Thank you newgrowbox for the co2 recipe, immaking that for sure.
im probably gonna do soil for my first grow
if you do soil, use BIG pots, with plenty of drain holes, put at least 1" of railway gravel or volcanic pumice stone in the bottom.
to keep the bottom of the pot out of your runoff, a dishpan with 1" of gravel on the bottom, and a drain tube in the bottom corner leading to a milk jug or other small mouthed, wide bottomed vessel is best.
catch the runoff and dump it (dont use it again, it will contain salt and shit)
if your pot sits in wetness you get rootrot, if you have too much water sittin about youll get humidity, then mould and budrot.
water only when you can poke a finger in the dirt without feeling dampness.
use fertilizers at 1/4 the rate recomended by the package and increase it slowly.
clay/terracotta pots are always better than plastic.
if your soil starts to smell bad, repot your pot with fresh dirt immediately.
heres how ya do that:
1) do not water for at least 24 hours before repotting! (otherwise youll be wallowing in mud)
2) lay out a tarp, or dropcloth in a big area! (youll want to do this inside, away from prying eyes)
3) grab the main stem firmly with one hand and the pot-bottom with the other, tip the pot and plant on their side on the tarp, and drag the plant out of the pot
4) firmly massage the dirt and muck out of the roots from the bottom of the rootball upwards. catch it all on the tarp
5) use a toilet bowl brush (i have one JUST FOR MY GARDEN!) to clean out the pot, and add more gravel (dont use the old gravel again but save it) and a few inches of fresh soil
6) stick your plant in the pot and gently pack more fresh soil around the roots, not too tight, and fill to 1/2 inch below the top of the pot. leaving a fist sized hole in one side of the dirt (youll see)
7) place an open sandwich bag (or similar) in the fist sized hole, and pour in dirt (pack it snug!) then fill the dirt-bag with water till it almost comes out the top into your main soil area.
use a knitting needle, piece of a coat hanger, or a chopstick to poke a hole in the dirtbag from above at an angle. lightly water the main soil area regularly but keep the dirtbag very wet for a week. you should NOT see runoff !
9) when the plant has recovered and the soil is uniformly moist but not wet, pull out the dirtbag and dispose of it. now your plant will be happy, and you wont need to fertilize for a month or more
Cleanup: take the tarp and it's contents to the lawn, hose the soil into the lawn, but save to gravel. put it in a shallow pan and let it sit in the sun for a few days, then you can use it again.
and also, i too will try that yeast culture. it's such a simple and obvious solution, it could only be produced from a true genius.
