Purple plant 3-months old, 3-4 weeks into flowering.

I began with 9 plants underneath 4 four foot fluorescent tubes. Space became an issue so I gave 5 of them away. Three of the remaining four were males so I annihilated them about a month ago. This was about the same time that I purchased a 150 watt HPS security lamp. Luckily the plant that has survived is a Dank/headies/KB strain. (the buds are bright purple) She began to flower about 3-4 weeks ago. The temperature is around 60-70 degrees in my grow room due to the window unit air conditioner I "Installed" last week. I'm interested in putting a humidifier in the room, will this have a significant impact on the potency of my yield? Is it too late to do so? It has thrived well so far in it's current conditions which is why I am not very eager to change them. I am no expert however this is my first (successful) grow. I have no idea what the humidity percentage is but it is a closet grow with air intake from an attic-like space. From what I have read the air is probably drier than it should be. Any input?

excellent work man, she looks gorgeous.

stick with what works. "if it aint broke dont fix it"

I will keep it as is then, I'll post weekly pictures. It should not be too much longer until harvest. A few weeks or so.

she really looks nice, done well mate

Here is a picture update. Is she almost ready to harvest?

nice i wudnt wait any longer

Wow, those purple buds are looing pretty dense. Great work man, how much yield do you think your going to get?

I hope to get an ounce or more. I'm not going to harvest her until the white hairs stop reaching out and turn a darker color.

Sweet dude, about how tall was she when you started 12-12?
