Hiya

I'm germinating a bunch of seeds at the moment, have one seedling.

How much is too much light for a seedlings thats pretty brand new? couple days old? 2" tall? i have one under 3 bendy blurples bout 4-6" away from the lights - the blurples are weak AF, 26watt but ones busted (used to one of those shitty 4 headed bendy ones but one broke and old goes red so just turn it off).

my plan was to have them under there until they're a bit older, then transfer to my micro grow box which has a total of a whopping 30watt (2 panels advertised as 100 and 50, really 20 and 10 lol) was thinking if they're too hot for them i could just have the smaller light on first.

then when nice and strong, put them under 220watts of cob, two of these - https://herbals.co.nz/collections/led-grow-lights/products/4seasons-luma400ledgrowlight

does this sound sensible? or too much? they're photos not autos.

PSA - first time grower. learning as i go. have a micro test grow in the micro box but pretty sure its male, will know for sure by the time the seedlings go in there. if its female ill make another box.

also have some bag seeds germinating. actually tbh i have a few too many germing hahah, only want to grow 3 females but have like 9 more germinating? guess more to be sure

Get a light meter and watch this paying attention to DLI

Bugbee is the only referral I make for YouTube. I mean he's literally a PhD and is head of the hemp research program at Utah State University. An expert on light spectrum and photosynthesis. More than that but for new users to LED (me last May) this guy is a must.
