Here's a quick info dump...
Pot size : for auto flowering strains it's important to start them in the pots they'll finish in. They should be 3-5 gallon pots max, anything more and your wasting space in your grow area. The roots will not likely be able to fill a pot more than 5 gallons in its lifetime. From my experiences I am confident in using 3 gallon/ 12 litre pots. These are you average size pots that you can find at any gardening shop. It's also important to drill many more holes for drainage, this is essential for all cannabis plants. It allows air into the soil/soiless mix aswell as give adequate drainage as to not overwater and drown your roots.
Lighting : for most growers a 24h lights on is not recommended. Even autoflower strains are in need of a rest period, this is when they stretch and develop their roots. Although some will swear that 24h is best, I have not observed this in my own experiences, Nor that of my protégés. I use 19/5 just to be different, since the consensus is 20/4 or 18/6 for auto grows. Full spectrum is always best, if your using cfls (which autos do great under) they should be of mixed spectrum. Using more cool white, 6500k, bulbs during veg and more sift white, 2700k, bulbs in flower. Usually a 2:1 ratio is good to have a good blend of light spectrum. Using LEDs is even better, and mh/hps even more so. Although with the mh/hps your not varying the spectrum like you could with the other methods. But results speak for themselves..
Nutrients : you will be using the same basic principles for autos as you would for photoperiods. The only difference is that you need to amend the schedule to reflect the growth you are witnessing. Autos have 5 phases of growth. Seedlings phase, this is when they're most vulnerable. Only minor nutrient solutions sound he applied if any. They've got enough internal energies to sustain themselves for their first week at least. Vegetation phase is next, this is when you'll be starting nutes like any other cannabis plant. Small doses at first and then ramping up to full feed schedule amounts in the weeks to come. This should be continued until pistils appear. At which point you may change over to bloom nutes right away to initiate flowering sooner or you can wait (like I do) until the Stretch is over and then commence your bloom nutes. Then it's full on flower phase, treat them just like a photoperiod plant and wait for the trichomes to start turning amber. Now that you've found some amber, we're in late flower and it's time to flush out all those nutes we've been putting in. Using a clearing solution will help eliminate those nutes from the media.
Training : I've had lots of experience with training autos, it starts early and goes until vertical growth has stopped. Most people will start with a o'natural grow to get their feet wet in this endeavour. It is recommended however, that you train them to increase potential yield. Topping is a great way to increase the amounts of Colas the plant will have. It's very important to know how your particular strain will handle the stresses inflicted on them. I like to top them at the 14-20 day mark. Giving you 2-4 weeks to train them depending on the strains attributes. Low stress training is probably the easiest way to increase yield. Just be sure to keep things levelled for the best results, evenly sized buds and a flat canopy to use the light most efficiently.
I'm sure I'll think of more stuff to add, but this a start to a thread for folks to learn all about autoflowering cannabis.
KiG everyone
