Part grow In the sun and T5

After getting seeds to germinate,the first week seems to go great.(I tend to lose out in the second week stems getting very thin then just give up)
Can I put 7 day old seeds in sun starting from an hour then increasing as the second week progressors.

After spending time in the sun,
I can take back to T5 and complete 18 hours on.
This is a veranda grow using coco core perlite and 10 % potting soil.
Very light 1/2 mill in a litre of nutes after four days.I check weight of cup before watering.
I only have T5 lights available, so any tips would come in handy.
Happy growing all.

I grew a crop under T5s that were loaned to me. The growing tips could touch the bulbs without apparent damage. When those plants were larger, it was no problem moving them outside for a few hours, then back inside.

You have lost that one seedling, do you know why? The other one looks yellowish. It's of a size where giving it some limited sun would be okay, but I'd want it healthy before changing its environment. I can't help you with coco, though.

think it was to hot outside for little cup hence roots fried ?

You can probably keep the cup cooler by shading the cup itself. I'm not sure how long you've been growing, but coco is hydroponic and is more involved. Potting mix is better for newbies, it's more forgiving.

Inside, you're using T5 grow bulbs, yes? They come in a variety of colors just like CFLs. 6500K is good for vegetative. I never let the growing tips intentionally touch the bulb, as they grew and if they touched, I'd raise the light fixture an inch or two.

R.I.P. little seedling .The other seedling one on the left was repotted and is in full sun know.All good.
(thanks simple)
