How many watts do I need for my indoor

I actually built a diy strip build. Similar to qb lighting. Its very intense and only costs like $1 a watt to build. I have around 400w of it but have only used 200. Look up hlg lighting. Its kinda expensive. But if ur gonna spend. Spend it right. No use buying something ur gonna get fluffy buds with. And if its just waaay to high, u can start small. Or do a build like me.
