I was going to point you towards
@Doug Dawson 's thread.
Start to finish on a Mars Hydro kit.
My 4x4 veg tent has (2) Viparspectra burples running 530W total. (the grow link is in my sig)
My $.02:
READ --- A LOT.
Read all the grow journals you can find and copy the one you think that YOU CAN DO. There is more than enough info here for almost any grow method.
-- I thought I was going to do vertical aeroponics when I first thought about growing.
Then I read the learning curve, the headaches, the expense, the specialization ---- so I grow soil in a tent with LED -- pretty far from what I thought I'd do - but I grow unreal weed.
BELIEVE people when they tell you that Amazon light won't actually flower a 4x4 tent, and does not compare to a 15,000 watt double ended HPS while running at arctic temps.
-- I bought a kit with a light that would, "flower a 4x4". It doesn't. Now I have 6 similar little LED boxes - some with names some without. Some work great, some not so much. --- I would have saved a bit of money, and A LOT of headaches if I'd listened.
DON'T believe people who say that a "burple" (red / blue based light) won't work. Most of them work well --- if you have enough of them (see above).
DO - grow. When you can't get everything perfect (FEW, if any do) - Just grow.
Take all the advice you can get.
Build and grow as close to that advice as you can.
Improve each grow.
Again - figure out what you can build in your budget, follow advice, GROW.
