Potting

I am wondering if i should add more soil underneath my plant the pots are fairly big themselves however there is only roughly 7 inches deep of soil for growth. Should i leave it at this or try to add more soil from the bottom i could go about another 2 inches higher. One of my plants is about 5 inches well into week two now!!

What size pot? You may want to go out and get a three or five gallon container and re-plant into that rather than trying to add soil to a pot that may be too small for full growth anyway. I'm no expert and I just puffed crucial bowl but thats my two-cents.

i must agree it is better to traspant into bigger port thenr to stress the roots by trying to fill from the bottoem just to transplant later anyway. why stress them twice

Just repot the plants into a larger container.
