What can I use with roots organic 707
Any 2 or 3-part base nutrients should be just fine.
Depends on the size grow pot.
@Mr. Grow It 3 gallon
@deangelobaker1988 Well if you're trying to shove as many as possible in there then 9 will physically fit, but the plants would need to be very small and you'd spend more time watering and more money on soil with more containers. A more comfortable fit is 4 plants in a 3x3 and even then the plants will need to be on the smaller size. Hope that helps.
