Lol. They only stayed in the seven inch pots about a week. I was having to water too much after that. They r now in twelve inch pots. I have not decided if I want to chop on them anymore or not. I was thinking of just trimming off some lower growth. To be honest I do not have much experience with trimming. I let my last plants just grow without trimming to see what it would do and thought is just top these once and remove lower growth and see how that goes. I'm using a t5 so lower growth has turned out subpar. As far as the soil goes I just use ffof just like it comes. I will cut the bottom off these pots and place them inside another pot the same size filled about 3/4 full before I put them on 12/12 I use the fox farm nutes and pretty much follow their chart. One thing is for sure. When I turn off the fan these girls stink like crazy. Lol.
