural christmas tree shape common untrained cannabis indica.

the modification of plant s growth habit called training. indoor cultivators employ many training techniques encourage shorter plants , denser canopy growth. example, unless crop large extensively pruned, cultivators remove adventitious growth shoots, called suckers, near bottom of plant and/or receive little light , produce poor quality buds. cultivators employ plant training techniques increase yields indoors:

topping

topping removal of top of apical meristem (dominant central stem), called apex or terminal bud, transfer apical dominance (the tendency apex grow more rapidly rest of plant) shoots emanating 2 nodes beneath pruning cut. process can repeated on 1 or both of 2 new meristems, when become apically dominant, same results. process can repeated nigh infinitely, over-diffusion of apical dominance produces smaller, lower quality buds, done no more few times. topping causes more rapid growth of of branches below cut while plant heals.

pinching

pinching (also called fiming ) similar topping in causes lower branches grow more rapidly, apical meristem maintain apical dominance, useful if plant has been topped. pinching performed firmly pinching apical meristem(s) substantially damage vascular , structural cells without totally breaking stem. causes lower limbs grow more rapidly while pinched tissue heals, after time stem resumes apical dominance.

these indoor cannabis plants trained grow flat in order take better advantage of grow lights , increase yields.


lst ing

lst stands low stress training , form of supercropping, many times referred lst super-cropping. technique involves bending , tying plants branches manipulate plant more preferred growth shape. method of training works indoor growers need illuminate plants using overhead lights. since light intensity diminishes increased distance (inverse-square law), lst ing can used keep growth tips (meristems) @ same distance light , can achieve optimal light exposure. lst can used in conjunction topping, since topping increases axial growth (side shoots). topping done few weeks before beginning lst ing. training works changing distribution of hormones—more auxins—in plant. lst ing resembles training of grape vines support lattices. outdoor gardeners employ training techniques keep plants becoming vertical.

sog

in contrast screen of green method, sea of green (or sog) growing depends on high density of plants (as high 60 per square metre or 6 per square foot) create uniformity in crop. in technique, grown in hydroponic media, colas of plants harvested. containers used enforce geometric distribution of flowers , plant material, exposure lighting , atmosphere. sea of green popular commercial cultivators, minimizes amount of time plant spends in vegetative stage, , allows efficient light distribution, keeping plants closer lights when grown full size.

scrog

scrog, short screen of green, advanced training technique cultivating cannabis, indoors. closely resembles sog (or sea of green) difference being scrog uses extensive training produce same field of bud effect 1 plant. medical growers may find helpful technique maximize harvest if allowed number of plants. screen such chicken wire hung on plants tips of branches kept @ same level. allows light distribution of nodes/bud sites. once flowering stage begins, flower tips reach through wire , @ relatively equal distances light source.

vegetative state: plant should remain in vegetative state until 70 80 percent of net full. branch reaches 7.5 10 centimetres (3–4 in) above wire pulled under wire , trained grow horizontally until flowering. because of amount of plant required fill net, vegetative period may require longer normal ready flowering.

timing: timing vital success of scrog grow. if net not full @ harvest, valuable space has been wasted. if net full buds crowded develop properly. knowing how plant grows can visualize when flower maximum effect.
