My 1st grow

This is my very first cannabis grow so I'll leave some basic info here: I've been planing this grow for quite some time now, reading on the internet, books, talking with friends, watching videos, etc. I should probably just go for a non-smelly auto indica in a soil, but that just sounded too boring to me. I opted for a photoperiod strain in DWC grow. With SCROG. Under DIY lamp. Yes, for my first build. Since I managed to pick not-so-basic techniques, at least I set my goals a bit lower than most. What are my goals for this growth I hear you ask? There is only one goal actually: to not kill this plant :) And if I manage to learn while not killing it, hurray for me. So first I started to build my light. It's a LED strip light using mid-power full spectrum LEDs (EB Gen2 strips), color temperature 4000k. This temperature was picked according to datasheet since it was the warmest color temperature that still has enough output in blue part of the spectrum. 560mm strips were used, 10 of them. Each of them runs at ~19.6V-ish, and their rated current is 7.5A. This works out to ~150W of power. At this parameters strips are quite cool, and could probably be run without any heatsinking. I used aluminum U profiles for fixture, so technically I am using heatsinks (kind of), but fixture is quite cool to touch. Even the diods themselves are not that hot to touch. Then I started to buy everything else: grow tent, exhaust fan, charcoal filter, duckting, buckets, netpots, hydroton, nutes, air pump and hoses, airstone (I'm using a small wooden one, since bigger stone ones gave me shitty bubbles), pH meter, EC meter, pH adjusting solutions, air temperature and humidity meter, etc. It ended up being quite exhaustive list with much more stuff than I planned for, but I got it all, built my tent and installed all the stuff. Everything runs cool, quiet and stealthy. Then I set 1 seed to germinate. "Just one?" I hear you ask. Yes, juts one. If it's of any quality, it will sprout. I have sprouted seeds before, just not cannabis seeds. Some pop fast, some that long time (2 weeks or even more), but they all either sprout or they start to grow mold. My seed sprouted, and I might say it sprouted quite fast and looked good doing it :) I left it on paper towel for 3 days. I should probably leave it there a day more, maybe even two days, so the root would get bigger and longer and thus more suited to transfer to hydroton. But this was my first grow, so I guess this was the first lesson learned without killing the plant. She took the transfer well, the root kept growing and soon some greenery appeared. All this was wihtout any nutes, under a "seedling light", which was just a 13W cool white LED E27 bulb fitted in a desktop lamp connected to mechanical timer set for gas lantern routine (12-5.5-1-5.5). Oh yeah, did I mention I was doing weird light timing for my first grow as well?
