Is it ok to move plants outside at 3-4 inches. What month can you start plants outside in Indiana? What is the best terrain/place to plant them.

I dont know what the weather is like in Indiana So I cant tell you the best month to put them out. It would be best to put them out when there is no more frost. Frost is a killer. The temp at night should'nt go below17 or 20c but I have had a plant that was covered and the temp droped below 7c and the plant survived about a week of these low temps. Until the weather improved maybe I was just lucky. Some strains can go lower without dying. if you do put them out and the temp drops cover them with a sack or something over night and they should survive quite low temps and the sack will stop the frost from killing the plants.
You can introduce your plants to the sun in stadges. I dont I put them straight under the hot African sun no problem but if you do put them straight out just keep an eye on them to be safe.
Good luck.
