That 70's Grow

Have just been trying to keep enough light on them, being at the end of 5 weeks since light cycle change I just ordered a digital Microscope to check colors, no amber ones yet that I can see with a magnifying glass. This grow has tought me some extrmemly valuable information and learned how to overcome numerous issues. For example my 6" oscillating fan wehnt out this week, works for awhile, then makes a noise and gets how. I have taken it apart and tried to fix it, but it seems the motor is burning out. As long as the manufacture continues to stand behind them, I continue to contact them and if that fails this time, I have a $1.99 Square Trade 2 year extened warranty. These fans burn out quickly after 3 months of continued use. I keep 2 in my tent and this is the 3rd that has bit the dust. Only paid for 2, have been reimbursed for one and one was replaced at no charge.
