I just bought a 2' deep x 4' wide x 7' tall grow tent and want to use my 1000 watter using a "cool tube" reflector with a 560 cfm cooling fan. My question is, will this light setup still be too hot for the growing area? I have no experience with cool tube reflectors.
After 5 weeks of veg I am noticing the leaves are turning yellow and I am wondering if the roots are choking out because I used too small of a grow pot. Could that be my problem? If so, can they be transplanted to a larger pot if needed without harm to the plants?
The reason why I must raise the ON time is because if I only lower the OFF time that means it would have to shut OFF at 4:00pm. However, I cannot make it home from work to close the closet door to make complete darkness. So that's why I am happy you guys are telling me it's ok to raise the ON...
Right now my veg timer is set at 4:00am ON and 10:00pm OFF. I am ready to flower and my question is; would I harm the plants if I set the timer at 6:00 am ON and 6:00pm OFF? In other words, is it bad to raise the on time instead of just lowering the OFF time? Thanks to all that answer!
