What light have you found worked best to root clones???

23w daylight spectrum cfl per every tray or 2 of cuts.

used to hang one over my 60 site EZ cloner also.


u want weak light for fast roots bro... i agree with dude above, go cheap and spend ur money elsewhere in your setup


good luck.

tu shay.. couple old blue aquarium fluoros work for me.. temp is most important not light fwiw

So for some reason a few people think no light is an option? Seriously,? So you want your clones to induce flowering is what your saying?????

Maybe should have stated, when all conditions are correct, what is your light of choice for cloning!.

Thank you to the people who actually contributed..

i use coil cfl's. work fine.

Root zone temp seems the critical factor and type of light much less important from what I have seen

If it comes to cloning success rate, I agree with foomar. Temperature is more important than light. Too cold, nothing or extremely slow, too warm, rot and slime (at least with my cloning technique)

me three. i stick my finger down in the rooting medium to check temp. . as winter comes on keeping up off cold floor very important. i enclose my small veg, clone area and use the heat from the fixtures and lamps to keep temps up. fan and some ventilation still important. i spread a little of my super soil on top of my rooting medium so my microherd (includes rna archaea from sea-crop) can keep the cloning, seedling medium fungus free.

floros for rooting and first week in beer cups.. then to the T5s or 400w MH. mixed with floros.

Its well worth getting an old style mercury or medical type thermometer , the temp reading on most pH meters is innacurate and its about a 5 deg range from too slow to mush.

Thermostatic propagators have the same problem , bubblers hold the temp well using a small fish tank heater in a larger reservoir than usual.

Heating pads for brewing like the one that stands two wine demijohns on top are good and inexpensive , just check with a thermometer and adjust , adding a layer of paper or similar to lower transfer or a smaller reservoir to raise temps as required from seasonal variations in ambient.

The heating cables sold for fish tanks are more rugged than the glass type and ideal to drop in a bubbler or use in the bottom of trays with a media like perlite or compost.


Giving them a good stabbing seems to help.

this 2' tek-lamp from htgsupply.com works great for me, i use rapid rooter plugs and a humidity dome. the light hangs about 2 inches above dome so its real close to the cuttings. i have found that the cuttings root faster with the light very close. it might have to do with the heat the light emits even though its not much heat at all. the tek-2 is very energy efficient, costs me about +/- $10.00 a month to run this light 24/7 worth every penny to have fast roots. the only negative thing i have to say about this tek-2 lamp is the bulbs could last longer in my opinion, but i do run them 24/7/365 and i get 3 - 4 months max life span. the replacement bulbs are only $16 a pair so there relatively inexpensive. its a good light and works great for me, i also use a tek-2 for my mother plants.

Whatever rootzone heating source you are using, use a thermostat to switch it on and off when it is needed, keeping the rootzone at the preferred temp is always the right way to go.

If you interrupt the heater with a remote probe thermostat, stick the remote probe in your rooting medium exactly like a cutting stem, read the correct temp with a separate thermometer (as foomar says, many integral ones lie) and adjust to suit... Works perfectly 12 months a year... Temps never vary due to the surroundings...

Not sure if its for marking out stitch holes in leather , or a medical/BDSM gadget.

By luck its small enough to make many closely spaced indents in a few seconds and blunted to cause a small deliberate repeatable amount of damage.

Helps more with some other species and woodier stems that are harder to root than weed , pyracantha in ten days compared to six weeks by traditional methods.

Starting with three primary roots or thirty have not seen any obvious difference at harvest form or yield , and I autopsy every rootball.

Most of my cloning is done at 75F with indirect room lighting.

It's slow at around 2 weeks to show roots for most strains... but it's nearly 99.99% effective and makes for quite healthy clones.

Keep it Clean! :D

Best light for clones is a small 13w CFL, 2 ft above my diy bubble cloner, I just want the photo motor to just tick over until the roots show ....them its strait to veg and 400w Mh

Everyone talks about how important the root temperature is, and the equipment to read it, but no one states the degree desired. What should my root zone temp be? If I'm using an aero station, what temp should the water be? Clones will root in the dark and cold, so you can in fact clone in darkness without stimulating flowering as long as the ambient temperatures are lower than 45 degrees. What light cycles do you clone under?

t8 24/7
25 site ez cloner
fish tank heating element (sometimes I use it, sometimes I don't) basement grow 73* year round
5.8ph water
rooting hormone
73* tent temp
60% r/h
2.5 gal warm air humidifier

potted after 9 days (huge roots!!)
 
Used most types of lights or cloing but settled on Constant Color CMH from GE.
Retro White and Master Color from Phillips did not work quite as well.
Magnum and HydroGrow LED were also used, again, not the equal of GE Constant Color.

Unrooted clones get 75-100 umol and 150-200 when roots start.
About a meter from the plants with 400 watts with a white enamel reflector is approximate for new clones and 75 cm for newly rooted.

All the lights grew clones, GE just makes them a little greener.

I just learned about umols so this is really helpful thanks....I'm using t5s right now and 1000w hps on at 50 to 70% depending on how mature they are :ying::biggrin:
