Hey chaotic, since I last talked to you I started 2 more seeds. And one is HUGE. Started on Aug 20, I planted it in a 2litre bottle, and the first true leaves are almost touching both sides of the bottle and are a nice dark green. And the second true leaves and halfway grown also! Im very pleased with this one so far. So today Im trying to make the ghetto co2 with yiest, sugar, and water. Im using a 20fl oz coke bottle. So my question is I have looked online for the perfect measurement for this and there are only directions for 2 litre bottles not 20fl oz bottles, would you know what measurements of the ingrediants I should use for this scale? Sorry for the spelling lol.
