Herpchat, to make a long story really short:
- 2litter bottle at 1.020 s.g.
- Add an air pump (no airstones, I use silicone tubing with 1/4
hard tubing so it reaches bottom of bottle)
- You want no contaminations so an air filter is prefered on the
pump, and small piece of cotton (I use rite size filter, cut really
small) with the airline stuck through it to block the bottle
opening.
- add light, (cheap clamp light from homedepot is fine, I use a
6500k light on mine, also from HD)
- Add phyto and wait about 10 days.
shake bottle up every few days to dislodge any settling particles.
And split culture after 10 days, or when it stops getting any greener (or browner depending on the cultured species)
It really is quit simple.
