Cloning lights. - New Growers - International Cannagraphic Magazine Forums

I just made 4 cuttings from a 7 week old plant. I've read that flourescent lights are the way to go, but I have a 400W MH bulb in the veg tent and put the clones with new seedlings in a clear covered container for humidity retention. The plants are about 2 ft. from the light both vertically and horizontally. Is that too much light? the only flourescents I have are the regular 100W energy saver bulbs, but I have 2 hoods and the bulbs are rated 1,600 lum apiece. Would that be better for the time being?
Thanks for the help.

LESS light is better,...seriously, you can clone in the DARK.

if you blast the plant with too much light, you FORCE the plant into a higher level of chlorophyll production, which will need more water, and the plant wilts because it can't draw enough moisture from the little tiny slice in the stem, and a high level of moisture in the air with the dome.

go for a 22 watt COOL BLUE CFL with say no more than 1500 lumens (I personally use an 800 Lm cfl), and you'll get nice fat roots, and the thing will stay stiff.

(your 100w standard energy saver CFL's will be fine for now)

Personally I would not put clones under a 400W globe unless they are well rooted. The light is just to intense for them without roots. I would stick to the fluoros unless there is a shaded area in your veg area away from the 400W.

You are trying to encourage root growth not vegetative growth. Some form of bottom heat will also help.

Best of luck

A single 23 watter will serve several hundred clones from several feet away. If you want to use the 400, keep cuts as far away as possible and place a barrier in front of the clones to block direct light.

If you need a dome for cloning, that's one thing but, get the seedlings as far from high RH as you can ASAP! With short cuts and well trimmed leaves, I clone dome free in as low as 15% RH. High RH is deadly and, if you need it, it's generally a sign that something else is wrong.

I had trouble cloning with a 400W HID

for rooting i use a single 13w cfl for around 30 or so clones..once rooted i then throw them under a few 42w cfls and then off to the flower room which could be a 150, 250, 400 + hps

Use a flowering bulb for rooting, cool bulbs stimulate vegetative hormones and N uptake. Rooting uses P or K and enjoys the hormone increases from Warm bulbs, just like flowering.

I use 125 Watt CFL Warm low side of the Kelvin for rooting, then pop in a 125 Watt CFL cool mid Kelvin bulb when they have roots.

my bulbs are 13w warm with ornage glow and thats all i have ever used..then i go to a 26w cool or a few 42w cfls warm.. warm or cool blue or red and get great root growth eather way i go.

that's the EXACT opposite of what ed rosenthal taught us years ago.

care to post the info for this? or where this information came from?

not trying to start an argument, I'm just curious

I'm with reckon. Clones root best with a blue spectrum but with low light intensity as mentioned before. I recommend a 40 watt blue spectrum cfl in a big cardboard box with a computer fan mounted very close to the cfl at the top of the box. Then put a big hole in the bottom for an intake. put it on 24 hrs of light.

Remember to ignore cfl packaging and what they are called(eg.cool blue,cool white,...whatever)because they are not standardized so there is a lot of inconsistencies among manufacturers . Look directly at the "kelvin" to get direct "color temperature". Sylvania daylights are 3500k.....most others are 5000k...serious inconsistencies...

The higher the number of kelvin the cooler the shade!!!

@stoned_face: Dont root with hps takes twice as long due to spectrum. If your cutting are close enough to the light they wont even root. Low intensity remember.
