Spraying plants in veg with water

[beasterblunts]

Hello all,
Longtime reader but first time poster, usually the search function keeps me from needing to post any questions. My question is in regards to spraying vegging plants with water. I have a partner in my operation and he relentlessly sprays our plants with water (multiple times a day, nearly completely soaking them each time) and although i dont feel its badly hurting them, I was under the impression that this slows down respiration from the leaves, which consequently slows down water and nutrient uptake by the roots. Am I wasting my time worrying? Or should I convince him to stop? He's somewhat stubborn, and I am too, but if I can show him some solid evidence of why it isn't a good idea, he would stop. So is it good, bad, or doesn't really matter? Oh and we both agree that spraying flowering plants with water is a no-no so no need to bring that up as an issue. Thanks in advance for any help!

I have a 1,000 watt MH in my veg room, and I have had issues with burnt spots on the leaves when I use any kind of foliar spray. I'm definitely not an expert on foliar applications, but from my personal experience I would definitely be worried, especially if he is spraying multiple times per day. The foliar spray that I used in the past was a once a week application. But like i said, that was discontinued due to leaf damage.

Thanks for the reply, I didnt think of the fact that the water droplets could reflect the light like a lens on the leaf and possibly burn them. Are there other reasons it may be harmful? Im using a 1k and 600w in a 4x8 tent currently. I haven't noticed burns but will stay attentive. Does anyone know if it does in fact slow water/nutrient uptake by the roots by slowing respiration on the leaves? thanks.

Yeah. There is no point in doing that only detrimental effects unless your RH is extremely dry or you need to apply a foliar feeding (only really needed if you have a deficiency to remedy)

Blasting water from the bottom can knock bugs off, but still...

You want your lights as close as possible without burnng the leaves, and as little water inbetween the bulbs and the leaves as possible for lights on

Your theory of uptake/respiration is true - closely monitor your nutrients and let the medium acquire some oxygen between feedings as well

Should be no need to spray them expect for special treatments, like say - neem, pyrethium, fungicide - etc

I think it is largely harmless and silly, but if your partner is going to do it make sure he is careful not to spray a hot bulb.

Edit: Get a bottle of neem oil and compromise with the dude. Tell him he can spray the neem 2x per week in veg and during the first 2 weeks of flowering. This will keep him happy and the mites away.

begs the question, why did you partner up with this jabrone?

Not sure if I would use the neem unless you had to. If its not broke dont try and fix it right?

It is best used as a preventative measure IMO and it does absolutely no harm diluted in a foliar spray; It is non-toxic to humans, degrades quickly, and doesn't hurt plants. I spray once a week minimum.

Edit: I see too many threads were people are considering using "no pest strips" and other harmful chemicals to control pest (especially mites) late in flower. All of this could be avoided by periodic neem spraying.

Fair enough.

it can also result in powdery mildew which sucks the big one

 

[AOD2012]

graham are you saying water does or the neem does? haha my bad kind of high and want to be sure...

[Graham Purwatt]

spraying too much water on your plants bro,i believe neem can help with it but not sure,never had to use it.

A little wiki research goes a long way.

Formulations made of neem oil also find wide usage as a bio-pesticide for organic farming, as it repels a wide variety of pests including the mealy bug, beet armyworm, aphids, the cabbage worm, thrips, whiteflies, mites, fungus gnats, beetles, moth larvae, mushroom flies, leafminers, caterpillars, locust, nematodes and the Japanese beetle. Neem oil is not known to be harmful to mammals, birds, earthworms or some beneficial insects such as butterflies, honeybees and ladybugs. It can be used as a household pesticide for ant, bedbug, cockroach, housefly, sand fly, snail, termite and mosquitoes both as repellent and larvicide (Puri 1999). Neem oil also controls black spot, powdery mildew, anthracnose and rust (fungus).

Yup, twice a week is plenty spraying - and you might as well juice um with the good stuff

 

[HymroD]

I read that you should spray after 5:00 pm as well...

Your partner is a fool if he is doing that in the grow room..recipe for powedery mildew if it doesn't dry proper.

One noob to the next..

Same.

Diluted solution in veg every week or 10 days, it's an oil so it helps disperse excess water.The flip side is over use can clog stomata.
I've foliared in the past, but for a specific purpose.Unless your environment is very, very dry,it's unnecessary.


Peace,

Yeah, tell him to quit messin with the plants! Im with pinecone on this one, if youre going to spray, spray with neem. I do it 1-2 times a week, with the lights off, out of my tent, so I dont ruin my bulb. Any bottle will tell you not to spray under hid lights. As far as clogging stomata, I think that results from people with bug problems freaking out and going "Im going to neem the SHIT out of these bugs!", and then mixing way too much neem with the water. Ive never had problems mixing normal amounts and spraying regularly.
But back to the point, at the least its pointless, and the most he's going to mess something up.

Spray clones and seedlings 1 to 2 times a day, by the time they go into bloom, all should be good, environmentally. Spray at night or with lights out is asking for problems. Mold/budrot. And yes, do not spray them, if you must, in close proxcimity to any HID bulbs. Bang, zoom!

. Barrin devine intervention
U are gonna hav problem or 12. This sounds like greed is his reason.

Get a new partner! Better yet do it all yourself.. good Luck

 

[Petruchi]

I spray water only on clones and even then only the first three days,...
