Was about to reply on some of the questions on the first page when i noticed 17 pages and the first page being back from 2021 haha. I can see you got your light issues sorted
If it hasn't been mentioned on the pages in between the first and this (yeah, i didn't read it all, sorry!), there's this thing called PPFD. It stands for Photosynthetic Photon Flux Density, and is a measure of how many photons actually get to the plant at a certain height of the grow light, usually measured in micromoles (umol).
Grow lights are a fecking jungle, and many manufacturers/resellers don't state the PPFD of their products, either out of ignorance or poor performance i guess. Often you will instead get some indication of lumen (which is basically how bright it looks to us) and kelvin degrees, which is basically how cold or warm the light looks to us. In other words, you generally can't use those measurements for plants at all.
When they DO provide the PPFD, it is often an amount of umol at 10 cm height, which isn't bad, but that also means you have to worry about the spread and effectiveness/decline of said light at that distance to the plant.
Then you can go "BIG" and buy one of the many top brands grow light setups, but they have some issues too. Those issues are usually not with the light itself, but the cost of the gear, and the watts consumed.
I don't know about you, but i'm not made out of money. So in order to get decent results indoors, either just for sprouting, seedlings or the whole process, you really have to have a large look around on the market. What i've found so far is that low wattage fixtures with a PPFD of around 200-300 umol/s works pretty well if you have enough of them. In my personal setup i use 6 LED tubes at 12W each, with a PPFD of 240 umol/sec if i remember right. They are mounted on a frame of my own making, and since they use only 12W each, its a measly 72w for it all. Each LED tube i've bought for around 240 DKR (~35 USD) totalling 1440 DKR (210 USD) for my setup. You can easily find setups that will cost 5-15000 DKR (730-2200 USD) that promises to do the same. And sure they will do that, and probably a little better too. But they will cost you an arm and a leg, and will usually ride your electricity bill to the skies as well with 500-2000w.
Anyway, just a little post from me
If you had all this sorted on page 2-16, then just disregard it all haha.
