Hello All-
Here's a few things I've learned and do when it comes to growing huge outdoor plants.....
1) Going from indoors to outdoors, Put your plants on a 15-9 light schedule indoors. If you go from 24-0 or 18-6 schedule to outside you will run the risk of your plants going straight into flowering. You don't want that.
2) Plant on the waxing moon phase. I plant my outdoor garden on the waxing moon phase (May 4th through the 14th for me this year, I'm in central Ca). Farmers have been doing it for centuries, so I do it.
3) Prepare your site/garden area. I put fish scraps, horse manure, chicken manure, molasses, lime, forest humus, earthworm castings, and other goodies into the garden through out the winter/spring and till in as needed. You want to get your soil nice and alive with a micro-beastie herd before you plant. You want those bastards to be feeding, farting, crapping, and fornicating as much as possible.
4) Dig a big hole and line with half inch hardware cloth. You don't want any gophers/moles eating your plants roots. Fill hole with QUALITY SOIL. I use Foxfarms X Bio Bizz, and plant your girls in that.
5) I use raised beds with 2feet of half inch chicken wire around the plant, rabbits, rats, mice, squirrels, and other pests will eat your yummy plants.
6) Water heavy fewer times vs. watering just a bit a lot of times. Believe me this makes a huge difference.
7) Don't overfeed. I feed once every 3-4 watering, or when they ask for more food.
There is much more to growing outdoors, but these are some of my hints to growing big plants with large yields.
Good luck-
