I have decided to take my grow space to the next level and will be installing T5s this weekend to supplement my lighting. The grow space is in a south facing bay window with blinds but in the winter when it's cloudy and rainy for weeks on end I know the plants aren't getting enough light. Luckily for me my son works at a hydroponics store so I get the friends and family discount!
It will be interesting to see how much of a difference this makes in flowering.
