Haha, that was me when I started. I wanted it "super ez".. A lot of people will say don't use MG potting soil (Miracle Grow), but I did for 2 years, and I only used 1 bottle of MG all purpose plant food... Now I use 'OLS" (Organic Living Soil) here's a link to a website for beginners... Living Soil: The Ultimate Beginner’s Guide | AgZaar ... It's fairly ez once you get in the habit.....And BTW, in soil I have never had to PH my water my soil does it for me, and I use regular tap water...and another thing you mentioned 4 or 5 plants in a 4x4 tent is way too many, start with 2 and believe me they "will" fill your tent when done. Good luck! ...lol...and another thing I forgot to mention is I can reuse my soil over and over again, now it's called "ROLS" recycled organic living soil...I'm hoping to use one soil I can buy in bag form. I really don't want to mix my own. I also want one fertilizer I could use start to finish. That's simple to me.
