Fluorescent and Compact Fluorescent Lighting (CFL)
These bulbs have their place in any indoor grow room. I tend to root cuttings under small 21 watt blue CFL
bulbs from General Electrics (GE), and I always like to keep freshly planted cuttings, as well as mother and
father clones, under fluorescent lighting too. For these purposes I also tend to favor the bluer or “cooler”
bulb spectrums, as I believe it helps the plants to grow roots faster than the redder or “warmer” spectrum.
Under these light sources, the plant's metabolism will be slower than under HID lights, which is why they
are ideal for longer-term clones that you don't want growing particularly quickly.
I use CFLs to root cuttings, with the cooler spectrum being my preference
Sprouting and vegging under HID and LED bulbs will really increase your growth rates and add to your
yields at the end as well. I recommend Blue Halides for these purposes, depending on your specific needs

REV'S TIP
In my experience, HID lights are NOT a good choice for rooting cuttings.
Cloning for TLO
There are almost as many ways to clone as there are ways to grow cannabis. I personally am a huge fan of
the aeroponic and bubble cloner methods. My friends have cloned in peat pots (Jiffy Pots) successfully, and
I have used perlite and vermiculite as well as Rockwool many times in the past. I never have needed any
