Is cannabis a short day or long day plant?
Cannabis is considered to be a short-day plant, but there are some auto-flowering genotypes available. Short-day plants require a long, uninterrupted dark period to induce flowering; this dark period is considered to be more important than the light period itself (Lumsden and Vince-Prue, 1984).
Does Topping increase yield?
Does topping really increase yield. Some people claim topping does not actually increase yield, because the colas get smaller every time you top. But, it has been shown that the cumulative yield is much heavier when you top your plants. So yes, topping really increases yield.
When should I change my light cycle to 12 12?
Height of plant: Depending on the strain, plants will generally double in size during flowering. So, if ‘room’ height is limited, the switch to 12/12 will need to be done no later than when the plant has reached 50% of the ‘available’ height (remember to consider the minimum gap distance between lamp and foliage).
Should I cut off fan leaves during flowering?
Yes you should – but with the correct technique. A proper thinning will remove 20-40% of the mid to upper foliage every 5-7 days. Removing these fan leaves opens up light and produces better air exchange to the lower canopy.
Does Lollipopping increase yield?
Many growers have increased yields by lollipopping. We know enough about plant science to support the logic behind this type of pruning. What’s even cooler is that you can combine lollipopping with topping or fimming.
Do cannabis strains grow faster in the first weeks of flowering?
In these first weeks of flowering, many cannabis strains may indeed undergo a considerable growth stretch. This is important to know when it comes to feeding your plants properly, but also if you want to give them sufficient space to grow. In the very first weeks of flowering, your cannabis plants will be in the transition stage.
How long does it take for a sativa plant to flower?
Sativa strains of cannabis plants are often tall easily reaching upwards of 15-20 feet and produce smaller more spindly buds. Because the Sativa plants require so much energy to achieve such a height, they will also need a longer vegetative and flowering stage period. Sativa Flowering Time: 10 – 12 weeks.
How long does it take for cannabis to flower?
Not all cannabis strains require the same amount of time for their flowering, but many varieties will be ready to harvest in these last three weeks. There are, however, not too many strains that will be ready before week 8.
How long does it take for cannabis to stop growing?
Three weeks into the cannabis flowering stages, your pot plants will continue to slow their upward growth and, eventually, come to a complete halt.
