I grow Petite Havana SR-1, Wisconsin 38 and Burley 21. In addition to Nicotiana tabacum I grow Nicotina benthamiana.
Conditions in the greenhouse are probably a lot different than what a field grower is experiencing though.
/if you need me I'll be in my GH spraying for aphids, thrips, whiteflys, and every other pest insect you can imagine.
Gardening is mostly an issue of your enthusiasm holding up until you get used to the work.
