From seed under 400w duel spectrum

Right this is the idea I have in my head and ill stick it in order. Can someone tell me if this will be ok? Still new to this you see.

Buy feminized seeds (not sure what yet)

Germinate (paper towel method best?)

Stick under a 400w grolux duel spectrum from seed at distance (my undertsanding is they can grow from seed under the sun which is billions of times more powerfull, so why not a 400w as long as the temp is ok?)

What do I feed this seed, and when do I start feeding it? (ive used Vita Link products in my first grow but that was a clone, not a seed)


I stand to be corrected on all of this but in theory would this be ok?

Also considering autoflower due to time, any recomendations?

I've never had success with putting them under a 400watter sooner than 8 days and even then I work them in slowly. Anyway they will soon tell you if it is too early when the leaves fold up.

It's easier to start under fluresecent bulbs for at least a week. 400 is really strong. Also outside plants have the room to grow really tall where as you probably want short and bushy
