For me the trick is to get them growing fast. It takes about 2 weeks for them to be able too. Use a good soil with apx 30% perlite. I used to use Happy Frog but now like Verdi-Fire I think the name is now.Do not be afraid to water them. After that second week once the soil is dry a little over a inch water again. I only use 1 and 2 gal smart pots. I start nutes at 2 weeks. 1/4 strength. I do organic so it takes a bit to get the ferts working. Keep pots warm dont let them get cold on a floor. I have three I started 2 weeks ago and are about 3-4 inches tall. If all goes good and you get them growing fast you can get good size plants. If I do it right I end up with 36-46 inch plants. I wont even mention yields because people do not believe me. My Royal Queen Auto AK-47s grow top colas bigger then 40 oz beer cans. I have had best results with HO T-5. Run a 8 tube on top and a 4 tube on each side. Always bubble your water. Keep PH in the 6-7 range. But like I said the main thing is to get them started fast. Do not believe the time to finish from breeder. I have only had one strain finish close to when they said it would. Keep them warm. I do the best with a low temp of 75 and a high temp in the 90 range. Do not follow the rule of waiting for leaves to fall off and then they are done. I have had autos go over 120 days and never loose a leaf. A lot to tell but in a lot of ways I like them. Show us how you do.
