This light is good for 2 plants but you’ll eventually want to add a second for your tent. You definitely can’t fill the tent with just this light, but it’ll get you started.

These are great nutrients and basically foolproof. This free sample kit will get you through 4 plants full grows. I love these nutrients and even now use them in a reservoir (which people claim you can’t do but works great).

That will get you started on your first grow or two. I recommend auto blue mystic from nirvana for your first run. They are very low smell while growing so you can get by without a carbon filter. They’re autos so you can leave the light on 24/7, and they finish fast. Also turns out a great finished product.

Less than $40 for 5 seeds and very discrete shipping.

When you have a bit more $ you can add on additional items. Eventually you’ll want to upgrade to PFD sun boards or quantum boards, but you’ll probably want to get a fan and filter first:

Activated Charcoal Carbon Filter 6" x 16", Up to 400 CFM, Premium Grow Tent Odor Scrubber, 1.8" Extra Thick Layer of Top Grade Activated Australian Virgin Charcoal-Great for Hydroponics and Growing https://www.amazon.com/dp/B01M0VN4I5/ref=cm_sw_r_cp_api_i_qN13BbEH9AG9W

Maybe you can upgrade to a 2x4 tray with reservoir so you can automate feeding.

If you don’t want autoflowers you can just do 12/12 from seed for faster harvest. https://www.royalqueenseeds.com/blog-how-to-grow-cannabis-from-seed-under-12-12-lighting-n330

But I really recommend doing the auto blue mystic for your first round or two.

If you're concerned about it, might as well test yourself. See this video: https://nutritionfacts.org/video/testing-your-diet-with-pee-purple-cabbage/

You could also use a cheap pH meter like this: https://www.amazon.com/gp/product/B00PU0W35K/ref=ox_sc_act_title_3?ie=UTF8&psc=1&smid=A2KV19AYUKS3X0

If you're worried about metabolic acidosis, just eat more vegetables: http://nutritionfacts.org/video/increasing-protein-intake-age-65/

If you want to take it a step further, you could install a RO water system, like this one with 6 stages. The 6th stage is an alkaline remineralization filter, and you could buy more of the alkaline filters and daisy chain them until you get to your desired alkaline pH level (using the aforementioned pH meter).

Cheap and easy. Get 2, you will thank me later.
