LED and BUD QUALITY

[smirnoff420]

I wonder if one can make them move by themselves somehow? Maybe hanging them from strings from the ceiling in such a way that their own airflow will make them turn?

Like these things you put into childrens rooms, but with fans.

Fwiw since I started removing the grills from my oscillating fans I'm getting years from them with a little maintenance.

My most recent oscillating will be 2 yrs in Dec and my other I've had long enough to forget how old it is.

Removing the grill increases the airflow quite a bit and more importantly it eases the load on the shity plastic gears.

My fan runs 24hrs I think that might help the electrical side of things as it's not heating and cooling twice daily.

Whilst we've gone a little off topic and mainly because I'm trying solve my mold problem, since I can't do much to get my humidity where it should be consistently on my current space.
Does anyone know of an air purifier that cleans surfaces, not ozone based i know the technology exists that basically breaks down water into H202 vapour, I just can't find a suitable product that won't break the bank. photohydroionization is one of those technologies.
Apparently safe for humans, animals and plants.
Atleast with one of these running throughout my grow there will never be an mold spores present to grow despite the conditions

No it doesn't work like that. You will always have mold spores.

Even pharmaceutical standards of sterility say that there are less than 1 colony forming units per 100.000 units produced. Achieving that requires effort way beyong any cannabis operation. You can't even test for sterility.

the habitat recruits. mold spores are always there. they only become a problem when they land on suitable habitat.

you must control the environmental conditions that create suitable habitat before you grow.

you can scrub the space clean, use h202 between grows, and the instant you bring in fresh air the spores will be present again.

one of the best old school control methods is to spray your plants twice weekly with neem oil. during veg only, spraying during flower will taint the flowers.

what this does is impart a systemic resistance that will continue past the cessation of spraying.

but really, the best approach is to control the environment first.

Not even that. Porous surfaces such as plastic can't be fully cleaned. Sterilizing works to an extent (if the device can tolerate it) but some spores only germinate after a heat treatment so there's that.

Yea I fully understand that it's a habitat problem. The spores are always there settling on the flowers and only in he right conditions will that take hold.
However I know there are devices that go into ACs that will sterilise the air flowing through them . I found this product but im looking for a less commercial version

Good point, I will try using a dehumidifier sooner on the next run as well as some better house keeping in my room. Considering I've had humidity like this, a jungle and stupidly turned half the fans off/lowest setting my issue isn't too bad . Hopefully I can make it until finish time in a few weeks..
I switched at end of August and you can clearly see where I added the 315CMH and an Aircon a few days ago.

Scf, id try a bunch of small low watts dc fans, i droves in between the pots or directed to the walls. You need under cannopy air movement, but since height restrictions wont allow you to lolipop a few oscillating fans (our solution ) wont work. So next best bet would be to move the air below in a sorta "diffused" way: get air moving while not flailing against leaves.

Could be tricky to setup if youre on water collecting trays wall to wall (fan sitting in runoff water unless you figure out something clever) and then when you think you have a good setup with plants in place you get a lighter (or maybe a candle or zippo lighter) and try to find youre dead air spots, where the flame is not flickering. Eliminate these dead air apots and go growing.

If you think about it a little : wheres the largest amount of water in your growspace? Sitting in pots. I learnt the hard way never to water my mint plants late in the evening or at night. Powdered mildew every time due to rh being really high around a wet pot in the cold. If i watered in the morning with a day of sun on the plants never a problem. And of course time your watering to start of light on.

This the thread where led growers help eachother like bros but i agree its time to get back to led bud quality (im also guilty of derailing lol)

Yea at that humidity you get mold. Not much you can do about that but reduce humidty. If you have 80+ % in the 'open' then you have 90+ % inside the buds, where it truly matters.

That Airros device won't prevent that either. Entering the room will release millions of spores.

Pretty standard filtration will remove spores from the air. It's getting all the air done, that needs some thought. We can't usually have positive pressure on our spaces, so need to blanket them with clean air, so we know their is no dirty air to get.

It could get noisy, but we are not talking hepa grades to get the job done. It doesn't need to cost the earth

 

[greyfader]

powdery mildew spores are 1-3 microns in diameter so would need a fine filter to eliminate.

 

[JKD]

It should be remembered that no filters are 100% efficient. They’ll reduce the burden significantly, but don’t necessarily remove it completely.

 

[Ca++]

We see here that the white stuff wrapped around our filters, is general mould standard. However filter depth is a big issue. With just a 50% capture rate, you want a couple of tries, or a thick bed. Once we know that air is clean, we can think about hepa filters. We don't want to waste the costly hepa, catching spores that cheap stuff can be used for.

There is only so much you can do. I can say your covid jab or inhaler could of been develped at a site where I changed the filters. The only use of kit beyond air filters, was actually on the exhaust. UV, to deal with hazardous vapour in cabinets. Yes, I'm trained to put on a suit, to walk along like I have shit myself, to a room where I changed into another suit, to continue on my way. It was very clean.

The key here, is not to rely on any one method. Clean your room. Clean the air going in. Keep hitting the plants with things to get a protection response from them. Grow them with silicone to toughen the cells against attack, and remove all dead stuff before it becomes a breeding site. Open up the plants structure, and get air moving though them. Choose fast strains, and resistant one's. Don't dwell on the idea of if they need a bit longer. If you are not sure, then they are already done. Another week is just increasing the moulds chances.

Low voltage fans are a good idea, where things can get wet. Often an upturned plant pot can form a platform, or they can be hooked onto the side of containers, where they are less likely to get knocked over. Case fans like the 14cm ones, are only 25mm thick. They take very little space.

I super agree; do an everything approach, also remember that your led strips are fully sealed at 2 level: strips are coated themselves but also the diodes have a silicone protecting seal at manufacture: we occasionally burn sulfur, which can damage the diode (i think its mainly the little reflector that sits behind the epis and phospohor, which is made of silver. Silver doesnt like sulfur, just like youre not supposed to eat eggs with the nice silver); while weve not had any immediate break downs of any lights i know some of our older china boards have lost a fair bit of output. Those GLA strips should even be waterproof, you can litterally hose them down as long as you seal the solder join for the wires. Im fully comfortable burning sulfur with these while the rest is well buy new ones when they fail.

Yea sir! I will be posting some pics of my bud quality at week 7/8 shortly, some are ahead of others and looking so fine! Very dense compared to previous HPS grows.
LEDs are an absolute game changer with height restrictions.

What kinda of thing are you using as power supplies for these, in assuming you mean like PC/computer fans yea .

 

[smirnoff420]

I use ones like these, with a voltage dial 5v-12v to adjust fan speed.
