Again, here is what I have already started Well I have shasta daisies, columbine, delphiniums, black eyed susans and white cone flowers started.
I'll be doing some of my veggies this weekend (broccoli, cauliflower, egg plant) and then a few others in 2 weeks (peppers, tom). What is the best temperature in the greenhouse for these kinds of things?
I have 2 40 watt lights clipped under my trays (cheaper than buying one of those heating mats). I put my indoor/outdoor thermometer in there last night pretty on top of my tray. It read 75 degrees when I got up this morning.
My little set up tends to fluctuate from 68-75.

Your temperatures are good. Keeping it warm enough is not a problem for me since my greenhouse is heated, but keeping it cool certainly is once temps outside climb and the sun shines. Last spring not a problem!
Excess heat really does stress out plants.
Don't know what your set up is like , but keep mild air movement to prevent problems. For mine temps don't go below 60's, preferably 65at nite, but I raise some cold-sensitive flowers. Mid 70's day temp.
Of course if it's 85 or 90 put that's another story.
Sounds like you're doing well and having fun !
It's a learning experience

Check in seed catalogs/websites like Johnny's, Territorial, Stokes, etc. for appropriate germination temperatures for each kind of plant. Its a good idea to do this BEFORE sowing seeds because you don't want to group the wrong ones together in a same tray.
Cole crops germinate in 2-3 days at 72-75° but need to be transferred to suitably cooler growing temperatures after germinating. Some seeds won't sprout in soil temps below 50° or 60° and peppers and eggplants take forever to sprout unless you start with soil temp at least mid-upper 70's; yet others won't sprout when temperature is too high for them, etc.

The high temp can also be solved some by adding 50 gallon drums of water since they stay colder than the actual temp. A fan blowing o the drums when the temp gets too high works for over heat as well as extra heat in a unheated greenhouse. My greenhouse is not heated but maitains temp above 35 all winter! My heat chambet is heated some and stays above 40 even on the coldest days and my seedlings have come up fine so far.
