thanks for the tip. any idea what kind of PPM a calcium nitrate foliar feed would be ideal for a 3 week old seedling?

I water 200ml to about 20% runoff. Weight right after runoff is about 290 grams. Weight when I usually water is about 170 grams. Right now, after almost 2 days it's at 200g. So it's going at the same pace of about 40ml a day, I suppose. I've read that watering just around the top portion could...

i've noticed my seedling has some slight yellowing along the bottom leaves. after ruling out nutrient burn i'm guessing that it's a nitrogen deficiency, as the other leaves have also taken a lettuce-like sheen to them. i'm in coco right now and watered about 40 hours ago. thus far, my schedule...

appreciate the tip. when your seedlings were overwatered, was it coco or soil? i did a pinch test and while it wasn't dripping, there did appear to be some particles of moisture. i'll put it under the air-conditioner's breeze... the room is hot anyways, the lil lady could use some cooling down.

right on. i'm hoping it's not even root. i see a sliver of green and it seems more girthy than other people's pictures of upside down seedlings, so hopefully the cotyledon will emerge. i didn't squeeze out the water from the coco after the initial watering, and just left it for about 4-5 days...

thanks for the reassurance. so you're saying this growth is root then? would sprinkling more coco on top would make it a bit more comfortable? i was worried when planting that it was too shallow (slightly less than half an inch) should i leave the light on and put the the seran wrap back on the...

howdy all first time growing, just had my 2nd sign of life, the seed seems to have broken ground. i noticed the seedling is somewhat yellow, and there is no presence of a seed shell to be found. is my seedling growing upside down? i planted about a 1/6" taproot facing up after seeing the...

indeed i did have some luck. it must be luck since no electrical understanding was involved on my part. i tried setting it up the way you described but 2 of the 8 sections weren't lighting up. the sections corresponded to the 2 connectors that weren't in use, so i figured they had to be...

thanks for the detailed explanation. i'll give it a shot after eating... if i start fiddling with it now, i'll end up starving myself for a couple hours trying to figure it out. basically, it goes? 1. L+- hooked up to R- to create the serial connection 2. L- hooked up to -driver 3. R+- hooked...

My apologies if this is the wrong place... but can anyone give me instructions on how to connect my non-official qb288x2 leds? When I first hooked it up, it was only drawing 125 watts. Apparently, it was wired up in parallel. I tried to get it wired in series but it hasn't worked. The best...
