I have taken clones started 16 8 to the flower room and then start to reduce in veg time 1 2 hour a week in 4 weeks most of the strains will show hairs between 14 and 13 hrs light.
Best light cycle for clones.
For clones and seedlings the lower wattage led units are the most efficient and effective choice.
There are two spectrums of light that plants need but the best light spectrum for clones is red and blue.
They ll also need 6 hours of darkness to help the roots grow.
The advanced light cycle for marijuana growing will save you time and money allowing for more quality plants and marijuana buds.
Clones need 18 hours of light to grow a strong stem and healthy leaves.
A power outage is one such event or if you need to unexpectedly change a light bulb.
More light makes clones root faster.
Which light cycle is best for vegetative growth is an often debated topic.
The light cycle for clones is simple.
Lights are on 24 hours and off 0 hours.
In the cannabis community light cycles are expressed as a fraction with lights on time over lights off time.
Advanced marijuana growing light cycle.
Cannabis light cycle basics.
Which light spectrum is the best for seedlings and clones is an ongoing debate.
If using fluorescent lights or cfls you can keep the light 1 or 2 inches over the top of the dome.
The light cycle for clones should be 18 hours on 6 hours off.
Cloning cannabis during flowering time cloning marijuana plants during the early stage of flowering is possible but in doing so expect that it will take a number of weeks to revert them back into the vegetative phase.
For plants currently on a 12 12 light cycle a power outage won t do any damage unless it lasted for days and days.
Once clones are well rooted place them under 12 12 or 18 6 light and dark cycle to induce them for flowering.
Usually giving me around 10 hrs light at the harvest.
As with hid lighting systems some of the higher wattage led are too intense for sensitive seedlings or clones.
The 24 grow light cycle will cause the mother plants and clones to grow at such a fast rate that it may become a problem with space and light.
Spectrum is another consideration with led.
Blue light helps the root system and red light helps with plant.
I get this question frequently so i decided to set up an experiment to demonstrate.
If using a horizontal 400w.
These things can interrupt your light cycle and can therefore have consequences for your plants.
Soon as i see the hairs i go 12 12 and even then after 2 weeks i start reducing 15 min a week til harvest.
I cut a tray of clones and started them inside the clone dome with my usual technique but this time i put them near a 4 bulb florescent t5 light fixture.
Now place the dome on the cloning tray with the new clones inside.
