I live in the middle of the country, haven't sprayed the leaves with anything and all I have left in the greenhouse are sativas. Also, the GH is only 4 months old with no signs of mold. Thanks for all the suggestions!
Does your GH have a floor or just the same dirt that was always there?

Or just put a hood so it blows down and spreads better?
If the intake is at ground level and shaded, and the exhaust is as close to the roof as possible, then you may not need a fan. This technique has been used for centuries. The sun heats the air and it escapes out the top and sucks cooler air in from below. I've seen quite a breeze in a GH setup like this with no fans.

Where did this come from? Why do you think fem seeds cause hermies?
Just experience and anecdotal agreement among professionals. And the opinions of certain articles. And the opinions shared by a friend who works in a cultivar lab. And all the fem seems I've ever bought. And the general accepted opinion the preference for regular seeds from bulk growers. The reason for the hermies is the lack of male genetics and a plants natural desire to corrects its DNA to procreate. When you're born from 2 mothers that are born from 2 mothers it just seems to happen. As those plants wouldn't exist in nature without man cross breeding fem seeds.

"I personally choose to discard any genetics that get bud rot. And I only get bud rot when I buy feminized seeds. And the plants grow huge buds. Clones are never an issue."

Disconnect on my end? I don't think fems necessarily lead to herms.. I was asking Ponky if Ethylene gas or colloidal silver solutions produce better fems that lead to less bud rot or if his experience is just anecdotal and he doesn't know how said seeds were femmed!

Not trying to hijack thread!

Cheers!

Ponky,

Any thoughts about why fem seeds seem to lead to bud rot? Methodology matter?

Cheers

I will look for the article I read that explained with scientific terms the names of plants bred with each other that are feminized or lab cultivated. I haven't read it in awhile. It was to do with landrace back breeding projects. I'm hoping someone knows what a plant bred from 2 mothers is called. Something opolid or something like that. I'm not that into botany but it explained a lot about seeds and the value of genetics.

I have not heard this. I'm surprised that I haven't, from your description I would think this would be a much larger topic.

Oh sorry I missed that part. The seeds I received that were poor quality fems I believe or Rhodenization seeds. As every crop dropped viable seeds. I currently have new fem seeds from a better lineage that are supposed to be bred differently. So they shouldn't drop seeds or be weak. So far they appear robust. Haven't been sexed yet.

Low quality seeds are from herm crops and I think the rest use gibberlic acid or colloidal silver. So source really matters. Not all fems are equal.

Low quality feminized seeds. It's a thing. It's where poo comes from. I mean I just smoked a Bruce banner from fems. And it's OK. But it's always gunna have tiny little seeds. Because I didn't get it from a good source.

This isn't exactly it.
Many of the seeds that we can find in shops are polyhybrids, crosses between different hybrids. The offspring of such crosses are in many cases quite unstable, (from this article)

There was a scholarly article about this with more precise wording. I can't find it yet.

I may not have heard of this because I was never that interested in the breeding aspect since we have just enough room to do our regular grow. So, I generally avoided those threads.
But I'm currently reading 'Evolution 2.0" by Perry Marshall. Very interesting book about genetics. It answers so many questions that I see broad overview applications for all plant life.

I was never into any of it until my buddies got those lab jobs. So I didn't know why my fem seeds sucked. And he basically told me it's because I'm a chump trying to buy seeds online from strangers. And they don't have the catalogue to back breed from.. then I was lost. Realized how blessed I am for the cuttings I can get. And began a journey to smoke good outdoor. And find new strains people like. And edibles that work. And the science part is tough. But becoming a bigger and bigger part of it. Feels weird to see it evolve the way it has.

Hello all!
I'm brand new to this site and to posting anything on one of these forums for that matter. Not really sure which forum is the best for growing but whatever... I've been using much of the Fox Farm line, from the trio (BB, GB, TB), to Open Sesame, Beastie Bloomz, and Cha Ching. I use it almost exactly as they recommend and have had great results! growing mostly sativas/hybrids with a few autos thrown in. I'm growing in a greenhouse and I'm now into week 3 of flower and just switched more than half of them from OS to BB, while steady on with the big 3... the only issues I've had is that they are all so big that some have hit the roof!! luckily I have the room to move them around and put a few outside. Not a bad problem to have. the majority of my crop are all feminized sativas/hybrids and they couldn't be better. My one issue is with the autos and this has happened now to every auto I've grown this year (8 autos, 4 already harvested), and that's that they've developed bud rot!!! I harvested the ones in the first crop due to BR a month ago and just today I cut off a number of buds on the second crop that had beginning signs of it... they are all tiny spots of rot but it kinda freaks me out. Did I get bad seeds? is it bad genetics? are autos generally better under lights? All the autos are outside now and set well apart from the rest as I don't want to infect the others. I thought the BR might be due to the humidity in the GH, but I've got 6 fans going 24/7 in there and the humidity is not bad. The sativas love it!!! any thoughts? I probably won't do autos in the GH ever again... that said at the beginning of August I put in the rest of my autos just to see if I could get a 4th crop this summer and that's the pic with all the babies...View attachment 1162129View attachment 1162131View attachment 1162132View attachment 1162133View attachment 1162134View attachment 1162135...
I have had same problem with auto grows here in upstate N.Y. I don't really mess with the autos any more , I generally just buy feminized. Just because I am such a rookie and can't tell if they are male or female. But my experience with autos hasn't been great either

I'm also in upstate NY and have decided either to have autos outside or not at all. I gotta say that I've learned a lot in these last few weeks. I've cut back on my watering now that the big ones are in full on flower and my humidity level has dropped to 50% or less. So in looking back on it I now think it was all my problem in not keeping the humidity down earlier and possibly overwatering. I think the autos need way less water than normal feminized plants and if I ever do autos again that's the plan...

Hello all!
This has nothing to do with your soil.
is it bad genetics?
Not necessarily "bad" but not good for your conditions.

Most folks on here are obsessed with creating optimal conditions instead of finding genetics that work with their imperfect ones.
You could buy equipment and spend money on power to run them and emit carbon to create the perfect conditions, or you could go with genetics that work with your climate/conditions and spend your resources finding genetics that work even better.

The problem is most breeders are doing all their selections under optimal conditions instead of breeding for greenhouse or outdoor conditions. This is basically the same race to the bottom that industrial ag is running.

Because most fem seeds are backcrosses. Literally inbreeding.

Backcrosses can preserve elite lines but they tend to be less vigorous and can lose important genetic traits like resistance to pests or diseases.

This is also why, despite having a greenhouse, my outside plants are chosen to finish before the end of September. It becomes too hard to control the environment in my greenhouse once we drift into October. There are plenty of fast/early finishing photos that will finish in a Michigan September. It's much better than dealing with but rot and other issues that pop up in the fall.
