Correct lighting? Help.

Will 2 x mars ts600 be enough to flower a tent 90cm x50cm x 160cm.

Yes, absolutely. Only real issue is gone be that you'll have to get those lights probably 10" from the plants which could cause a heat problem, even with weak LEDs.

Wow, diddnt realise they would need to be so close.What about as seedlings? currently have them at 22''

So, here are the PPFD maps of your light at different heights. Each square represents 5". For vegetative, you want 400-600. For Flowering, you want 500-900. Your seedlings will be happy with 200-400. The high end for each of these ranges is best, the low end would be your minimum for decent growth. It looks like 16-18" is your best bet for the seedlings depending on how you have them set up.

Thanks man, appreciate it .

Makes it super clear.

Would the light being next to each other and overlapping light double, or almost double par readings?

Logically, it makes sense to me, but I couldn't say for sure. Sorry.
