The preceding few weeks , the cultivation container at Inagro in Beitem ( Belgium ) was occupied by Sonsation and Sonata plants that are already raised before wintertime cultivation starts . If they were planted in mid - October , it would n’t be possible to grow them outside during the same year . Namely , in summer conditions they would n’t flower . The cultivation container allows for the computer simulation of different season disregardless of the outside climate . During lit wintertime refinement , Iterrreg will compare " tonic " plant from the container with 10 - month - old refrigerated planting material ( plants that were outdoors on the tray field last year and packed in December 2023 ) .
unlike phasesThe raising of plants take up berth in several phases to ensure the most focused and optimal growing of the June bearers .
form 1 : RootingOnce the cutting are placed into the substratum , they are encouraged to root in . Without theme , they are very susceptible to dehydration during the first few twenty-four hour period . A sufficiently high RH is achieved by obscure or covering with foil .
Phase 2 : the Vegetative phaseOnce rooted , the carving should acquire into sturdy plant . A vigorous summer climate with recollective 24-hour interval leads to speedy growing and production of new leaf . Phase 3 : the generative phaseJune - bearers only initiate flowers when mean solar day distance becomes shorter ( on the tray field from the beginning of September ) . Without flowers , clusters do not egress in the output phase and can not be cull . For this ground , the container little - day conditions and early autumn during this third form .
Phase four : HardeningOnce the industrial plant have enough efflorescence , and achieve the desire microscope stage of development , the tray plant are bit by bit cooled to make them for cold warehousing at -1 ° C . To control sufficiently thick temperature reduction ( up to 7 ° C ) , the plants move from the finish container to a refrigerated room equipped for this purpose . SonsationUsing lit cultivation container is not the only method that can fetch about June - bearers with early flower turn - over . Another way to have the plant see scant - daylight conditions is to by artificial means darken the growing environment .
For spring polish that will start in other December in the glasshouse , there was a need for Sonsation industrial plant that have flowered early and that are ready by mid - October . This permit them to still go through their lower limit required identification number of stale hours ( six weeks ) .
In early June , Sonsation was grow on Inagro ’s tray field with the aim of testing the effect of three darkening methods on flowering . The comparison will be made with planting material that has been in the electric refrigerator since December 2023 ; plant that can be expected to gradually run out of reserve . occultation is not yet a standard drill , but has potential drop if it performs at least as well as the long - chilled plants . The economical lend value of blackening is that long refrigerated storage can be avoided , potentially lead to greater yield and a more vigorous flora .
Lighting has picayune effect on rootle , but affects floweringThe culture container at Beitem has an ebb - and - menstruation system of rules to irrigate the plant . This is different from the tray field where the industrial plant are watered by means of overhead irrigation . In old trial , it was found that indoor rooting was more difficult and that cuttings often dried out . As a solution , the cut were breed with a hydrofoil during the first week to ensure high humidity which specify evaporation .
In addition , it was learned that certain igniter would also stimulate rooting . Therefore , in June , Interreg enquire whether different light intensities and spectra could accelerate up root . For the time being , the trial did not get a light recipe that achieved a strong root system quicker . However , it was noticed that flowering differed greatly between treatments . The effect of dissimilar lighting strategies on blossom control in fresh eyesores will therefore also be test in the coming week .
