Mars TSW2000 or T8 Reptisun for seedlings?

Good morning
Starting my first indoor grow. I have germinated my seeds and they have developed half inch tap roots. I have peat pucks and a dome to get them going. I have a 15" T8 reptisun tube light from my old bearded dragon or my Mars hydro tsw2000, 300watt LED, which is dimmable. The propaganda dome has a top which would put the T8 about 10 inches away. Is this too far away? That is the closest I can put that light. I have a portable heater which i can use to warm the room, if i go with the T8. Which light source would be better? Any help would be appreciated!!

Good morning: you don't need a dome for seedlings. The T8 should be fine to start then you can get the 300W light started, dimmed down to about 30%.

I love my TSW 2000 and have used it to flower several runs, and also used it in a 2x2 dimmed to start seeds and/or clones. I even started flower in the 2x2 with it, increasing the intensity.

Thanks!! How far should I place the T8 from peat pucks? Should i put into solo cup and put a baggy on top of cup, to retain a humid moist climate?

T8 and no dome

Domes are for clones

T 8 can be only a couple inches as long as you raise it as needed
No baggies or domes it causes issues

EDIT: Oh and WELCOME to RIU

One more question:
I have some mycro Jordan, should I add a tiny amount to top of peat pucks when going from wet paper towel into peat? Or should I wait till they go from peat pucks to soil?

Why not skip all that and start them in soil
Btw what soil?

That's what I thought when I walked into the local garden shop. Once there he swears by using this technique and said I would be pleased with the results. So I have ventured down this road, we will see how it works out. I will be using pro mix hp, and adding advanced nutrients micro,grow bloom. Also have green planet vitathrive(B Vitamin) and myco Jordan for root development. Had the 3 part nutrients given to me by a friend. Going down the more complex road to start. I have grown outdoors before and always went with more of an organic soil mix.

Ts-2000 just dim it down all the way and you’ll be fine at around 24“ above canopy…reptile bulbs emit uvb which will harm them over time and slow growth

Thanks for the shared knowledge everyone, appreciate!!!
