1/3 worm castings is a bit much. they tend to run a bit hot and could cause your soild to stay a little water-logged. 10-15 percent would probably be good.

bio bizz makes a great soil. the all mix has nutrients in it, and the light mix doesn't. just buy a quality potting soil and don't worry about mixing your own. sunshine #4 is good too.

you definitley should go to a 1 gallon then a 3. reason being is that you want the top and bottom of your plant to grow at close to the same rate. if you go straight from a jiffy cube/pot to a 3 gallon your roots will grow faster than the top of your plant and you will eventually become rootbound with a small upper half. a good rule of thumb is one gallon of pot space per foot of stem height.

headshake Reviewed by headshake on . Soil mix and general questions So I have only grown once before in regular potting soil and used regular liquid ferts and did NOT ph adjust any water (just used filtered water) and surprisingly got 3ozs off my blueberry, 2oz's off vanilla kush and 1.5 ounces off super lemon haze all from jiffy pot to 3gal to 5gal pot. Problem tho was my vanilla kush came out with an insane amount of seeds and my lemon haze turned hermie but not quite as many seeds but terrible taste and not strong. Blueberry thankfully smokes grrrrrreeaaatt Rating: 5
