Hello,

I have 3 different lightbulbs and I need to know which one to use. I have an incandescent light bulb that is 60W and is a "heat lamp" bulb suggested for reptiles so I'm pretty sure it emits UVA and UVB light. I also have a "sun glo" 40W daylight lamp for reptiles it is a "Neodymium" lamp which filters out the yellow light and makes a whiter light. It also emits UVA light. Then my third option is a light that I found in the garage. It's a 23W spiral type looking bulb so I'm assuming its a fluerecent bulb? It's light is REALLY bright and it gives off a white light/kinda yellow. I have a sprouting plant that is 4 days old and its getting really tall. Most likely from improper light. I had the 60W heat lamp bulb on it for the past 2 days and it got tall so then I found the spiral bulb and switched it to that one and put it on today. I also got more dirt and gave the plant a turtle neck with dirt lol. So hopefully the spiral bulb IS a flurescent light.

Any ideas on which light to use would be great!

Thanks

you have two incandescent lights and one CFL. the neodymium lamp is a incandescent bulb with special glass. use the CFL, the others will only heat up your grow space(good for reptiles, not so good for plants). the single 23w CFL will get your through the vegging phase but wont be enough to flower nice dense buds.

Incandescents just won't do the job. You can believe us. Stick with the fluro til you get your act together. Mine are less than 1/2" from the lights. No stretch.

OK, the 'heat lamp' is on the other end of the spctrum from UV (a or B) 'heat" is in the IR (infra red,; aka: past the red spectrum)

Heat lamps and incandescent lamps (that don't' need ballasts, ie: Metal Halide (for veg) and High Pressure Sodium (for flowering) are no-good. Standard shop lights are better Light and heat-wise. (at least for vegetation stage)

The spiral bulb, is a cfl. Considered ok. But its spectrum is subject. What the 'color temp'? (you can x-ref the part number on the MFG's website) Typically you want 6500K for the veg stage and 2700K for flowering stage.


Some basic myths:
Pot likes it HOT. Nope 78F is ideal
Pot likes it Humid. Nope, 40-60% for veg and less for flowering (mold is BAD)
Pot is a weed and doesn't care. (kinda true. I can grow tomatoes with little care, but with some basic care I get killer fruit!)

Im running outdoor in so cal while the suns out and then an additional couple hours indoor with a lamp. Will and 850 lumans LED bulb suffice or do I need something that gives off heat because the plants seemed to stretch in the soon and then begin to sag more under the LED
