I have a 4" fan i bought at wal-mart that i hang behind the bulb and it blows cool air directly over the bulb, seems to work pretty well for me, i dont really have temp issues and im running a 600w gull wing
When fan leaves become mature and ready to sacrifice themselves for the plant the stems often become purple, also if u bend the leaves around to tuck them away or out of the way of a bud site it can cause the stems to turn purple.
whats up guys? Yesterday my plants looked fine and when i take a look this morning i noticed on 2 of my mains on my cherry bomb, the pistils on the tops had dissapeared and theres a brown spot on the top now. Checked for nanners, didnt see any. It did get up to 90 degrees the other day and 88...
Still got some weeks buddy, wait for the hairs to begin to recede back into the calyxes, a scope would help alot if ur able to aqcuire one, $10-15 for properly harvested buds seems ideal.
