Will a plant continue to flower even if it has light leaks ?

itsaliveterps · Jul 30, 2023

I bought a dehumidifier for the flowering phase just to make sure my humidity levels and temperature were safe anyways? to my horror the dehumidifier had green led lights on the dials etc I did lots of research about green light during dark phase conclusion was very mixed it's safe it's not safe anyway dehumidifier was all setup things were good life was good I was good the plants were good and in full gear flowering I got to the beginning of 7th week and there they were pollen sacs and even a few small nannies this can't be happening after all this time and everything but what's confusing to me? Is the 3 out of 4 plants seemed fine I noticed the one that hermied had that hermie characterisic weak smell compared to the other 3 so I pulled it so my point here is I think it hermied because of the green light on dehumidifier but will a plant still flower? If light leaks?

The short answer is yes, it will still flower. If the light leak is bad enough it will display hermaphroditic traits like nanners and even full on male parts. It's been debated a bunch about whether or not a small light like a power strip or humidifier can be enough to cause it but in my experience it's better to be safe then sorry. Use some black electric tape to block the light or several applications of black nail polish will dim it out as well. Certain genetics are more stable than others are have zero issues with it but others can go off the rails as soon as they don't get the full dark period in flower. Sorry to hear about the plants.

I doubt it was the green led light, plants go hermie all the time (too often, IMHO), sometimes it’s a stressor, often times it’s bad genetics.

Hey man ye it sucks big time all that effort and patience anyways I did try my best to cover up the green led light display with foil tape but to my horror it would still bleed through the plastic of the dehumidifier and even the fan part of the dehumidifier which emitted a slight green glow in the tent during dark phase I gave it my best shot to cover up with layers of foil tape unfortunately I still needed to be able to set the desired humidity levels on the led displays so I couldn't use black nail polish otherwise I would never be able to know what humidity levels they were on etc in the end I just pulled all 4 plants out and harvested which is a shame i suppose its possible bad genetics could be why she hermied I keep thinking what caused this to happen and there it was it was obvious the green glare from the dehumidifier in my opinion plants need 100% darkness even a little green light is not safe especially for long periods let alone 12 hours lol this was a learning experience I like to call this trial and error.

Hey man sorry I'm not really familiar with the term IMHO? and ye its a tricky one for me to answer because your right so many things could have stressed them out but I gave so much energy and tlc and tbh I did make a few minor mistakes but it still plays on my mind what could of caused my plant to hermie? So in my opinion plants need 100% darkness otherwise you risk hermie plants be safe not sorry even a tiny green glow which I thought was safe isn't 100% safe during dark for me this is what caused my plant to hermie.

Had this in my tent the whole first run......

It was bright enough so I could work in the dark when needed.

Never had a problem, but I've not had it in the tent since.

I do use a green flashlight when working in the dark now though. I still haven't had any problems.

Its green and its a tiny 3w led at max.think of it like this when a full moon comes does it fuck the plant up? No.

It WAS NOT the led that made your plants Herm. There is no chance that little led put off enough light to initiate photosynthesis and interrupt the plants night cycle. I’ve personally had all sorts of indicator lights on various gear over the years with any issue. I even started leaving my door partly open to my veg area for air flow which allowed a good amount of light to splash off the floor of the flower room. I could easily see in the flower room but none of the light was directly hitting and plants and the reflected radiance in the room never effected anything. I’ve also watched many many other growers with LEDs and equipment in their rooms never having issues.

Plants don’t need absolute darkness, they need it dark enough to stop photosynthesis. That is why the bright ass moon doesn’t interrupt their growth outside. That is why small LEDs in your room aren’t your issue.

Some genetics will herm you might not have done anything.

I think we could debate about this forever I'm just going to go with maybe it was maybe it wasn't but the reality is for the next time there will be no dehumidifier inside the tent with bright green led lights during flowering dark phase and hopefully just pure darkness so
hopefully i will see what happens next time and yes genetics could have contributed to hermie the possibilities are there but for anyone else reading this stay safe go pure darkness it's to risky for your plants I covered the LEDs with foil tape and it still bleeded through the dehumidifier its really upto you me personally I don't think its 100% safe to have any kind of light inside the tent with flowering plants period.

This is word right here!!

I don't even worry about working on my plants in flower during their sleep stage anymore. No I don't have a bright light shining in but a single ceiling bulb so I can see to work, and my tent is a cheap POS with a leaky zipper and I have most of the bottom air flaps open 24/7.

It's not an issue....no hermies at all. I have had hermies before, but always from the strain, and not in a long time . (knocks on wood)

Now what we all should worry about is damaging our eyes from bright lights!!

Dehumidifier should go outside the tent anyway...

But what if it gets too humid inside the tent? I don't have a way to exhaust fresh air from outside so my only friends are the extraction fan and circulation fans and keeping my door open in the room I'm growing in my cuz was saying the same thing that the dehumidifier would probably work better outside because its doing the whole room? But this confuses me because keep thinking inside the tent is where the humidity will be lol

Lol bro It's a highly debatable topic most plants hermie because of light leaks or some other kind of stress issues my seeds are from a very respectable supplier but it could have been a genetic thing who knows

The humidity is created by the plants in the tent, but your exhaust fan sends it out into the room immediately, and replaces it with fresh air, also from the room.

If the dehumidifier is outside the tent, it's dehumidifying the whole room, and your exhaust fan is pulling that (dehumidified) air into the tent, and exhausting more humid air, which the dehumidifier then dehumidifies, etc.

If your exhaust fan is working right and you're cycling the air into/out of the tent fast enough, there shouldn't be much difference between the humidity in the room and the humidity inside the tent.

I'm not actually sure how much of a difference it makes if you put the dehumidifier inside the tent vs outside, since it's technically dehumidifying the same volume of air (room + tent). But it's definitely easier to work with outside the tent, and if you have a drain or a sump nearby, then you can hook up a drain hose and not have to empty the tank periodically...

Thanks bro makes sense I'm definitely going to try this next time I was using a hose to drain the water from the dehumidifier it's a decent dehumidifier.

How do you explain that outdoor plants don't hermie under moonlight then....or under big outdoor night lights? I use to think the same thing, that TOTAL darkness was necessary, but that defies logic!! Stress and genetics cause hermies.

And yes, run the dehumidifier OUTSIDE of your tent, and if you don't have a drain nearby you can use a condensation pump. Mine runs 50' from condensate pump to a drain and it is so nice not having to ever empty buckets....Plus the thing can run 24/7 if it needs too.

Same here, I just turn on the ceiling light and don't spend much time there.

I was never debating with you, it’s not really a debatable topic, it’s science. I only posted on this thread to share plain facts with you. I have almost 20 years of indoor growing experience, including testing most of the broscience and old hippy logic in side by side situations.

You started the thread with a question and clearly a lack of experience. So unless you just wanted to hear people confirm the light leak idea I would recommend paying attention. Several other experienced growers have confirmed what I stated and if you research how plants actually work you find that it’s just botany. Those little LEDs or even basic light leaks aren’t producing enough energy to initiate photosynthesis.

Will a plant continue to flower even if it has light leaks ?
