air movement inside the room is very important. strengthens stems and roots.
BobBong Reviewed by BobBong on . What causes weak stems? (laterstageofveg) I have been growing several different strains now, for a few months. They were stunted early on due to lack of light (12's) I have since upgraded to a 1000w cooltube. This last week they shot up, but the stems of new growth are very weak. Not brittle, but soft and floppy. Also, have twisted leaves. what's up with that?? I do have some pic's that I can post if it will help, but I figure someone probably has some reasoning behind weak/soft stems. Thanks everyone. Lazer. Rating: 5
