The only thing I don't like about peat pots is the roots have a barrier that slows growth down even with the bottom is pulled off. I used them for a couple of years outdoors but don't use them anymore. Heres are some cool season Indicas growing under the greenhouse shade clothe. The daily temps are in the 100sF or 40C the plants are suffering. They live under the shade clothe 24 hours a day.
