Don't mean to be cocky - but it all depends how much space under the lights you have and how much a "bunch" is. If you have two 4ft. fluorescent lamps with two bulbs each - that will hold four standard trays of seedlings. If you are potting them up to traditional 6 packs thats 48 cells per tray which is 192 plants. I use larger pots so can only fit 32 plants per tray, but there is enough room for them to grow quite a bit larger than what is typically purchased at the nurseries. As far as height goes, its only limited by how you hang your lights.

Erika, yes you can pinch them. I pinch almost all the annuals and give many of the perennials a haircut in early summer to make them shorter and bushier. Works well, but delays the blooms a little bit. I grow Salvia 'Lady in red' and 'Coral nymph', also Yvonnes every year, but boy do the slugs love these plants in my garden. I'm going to have to be more diligent about apply the Sluggo around these plants this year.

I missed the spring planting, but I just bought a 4-pack of Lady in Red salvias to try out. I was going to transplant a few of them into the garden, but I'm not so sure now. I moved one into a small pot(the only plant with active bloom spikes). Of course, after growing in a tiny little container in a greenhouse for a few months, it is a somewhat skinny root-bound plant. I loosened up the roots before filling in the pot with a good commercial soil. The problem I'm getting is the plant is struggling when it gets even a little of the hot summer sun(this was the case before transplant as well). I've been watering it regularly and the soil has remained moist. This morning the leaves and blooms were getting wilty after only one hour of direct sun. When I moved it to the shade and gave it a bit more water it quickly perked up. The last few hours I've put the flower in a mostly shaded area under a tree that just gets a few peeks of sun. I just went out to check and several blooms that looked healthy this morning had fallen out. Just touching or breathing on the blooms caused most of the others to fall out... although the leaves were fine. I certainly can't transplant the other three flowers into the sunny garden if they are just going to wilt and die. I'm going to add some miracle grow to the pot and transplant the other three flowers to a large pot. A couple questions: Should I expect my salvias to better tolerate the hot sun once the roots are able to grow out in the new pots? They are never going to be as healthy as they'd be if I started them with properly spaced seeds, but, considering they are supposed to be full to partial sun flowers, I'd like to be able to get them some sun. Also, are the blooms supposed to be so fragile? How long are individual blooms supposed to last before they fall out? Thanks.

Lady in red is fairly common at a lot of stores right about now,. I recently saw some black and blues in bloom at my local lowes store but didnt buy any since I already have them. By the way if you have a nice bed of annuals that you like and want to overwinter you might consider what I did. After maybe the first frost or two I cut all the plants down to 6inches or less and cover them with plastic sheeting[visqueen] or a tarp and use something like sheperds hooks or bags of mulch or rocks or whatever you have to hold down all edges of the plastic , it works. I have a lot of salvia guaranitica and agastache tutti frutti which survived using this method.
