what do i need to do to make them more suitable for growing? my grow cab is small and i need something narrow to fit in there and 2/3 liter soda bottles are my best bet i think. should i just cover them in aluminum tape and drill holes in the bottom? i know roots arent supposed to see light but i dunno if the metal tape will make the root area too hot or something
anyone ever used 2liter soda bottles as pots?

2 liter bottle w/ top cut off and holes poked in bottom= 1/2 gal pot.
I've made pots with less... ha ha

light never bothered my roots when i used them. but i packed them close together.

ive done it, if your doing a small SOG theyre perfect, just cut the tops off and make plenty of holes in the bottom

as said cut the tops off and poke holes in the bottom, i use a soldering iron for poking the holes (typically put in 10 you will understand where when you do it) and then i throw one hole up where i want to cut the top off at, this way i have a starting point for using scissors to cut the top of so i have a nice even top, instead of ragged if i used a knife.
as for covering the side i have found that it hasn't really effected the roots, the bonus is you get to see the roots, but if worried just leave the labels on.
but if you cut just where the top starts to go in (about 8" total height) you will have approximately 1.6-1.7liters (approx 56oz) of soil space with it having about 1cm or so of empty space on the top, which is about equivalent to a standard 5"x5" nursery pot due to there shorter height.
oh and actual width is right around 4.125" which could mess someone up if there making a very tight fitting cab.
also the dunk method seems to work best for watering in my opinion

you get a bucket/container fill it with your water/nutrient water mix, and then you take your whole pot/bottle and but it in the bucket, (i use a 2.5gal square bucket that fits 4 2liters perfectly), then i let them sit there floating in the water till they sink to a point where water is coming up through the soil, but not over the lip of the bottle cause if that happens dirt/perlite particles start floating in your water cause the whole plant then sinks (while its not a problem in can be a pain if trying to keep the outside of your containers clean)
this ensure that the whole medium in the pot is thoroughly watered and forces any of the old air out the top, you can speed this up by holding the pot below the water line as letting them sit there takes forever, and then you just put them in another bucket/tray to drain before throwing them back under your light, but doing it this way i find you typically dont have to water for a couple extra days vs just regular watering,

Rambro, yes it's fine to bury the stem. It will grow roots just like a clone does in soil.
I really like the double big gulp cup from 7-11..until they're big enough for 2 gall trash cans
they make good pots if ur limited on width (floor space) but u have height to spare. I just tried it recently cuz i couldn't find tall thin pots (floorspace issue in veg). It's nice they grow plenty of roots very deep.
just paint it or duct tape so its not clear.
