Admittedly, I’ve been out of the indoor game for several years. I’ve been growing outdoors for the last decade + , and have had no need for indoor. But situations have changed and I set up a sealed cO2 room, 10x8 with 2k of air cooled DE HPS lights, Using 15 gallon air pots and 900 ppm CO2 for veg. Growing in SubCools SuperSoil. After starting 5 packs and sorting through the retarded seedlings, pulling males and herms as thy showed up, I was left with 10 plants to grow. As time went on, all Hermied or turned out to be male.
What is going on??? Am I doing something wrong??? I feel like it’s a conspiracy! I’ve been growing for 25 years and never had this problem.

49/50 is a ridiclously high herm and male rate. Possible the females stress hermd? What was the source of the genetics?

I had a pack of Caps Waiting Game which pretty much all hermetic. A pack of Archive Seeds Toyz which was a lot of them were retarded, LuckyDogSeed Co Chem Fuego and a pack of The Potion from Archive. And some others

I thought so too, the sealed room is perfect as far as I can tell. But the temps are 85 because I’m running the CO2. The growth was explosive fast

That happened to me once. I had an auto about 5 years ago that was 100% hermie. I planted it outdoor at 5 weeks and it flowered and pollinated itself right away. I tried it indoor a few more times before I flushed them. What a mess.

I question the interpretation of seedlings being “retarded”?
What does that even mean?
Unusual early formation or slow growth compared to males is no reason to cull
I never cull anything till I flip it
I think you tossed a bunch of girls based on male growth
Such a waste

I’m thinking you might be right. I picked 10 males out of a 50 sprout

If gassing in light and dark is all on you, fresh air for dark cycle. Propigate in basement highest co2 in house. Give co2 after plants start to grow but be careful bc roots need o2 when plant uptake co2, small fan blowing up from floor should help. How much co2 for seedlings? 400 ambient more than enough. In flower you pump up, big veg maybe 600 to 800ppm depending on size, retarded seedling were trying to compensate for co2 levels. Btw not trying to be dick. Just trying to help.
