Advice? 3 part General Hydroplonics. What else?

So i have everything set up for my tiny babies in germination.
I'm growning 3 afghan ryder kush in a 15inch deep by 25inch long by 18 inch high
platic "tote"
Should i paint the clear tote, duct tape it, or just cover it in mylar?
Or all three?

Here's my main question. I'm running the DWC system. I bought the 3 part general hydroplonics nuets. What else chould i buy"? I want ALOT of wieght on this bud. Its just for me but i would like a small break from the room from time to time.

Seaweed stuff? Root enhancer? That damn store has so many options.

I use 3 part gh nutes with nothing else added and I get decent results,I plant to use some kool bloom this next grow. good plants come from good genitics so if you start with a good strain chances are you will end up with decent smoke,also you may not want to mix organic ferts with non organic ferts,and you will most likely have heat issues with that tote,use a cooler instead keep your res between 60 and 70 deg and you will be fine

I would definetly use the koolblooms. I would look into the cooler you need your res temps to stay down and that can be hard with a good light.

i would master the 3 part base nutes before trying to add anything to your mix, once you have mastered those then throw some kool bloom in the mix and you will actually see the difference opposed to just using it from day one and not knowing if its even doing anything, allot of great growers are not using any additives just a solid base formula and everything else dialed in.

Learn to grow, by which i mean physically grow, not watch a video and think you're set, then start worrying yourself about maximum yields. So many new growers seem to make it their mission to get ahead of their abilities and knowledge.

That seems to be the problem with a lot of beginners. They use 15 different nutes and additives, and are then puzzled by what went wrong, and have no idea what caused their problem, with no idea how to fix it. Just use the 3 for now. Get it down, then tinker.
