Thanks for this thread
@Buddy73 -- although I've been growing for years, this is the first time I'll run autos indoors through to a harvest (I did one aborted seed run so far). I'm keeping this thread open and I'm roughly following along with your training methods. I'm on page 3 right now, only day 12 for the oldest of my three sprouts.
There are some substantial differences between our grows: I'm going with three 5 gallon pots, and they are filled with a soil-based mix with simple time-release dry nutes. I'm growing under my DIY COB lighting, and I have a humidity deficiency. It's happening in a 2x4 "box" I threw together, luckily with autos "light leaks" are not an issue.
I'm obviously not as committed a grower as you are, I'm kind of lazy about it. It shows, already my plants are not as healthy as yours (at the same age). Because of that, I'm holding the lighting back at 18/6 until they establish, then I may add an hour until I get up to 20/4. Three 5 gallon pots would normally be pretty crowded for a 2x4, but I'm betting (or being naive) that the simple soil/nute combo, low humidity, and less than 24/0 lighting combined with aggressive training, will hold them back enough that they'll be OK in the end.
I will be interested to see how my 'low tech' lazy approach compares in the end to your really well thought out and beautifully maintained grow. It will no doubt help me to get a better understanding of the price of my prioritizing low effort above ultimate output.
