The Ethos grow is going well so far. Had a bit of magnesium def but I think I have it dialed in and they are really starting to take off finally. Just watered this morning before this photo and they usually droop a bit after but they should be looking real good when I get home this evening. Probably this weekend I was going to do an update to that grow journal after I go in and do some more training and some much needed defoliation.
Hard to know a true IBL unless you know the breeder. There is so many seed options now days that most breeders move on from a strain. In all my grows and hunts for seeds I've only found one that I was sure of. The breeder spent years on the crosses and then IBL to the 7th generation before he was satisfied.
Make sure to keep your female pollen dry, make sure its dry before you store it. It tends to go sterilized pretty quick. I always seperate it in different containers so I'm not exposing the entire supply every time I pollinate.
