Grow Mediums Considering DWC First Grow

[Tetra9]

I am considering doing DWC for my first grow. I'm just a little confused on a few things.

I picked up Dutch Passion's Colorado Cookies & Blackberry Kush. Along with an Electric Fruit Auto.

Grow space size is 63x24x58, would a 1000 watt HPS be too much for the space?

How often do I need to change the water/ nutrients & how would I calculate how much I need for 3 plants?

Will I need more than the Humbolt Farms A&B Nutrients?

I am open to all suggestions and will document my grow once I get everything set up.

Thanks!

Hey @Tetra9 bud hows it going?
Is that skunkwerks rx grow and bloom all in one? That sounds great wonder i can get it in ireland?

Hey Bro long time no see ! Yes, I'm pretty sure they ship anywhere in the World within reason. Here's the site ! They have a 2 part pro series that kicks ass for Auto's as well. You can really tweak it so there's less and less Nitrogen towards the end.

Those questions are kinda similar. Every grower has a different way of doing things. Some like to keep res changes to a minimum and it also depends on reservoir size.
The larger the res the less often changes are needed.
My advice for a first timer would be to res change every 7-10 days it gets you used to doing it.
So for the first 2-3 weeks the res will last through the week-10 days.
Then when they get bigger they start drinking a lot so you will need to give top ups between changes. Depending on res size
