Switching from growing outdoors in soil to indoors in Coco Coir. What should I know.?

I'm new here to the forum (1st post actually) I've been lurking in the shadows watching and reading here. While I've grown MJ for a little shy of 10 yrs now outside in central Massachusetts. I'd like to attempt an indoor grow and I'm leaning towards using Coco Coir. Growing in soil for so long has spoiled me, I don't usually have any nutrient issues I may run into a deficiency here or there in the N the P or K area but Coir has NOTHING in it (correct.?) This would mean I'd need to supply ALL the "food" from start to finish.? I guess what I'm asking is before I commit to Coir as my medium does anyone who has experience with it have a list of what they used or wouldn't use again.? I want to get a ballpark idea of what the nutrients are going to cost me before I make a decision on what medium to use.
Additionally, will my medium dictate what my light source will be. I'm guessing it won't but I'd like to get some first hand perspective instead of a few Google searches and assume I'm making the correct decision.
Thanks in advance for any and all help.

A great site to help with your decision. Coco college.

Many run soil indoor with great success.
If I were an experienced soil grower, I might try both. One you know, the other you learn as you grow.

Things to consider....
Size of grow?
Room/ tent with intake/exhaust venting?
Sealed room with AC?
Budget!
Temperature and humidity control is a must.

Thanks for the link. There's definitely more information there than the 6-7 other sites that popped up in the Google search.
I thought of attempting to use soil inside but I read something about Coco Coir not attracting pests the way soil can (I've no clue if there's truth to this). I also wanted to try something new and still have fun doing it and thought a medium not as forgiving as soil might be a better starting point than a full hydro grow. Plus a few girls to occupy my time during the upcoming winter would make it pass quicker hahaha.!
Thanks again for the link.

Coco indoors is amazing, did it for two years on the west coast, I too am from central mass, living back in mass, nice to see people doing there thing out here, you know what nutrients and strain your gonna run yet ?

Kinda skipped the last part of your original post, 6:30 my brain is still waking up, correct with the Coco, you need to supply all the food, but unlike soil it's very easy to adjust, definitely get a ppm pH meter and test your run off, you can use cal/mag as a reset button of sorts and easily adjust your level s to where they need to be, some nutrients suggest food every other day and just cal mag with maybe something else light mixed in on the other days, but if done right you can feed every other day and have great results, I would run 6 days of nutrients and a compost tea around 600ppm on the 7th day to bring level s back down, as far as nutrients, the line I used suggested 5-7 nutrients daily, but if you read the label and adjust accordingly you can cut down to 3-4 , I ran minimum variety but high levels week 3-6 off bloom, week 7 ide run em high like 2500-3000ppm , it was glue and loved it, glue also doesn't like 1000 watt lights, had much better results on 750, then flushed week 8 back down to 100-200 ppm before harvest, don't be afraid to experiment with Coco, it's very forgiving, hope you got at least something out of this lol
