Cloning under flower spectrum or veg spectrum

What is the correct spectrum for cloning?
Is there a dark period recommended?
Specific time to take cuts? (morning / night / midday)

You don't need much light but veg spectrum would be appropriate, I've cloned with as little as 20w of LED. Cloning is about building roots, they don't need much light at that stage.

I've tried almost everything and i've had a hard time with 10 clones near 0 success.
I've got a good plant topped and i'll be a little bummed if it doesn't grow roots since it's got plenty of energy to use.
I would like to be able to start with smaller clones though.

Some plants are hard to clone, some are easy. It all depends, after cloning a few times you will see what I mean.

We recently experimented with making clones under the Sunlight Systems 315w Light Emitting Ceramic (LEC). Got fantastic response from the babies. We left the light approximately 2-3' above the domes because we were concerned about too high light intensity. But the clones loved the LEC. Popped roots a few days sooner than under the T-5s. Growth rate seemed faster too. We've now moved to the LEC's exclusively for cloning.

Also like to give ya one key tip for cloning. Cloning is like drywall - you have to know when to stop and just back away. Here's what I mean - after you set up the clones in the dome, close the vents completely, mist the underside of the dome to get it wet, place the dome over the clones, put it under the light and BACK AWAY. Do not touch it for a week, Do not remove or raise the dome for ANY reason. The babies need 95% humidity to survive because they don't have roots yet. If you raise the dome for even an instant that humidity is compromised and the babies suffer. If you repeatedly lift the dome to "check" them you will have a really hard time making it work. I know it's tempting to try to "help" them but they simply need to be left alone.

After a week under the closed dome open the vents for a day or two and watch for new green growth at the tops. Hard to notice but you'll see it. Once you see the clones are beginning to grow a bit NOW remove the dome. Once removed the dome does not go back on.

Harden them up for a few days by leaving them under the lights in the open tray. Top water with a turkey baster once each day to keep the rock wool moist. In a few days they'll be ready for the next phase of life - transplant to your favorite medium and grow away!

Here's a recent clone using this method:

Oh, no wonder. It is like the old story of the mango seed. If the kid digs it up every day, he should not wonder why it did not root.

Guilty. I was too concerned about fresh air. Did too much checking.

I also noted that you didn't clip all the leaves down by 1/2 and you started with a large branched stem instead of a tiny tip, two things I have seen Cervantes recommend. So, not all his stuff is correct either.

I never tried that either, but it makes sense. They are trying to root. And a lot that happens early may be based on light cycle.
Where, during Veg and big growth it only depends on, feed, light and CO2.

I no roots develop In the dark cycles so maybe I should start cutying lights off for an 18/6 cycle for root growth as I have had 20 clones in a clones for like 3 weeks now and half have nubs to 1.5 inch roots and the other half has nothing so I will change light cycle tonight

Yes. Our philosophy is to start with as healthy a plant as possible. We use well-fed, vigorous mothers. We do not take away from what nature provided so we do not cut the leaves on the clones. Those leaves are needed more than ever after the clone is cut and it has no other means of survival. It needs those leaves. We do not want to compromise or diminish the plant's capability for photosynthesis.

As far as the branched clone goes, we've found that by starting with a branched specimen we can top early and gain as many as eight upright stalks with only one FIM exercise (on the two or more main stalks). More vertical stalks = better yield.

Not sure what you mean by the Cervantes observation.

Peace

I kinda typo along sometimes. These are the hands of the legend, George Cervantes and his signature swiss army knife. This is exactly the shot I refered to. He has this video where he shows himself picking clone shoots. "Yeah, these little tiny ones in the center of the plant that won't amount to anything."

After I take a little one, I guess for the tender stem, and then cut the leaves in half, I get nothing.



This is him again, "cloning."

Is that you, Doer? Your hands look like they are 80 years old.
