Een korte presentatie gehouden op een avond in Drenthe - georganiseerd vanuit het project DuurSaam GlasHelder - over het waarom en hoe ten aanzien van biologische bestrijding in de glastuinbouw
The 3 most important learning points of 5 years Cannabis Consultancy.pdfRené Corsten
This document outlines the 3 most important learning points from 5 years of cannabis consultancy:
1. Mistakes in starting material like cuttings can negatively impact the entire cultivation cycle. It is important to use anatomically equal cuttings from multiple weekly pickings that are stored and treated properly.
2. Increasing yield by 25% is possible through a faster growing cycle with a shorter vegetative stage and more cycles per year.
3. Flower shape and chemical composition can be manipulated using bio-stimulants, especially in soil-less systems, but a natural substrate is important for their effects. The goal is to optimize cannabinoid, oil and terpene production rather than focusing only on flower
Optimizing production of medicinal cannabis greentech 2021 09-29René Corsten
This document discusses optimizing the production of medicinal cannabis by balancing energy, water, and assimilate levels in the plant. It states that optimal production starts with a perfect assimilate balance between photosynthesis and respiration. Higher temperatures increase respiration and decrease the net assimilate balance available for plant growth, making the plant more susceptible to disease. Maintaining proper CO2, light, and temperature levels as well as stimulating nighttime evaporation to transport calcium to flowers can help balance assimilation and respiration for strong, resilient cannabis plants. The author notes there is more to discuss on these topics and announces a new research project on medicinal cannabis cultivation.

How to optimize the growing and production of medicinal cannabis? And what is the importance of the 24hour temperature of your growing room / greenhouse in relation to the amount of light?
Weerbaar telen – waarom en hoe toe te passen in de glastuinbouw?René Corsten
Wat zijn de mogelijkheden van weerbaar telen in de praktijk. Waar rekening mee te houden, hoe dit vorm te geven.
What are the possibilities of growing horticultural crops with the use of less chemicals and using natural defense.

10. Een korte chronologie chrysant
Tot 1990: minimaal 1x per week een
cocktail van middelen
1990: NTS gewasbeschermingsproject
1995: project geleide bestrijding
16. Wat is nu de lijn? Wat is er beschikbaar?
Natuurlijke vijanden
Biorationals
Hulpstoffen
Weerbaar Telen /
Systeem denken
17. Wat is van belang bij de optimalisatie
biologische/geïntegreerde bestrijding?
Kennis van de ziekten+plagen in uw gewas
Goede ondersteuning vanuit een toeleverancier /
consultant
Weten welke bestrijder het goed in uw gewas
doet – de 2e generatie is effectiever dan de door
u ingezette 1e generatie – Eventueel uitvinden
door middel van trial en error
18. Wat is van belang bij de optimalisatie
biologische/geïntegreerde bestrijding?
Denk in systemen - systeemaanpak
Maak een plan van aanpak
Start met een proef – op beperkte
oppervlakte/schaal
→ Wacht niet totdat u moet!
