I have yet to grow any tobacco plants whatsoever so u have a head start on me! If I am able to get my hands on the seed starter mix i want and the fertilizer i found through hours of research, im sure growing won't be an issue as long as mother nature doesnt scorn me! Lol We are known to get some pesky hurricanes and what not. You know, the usual Florida summer! Haha!
Just noticed your location, being that you are kinda down the road from me (I'm NW of Orlando). I lived in liveoak for a while, too so I'll toss out a few suggestions as I've found that growing tobacco here vs elsewhere is very very different.
Don't sweat the seeding, trays and LEDs, that's the easiest part. Getting 400 plants started for a $100 is a no brainer... It's the outdoors that are going to make it difficult and costly on you.
Send me your address and I'll send you more seed than you'll want to plant.
I have not been able to find a good starring mix for tobacco in the past 7-8 years in our area. Far too much peat / organics and WAY too chunky. What I do is buy 2 bags of branded potting mix, screen it with 1/4 hardware cloth and cut it 50/50 with course straight white sand. I would rather start tobacco in straight sand than high peat, I can compensate for nutrients but I can't overcome poor draining organics that kill roots.
We do double transplants, meaning I go from 70 cell trays inside to 4 inch pots outside on a "grow out" table. Reason being is a few fold. It's easier to start plants on trellises when they are taller than shorter but it also bypasses some of the pest and weather issues we have. I can easily plant in early February inside (back porch), move to a table outside and protect just the table from those screwy late March mid April frost fronts we get. You need to be very ahead of the early summer rains in spring and very past the tropical stuff in fall. Using pots and growing out seedlings to 12-14+ inches on a table make that easier.
Another reason I plant that way, pests!!! Everything we have friggen loves tobacco!!! The longer our plants are off of the ground the less pest issues we have to fight with.
Second to the weather, pests will be your number one problem so be very prepared to fight that with systemic monthy + weekly to biweekly spray application. What you can spend on pesticides in one season will pail in comparison to LED lights. The hawk moth horn worms are insane early summer (just at 90 degrees), the cooler fall season (now) is much MUCH more forgiving. You're a little more at risk for early frost than we are but spraying small plants in early fall is easier than spraying BIG plants in late spring/early summer.
Cutworms will kill anything under 8" in height and will kill several irreplaceable plants overnight.
Pesticide cost is why you've seen N Florida tobacco production fall out in the past 20-30 years.
You'll need trellises or will need to plant windblocks because of our screwy weather and fronts. If not your plants stand a good chance of being blown over several times. (Today's current cold front being a good example) A lotta rain and a few good gusts means half of everything would be flat on it's side in soft soils. Tobacco self corrects it's growing direction so fast that within 24 hours your plant will be 90 degrees in the other direction... You just can't fix it fast enough to save those prized lower leaves so prevention is the key. We do 12", 24" and 36 inch lines down our rows on tee posts at 15' spacing.
Use judicious row spacing (40'ish inches), you'll need the room to work.
Post spring harvest keep a close eye... We loose a LOT of leaf POST harvest to horn worms because the eggs and small worms come inside WITH the tobacco. (We air cure on the back porch, it's screened). Next spring I'm going to try treating with BT once, maybe twice (5 to 6 days in between) just before and just after hanging for cure. In fall you don't have to worry so much.
The plus side to our environment is air curing is so simple, hang it with fans, you're done.
We use drip irrigation, it's a long term investment for all of our crops but it really helps in getting water down in those dryer periods without constantly washing your pesticides off of your leaves and makes pumping out liquid fertilizer easy. We have no disease issues but grow in the wettest of climates. It also really helps on keeping weedseed at bay. IMHO Toro makes the best commercial nozzles.

The pictures on our grow table are from this morning, everything was just moved outside this week. Yes it's leggy, no I don't care, it outgrows it. Though, were a month + behind where I wanted to be (should have started seed the first of August). As you know our cooler temps came a bit sooner this year but with the number of plants we put in even if we get early frost we'll be ok volume wise for harvest.
For species, go with the more industrial varieties. Virginia grows really well here but the worms flock to it!!! We test planted Sobolchskii in spring and it did very well, was far less targeted by pests, cures easy, smokes well, handles flooding rain better. (Makes sense as it was developed in the Ukraine) I have some put aside to try out freebasing it for my dad's sinus habit.
With that knowledge our current crop is 210 Sobolchskii, 70 Virginia, 70 Rustica.
A few notes on Rustica, It's a novelty plaint but it's almost unkillable. It does well here but it's an easy target for pests. The army worms love the flowers and horn and other worms love the leaves. Most people grow this at least once "just because" and usually only once. We've kept it in our rotation as a "spice" to mix into our other leaf boosting nicotine. I like the peppery flavor it gives. I find the Virginia alone to be too bland for my taste but straight Rustica will make most people vomit because of the high nicotine.
Soil wise, get some tests done NOW and see what you need to do for spring. We have dairy goats and sheep that give is ample amendments but Floridas PH and loam means you usually need a lot of dolomite (lime) and potash... Tobacco LOVES ash!!! Putting those down Dec/Jan (even without tilling) for March April plantings wouldn't be a screwy idea. Lime takes time to do it's thing. Pre plant I till in 10-10-10 at 1/2lb of N + 100lbs of dolomite per 1000sf, we use liquid there after.
