Im not a child, a moron or someone who hasnt done their homework. I purchased ALL this equipment before constructing my closet and long before I germ'd my seed. TDS Meter, Digital PH meter, PH calibration liquids, all my nutes, syringes for measuring, gllons of distilled water, ph up and down and so on.
Nobody reads posts I guess because I said I ph'd the the water I soaked my RW in for 24 hours. I also adjusted the ph in the soak 2 other times because it rose and made sure the run off was at about 5.5 before I put my germ'd seed into the cube.
The only thing I didnt have was that chart lol but I am more prepared then most newbie growers I see on the forums I frequent
Don't get so defensive . You admit this is your first grow . No matter how much you "study" it all comes down to actual experience . The people here for the most part are very experienced and knowledgeable . Sometimes questions are asked a few times . Just take a breath and give an answer .
Personally , I would have started with more than a single seed . It is always possible to get a dud . And my brief experience with LED leads me to believe it's better to start plants under floro for a short period of time then use the LED , rather than bang straight away with the LED.
