Light questions for grow tent

I'm planing fancy grow in grow tent, but I have few important questions about light.

1) I will use grow tent (dimensions: 47,3"L x 47,3"W x 78,8"H) with double bubble mylar inside, 100% lightproof for flowering/blooming. Would this box be too large for 250W HPS light (3500lumens)? Or I have to drop grow tent size to 39,4"L x 39,4"W x 78,8"H for 250W HPS? Max plant count in tent - 10

2) Which is better light for bigger yield and buds - 250W HPS-TS or 250W Quad Band LED (9400Lm; 3500 - 6500Lm)?

3) For mother, clones and growing from seed till I can put under HPS light for flowering, found "NeOn-KIT Megalux 11.000 lumens - 110W" light (2 x 55W; tube length 23,6"; tube width 9,8") Will this light be OK for max 10 plants?

Thank you for your help!

1. 250 isn't enough, a 400 should do nice...
2. LED is still rather new technology for growing, and is controversial, not to mention the cost for an LED
3. maybe for seedelings and first week of veg, but after that, it wouldnt be able to support ten plants

That SLB for advice!

The smaller tent shoud work and add a few cfls. you should use some nutes to (i use foxfarm tiger bloom) i pull 4 oz easily without nutes but this is my first time wit the nutesand im shooting for a half p. just bought a 600 too though so i would say get the big one if you get a bigger light (600 is the most efficient)otherwise the 250 is fine jus keep the canopy even and the light close
(3" is where mine is maybe closer

no prob mari!
