First Diary - White Widow & GD Purple

I transplanted from red cups to 1 gallon fabric containers this week. Added Great White on roots of each. Roots were nice healthy white when I could see them and clearly wasn't root bound or having any issues. Added small auto-drip system to each of the 6 plants this week. Testing it out allowing it to run ph 6.4 water for 1 minute every two days, mainly so I can go on vacation in April for a week. Lights are currently at only 16 inches but running at 75% with ppfd around 400-425. These lights are pretty weak so being that close is hopefully ok, plants seem ok with it so far. When they were in red cups I could use one light, now with 1 gallon pots I've turned on my second light in my 2x4 tent. Temperature has gone from 72-74 with exhaust fan on lower setting to 75-78 during the day with exhaust on a higher setting. Warmer air and more flow is good.
