You can look up the germination (seed hatching) temperature for various vegetables online. Compare this temperature to your soil temperature (even your air temperature to get an idea) -- the germination temperature needs to be met and sustained for the seeds to germinate (in addition to water, soil and presence of light for some shallow planted seeds). Most likely you will still benefit from starting indoors -- it all depends on temperatures AND which veggies you are planting - some veggies seeds have fairly low germination temps - beans, chard, mustard etc. Other veggies have very high germination temps: tomatoes, peppers etc. Remember that the germination temp needs to not only be met, it needs to be sustained. Since you can control your inside temperature - I would start my seeds indoors -- and potentially add a heating pad under the seedling tray. If you plant outdoors you can use a tarp to help warm the soil; I prefer clear elevated about 6" above the ground (like a green house) to help warm the soil when the sun hits it

Does it help to run a misting system during the heat of Florida summertime or would that do more harm than good; ie risk burning the leaves or inviting diseases etc.

my understanding is that keeping the leaves wet may make the plant more susceptible to disease and fungal issues, so its probably best to only water the base of the plant. Just make sure to give your tomatoes some shade throughout the day and i think they'll be alright

Did anyone else have problems with tomatoes this year I had to convert back to my tiny Toms ( skin too tough for those pesky pests next year I going back to Nicotine spray that'll knock them around a bit) .

I have a problem with wilt at the moment - never had it before. Very annoying.

I don't have much problems with cherry tomatoes - other varieties the pest generally get to them and yellow leaf curl virus. I'm going to try double layer of bird netting I bought cheap.

Hi I live in Central Otago and have a variety ot tomato plants that have flowers but no fruit. Am I wasting my time, will they produce fruit & ripen?

I find the shorter growing tomatoes like early girl do much better - anything longer than 8 weeks seems to only just have fruit at the end of the season and then no time to ripen

It says plant spring/summer, give them time to grow.
