Heres some general info, I just treat mine like any other cactus.


SAN PEDRO
Trichocereus pachanoi Brit. & Rose;
Cactus family (Cactaceae)

A tall, columnar cactus growing to 18 feet, with six to eight ribs. The spines are small, sometimes nonexistent. The flowers are white, reddish-brown outside, up to 10 inches long, very fragrant, night-blooming. Native to Ecuador and Peru.

Cultivation and Propagation: San Pedro may be grown outdoors in the West and South or as a pot plant in the North. It prefers a sandy, well-drained soil. If potted it should be kept in a clay pot, as this will help the soil dry quickly and prevent root-rot. San Pedro is most easily propagated by cuttings. These should be dried for a few days to several weeks, until the cut surface forms a corky layer. The cutting should then be placed in damp sand, deep enough to support it. After several weeks, when the cactus begins to show signs of growth or swelling, it may be potted in ordinary cactus soil. Seeds are now becoming rare in this country. San Pedro enjoys full sunlight. Seedlings are more light-sensitive than mature plants. If they turn a reddish-brown color, place them in partial shade. Potted cacti should be turned occasionally, to expose all sides to the sun. They are also very sensitive to natural gas and should never be grown in a kitchen with a gas stove. One of the main sources of trouble with potted cacti is over-watering during the dormant months. In winter, the plants' rest period, they should only be watered enough to keep them from shriveling. In summer they may be watered often. San Pedro, like most cacti, tend to grow mostly during spring and summer. During the summer they send their roots deeper into the soil. At this time rootlets may appear at the base of upper branches. This is an ideal time to take cuttings.

I think what he meant was growing them in like agar or something. Personally I know jack shit about agar. Though I am fascinated by it, it's too damn complicated for my simple mind.

I was at a hydro shop in my city the other day and
noticed that they had some cactus under lights.

had 5 6 foot columnars that were only a year old...

18/6 all year.

never thought about cactus under lights.

probably too sunny here to justify...but interesting
nonetheless.

use the sun, light intensity goes by how much root structure they have, and how used to the sun they are. your problems could all be solved in the posts that i just deleted 2 seconds ago found here.

unfortunately, i live in an apartment, and i've got one window that faces west. they get some sun, but not enough. maybe if the window faced south it'd be a different story....

plus i want to have a few of them growing and that would just take up too much sill space from other plants.

i'm thinking that a mixed bank of cool white and warm light flouro's with some strategically placed reflective material could make things bright enough... or at least give them a lot more light than they'd get on my window sill in winter around here. (it's dark).

I'm really lucky in that all three of my windows face south. Two of them have heat vents directly above, so hot air is blown onto my cacti. I could easily rig up some tin foil to intensify the light, just too lazy right now.

But I feel for you, westward windows suck a big cigar and get cancer.
