san pedro...

i recently got a ~7" cutting of san pedro and am in the process of rooting it. im just wondering if/how often/how much i should water the bottom of the pot its in. is there any way to tell if things are moving along properly? since i put it in the soil the very top of the cactus has become somewhat lighter green but aside from that i havent noticed any changes in its appearance. also, im using a 100w compact fluorescent light, is that enough for the cactus or should i look into something stronger? ive just been keeping it at a 12/12 cycle because as of right now i dont have a timer and that fits easiest with my schedule. i'll try to get a couple pics up if that helps any, all ive got is a relatively shitty webcam though, so bare with me. im just looking for any suggestions, i dont have any experience with cacti so sharing any experience is a help. thanks

Just a warning, not being patient and watering in any way too much can easily result in rot. They can shoot out roots laying out of soil, so water isnt that necessary. That light will not provide good growth, but I have no idea how it will work for rooting.

Personally, Id let it throw roots on its own and then stick it in a pot. Its worked very well for me. Then water infrequently untill the growing season starts back up or you get some much stronger lights. Best of luck.

while rooting? cactus dont need much water, and it will most likely just rot. I'd say none... maybe a tiny tiny bit moist... it's supposed to be looking for water...

yeah, im not saying just water them. ive read somewhere that if you water just a bit from the bottom (put the pot in another container and put a small amount of water in the container to get just the bottom of the soil moist) it helps the cactus grow roots faster or something. i dunno, maybe i made it up. thanks for the responses though. as for the light, what kind and how much power do i need?

Wrong, the 100 W compact fluorescent fixture will provide excellent growth. I'm growing T. pachanoi under two 95 W compact fluorescents and have gotten a foot of growth during the growing season. You can't do much better than that.
You probably have a higher-lumen bulb which puts out almost as much light as my two 95 W bulbs combined.

It may have gotten a foot of growth, but I bet its on the thin side. A better light will give you much thicker growth which is what most people want. Edit: MH lights do not cost that much, and they work great for cacti if you can't keep them outside in good sun. My buddy got a 400w MH light for like $60 shipped w/bulb on Ebay.

All of that new growth will not contain very much mescaline. It's not about how fast the cactus grows it is about the quality of light. Mescaline content will be very low with artifical or even filtered sunlight. I knew a guy who had a cactus nersury he had tons of san pedro. He said that the only way the cactus will produce a decent amount of mescaline is to have it grow in Direct sunlight. He said that if the UV light is filtered the mescaline will be low. So if a greenhouse tarp filter is not enough light then I am sure that no "grow' light will do. Come on, San pedro isn't reefer. You can't just get a cactus and expect to trip anytime soon. It takes a few years of the cactus to get to know you first. When i first got my cutting from that guy i mentioned, the spines were more defensive in nature. After time when the cactus accepts yuo the spines will become less defensive. I can't prove it. It's just an observation.

what about a blacklight for UV light?

http://members.misty.com/don/uvbulb.html -in general: Wavelengths from about 345 to 400 nM are used for "Blacklight" effects (causing many fluorescent objects to glow) and are usually very slightly visible if isolated from more visible wavelengths -incandescent: Longer UVA wavelengths get through the glass and are not blocked by the dark colored filter dye -fluorescent: -BLB- These tubes emit lots of UV mainly between 350 and 375 nanometers, some of the 404.7 and dimmer 407.8 nM violet mercury lines, and just enough of the blue 435.8 nM mercury line to have a basically blue color when lit -deep-blue-violet- lamp with no phosphor and made with special glass (maybe quartz) to transmit the 253.7 nM UVC (shortwave UV) mercury line. These lamps are generally used to make fluorescent rocks glow -BL and the similar 350BL- The 350BL has a broader spectrum peaking at a slightly shorter wavelength (350 nanometers) than the BL does, and is supposedly more attractive to insects than the BL 'beehive' (high pressure mercury): The high pressure mercury spectrum includes a strong cluster of lines in the 355-356 nanometer range

No, there was absolutely zero stretching (etoliation) with my Trichocereus plants.

Also, the information posted about fluorescent lights is correct, but we're talking about compact fluorescent lights which have different characteristics such as much higher lumens.
http://www.ecogrow.com/index.cfm?page=26
A 190 W configuration provides 17,800 lumens which is comparable to MH but the reason I use them is that they generate far less heat (no fans needed) and are just warm to the touch. You can place your plants far closer to the bulbs. My understanding is that brightness varies as the square of distance, so spacing is important.

the bulb i have actually uses only 23 watts but produces ~1500 lumens and is said to be a suitable substitute for a 100 watt incandescent. so i was confused in the first place, second, compared to a 100 watt MH putting out an average of 6800 lumens, a 23 watt CF puts out ~22% the lumens using about ~20% the power. so really the only difference is the heat they produce and maybe the spectrum. both CF and MH are more efficient than HPS lights though, a 100 watt HPS produces only ~4170 lumens. i dont really know what makes a good light when it comes to plants though, any one care enough to share and save me some research?

Actually I do find that Pedros do respond alot to enviroment. For instance they get splotchy when it cools a bit, and their color comes back when it warms, plus with some whitish tint. For come reason I'm always thinking that the whitish tint is the mescaline. Maybe someone else know.

"so really the only difference is the heat they produce and maybe the spectrum."
The spectrum is a real big factor, I would even go to say that it matters more than how many lumens because it doesnt matter how many lumens you have if it is in a spectrum that your plant can't absorb. MH have a spectrum that is great for vegitative growth while HPS has a spectrum for flowering, and Flouros can vary.

yeah, as you can probably tell i dont really know anything about lighting and plants. so a MH would probably be good for a cactus? ~how many watts do i need?

The compact fluorescent bulbs sold at the link I posted are sold at specific color temperatures.
Other fluorescents will vary, as you said.
