New Growth Yellows in my Hydro Hut?

[Berry_Coughin']

What I find VERY OVERWHELMING is the fact that there are numerous posts on the subject... from numerous 'seasoned' growers, as well as some new cats....

funny how most of the symptoms are almost frighteningly similar.....

Just check out the different people's pictures in this thread alone...

not saying we all couldn't be having the same deficiency... <--plausible...I don't rule it out...

I'd go out on a limb and say we are prolly not all running the same strains...same nutes... but what is a common denominator, is the tents.... just pretty odd, and a weird friggin' coincidence you have to admit.....

and if you fail to see that...then I chalk up your opinion as closed minded and bias, and if you take offense to that then I apologize....

But from what I've done in the past few weeks alone, has led me to believe beyond any doubt...that the tent...in some way shape or form.... whether it be ventilation issues... gassing off... for god only knows whatever reason... the tent seems to be the sole cause behind the problems I'm seeing...

I have a few satellite locations...and running a handful of strains....

I use both PbP hydro foods, as well as GH lucas formula....

I am under cfl....hps....MH....

no matter if I'm under HPS...CFL...MH in the hydrohut..... with either nutes...
plants of all varieties from f13-double sour diesel-blockhead-kksc-lemon thai-schrom-sweet tooth-c99 x grapefruit..... and a few others if you'd like me to sight them... they all yellow..... when they aren't in the tent... I don't see the same symptoms.....

Icky420 I see you're only 5 days deep into your tent....

Give it another week or two... I'll be here......

woohoo, im pulling up a chair to watch how your next 2 weeks go icky420. i dont have a hut thank god, but have been receiving plants that come from the huts. i believe it was taking around 10 days + for yellowing to show up. the plants that were looking a terrible yellow, looked perfectly green within 2 or 3 days from being out of the hut. for my buddy and i, its clear as day what the problem is............hopefully your luck is better than my friends

It is chilling that this is not figured out by us semi-scientists..... I returned after a long time, and still no resolvement. My HH sits in the box still...... Obviously, I have other things going on, but it is a shame about these huts. I believe my hut 4 X 8 fits in with the time when the problems ensued. But I may have got it before the defects became a problem.. The poles in my package are dull metal color, not white, not powdered.... Maybe I got lucky....? Any ideas...?

I grew in a 4 X 4 and a 4 X 8 before, and had no problems, it was while ago.

STILL, there could always have been off-gassing, just not enough to make 'em yellow..... If one can smell it, there are molecules floating around, right...?

We see recalls of products made in bad batches all the time, especially with products made in China, and other countries.... USA included...lol...

So, it should not be too much of a stretch to believe this 'Bad batch" thing occurred. A belief not necessarily based on the company;s actions after the fact, as that could be attributed to "Damage Control." It is a popular product..... ( they are making $ ).

No way am I gonna use mine without a test of the air within, and I cannot knowingly sell it to someone else, that ain;t right.

My friend just bought what he called a a new product from HH - sort of a squat closet type for moms, without any knowledge of this controversy/discrepancy.... He says he has had NO problems yet - 4 days in or so. It is new. We are keeping our eyes on the scene, 'fer sure.

Icky are you stubborn dude? seriously; the evidence is overwhelming and Berry has kind enough to explain it to you in so many different terms, what part do not you understand? All of it? Sounds like it......

I too have explained how this problem is occurring and why it is occuring in my posts in this thread. Berry has explained and given very good details and even showed before and after pics..... not to mention everyone else has had this problem and the only remedy was to remove them from the tent and they all got better
So are you telling me that all these growers don't know how to grow and ending up with the same deficiencies?

Let me tell you something icky, sulfur is a very rare deficiency in cannabis, yes it happens, but it's happend from LOCKOUT, not once have I seen a problem where there was a lack of sulfur in the plants diet. Cannabis uses such small amounts of it, that if something did go wrong it would show quickly.
So the only thing in common people have had these sulfur related problems is people who own hydro huts and have bought them in the last 6 or so months.

Oh, I also forgot to mention, Hydro hut themselves also said there was a problem with the huts, this is coming from the company and was even sending replacements and replacement poles...

so what more evidence do you need man??

 

[icky420]

Please excuse my ignorance:

Besides looking at your pictures, which I would never entirely rely on looking at pictures to solve a problem, I dont SEE a Sulfur deff similar to whats explained in many other descriptions. In your discription of S deff you state "Unlike a magnesium deficiency where it starts from the leaves tip and around, sulfur starts from the back of the leaves on forward to the middle of the leaves". Others explain it very much like N deff starting around the bottom which would also imply the yellowing goes from Tip in with intervienal chlorosis. Berry's pix look like the Veins are yellow, not inbetween...

Again this is all IMO...I think outside the box, I feel its my job.

stitch: you hit the nail right on the head and icky still doesnt seem to grasp what you're saying........even the company has stated that there are problems with the huts! what else needs to be said??

icky: if you look on any of berry's pictures...I only see yellowing at the top part of the plants. if it were a N def. wouldnt they be yellowing on the bottoms first like you mentioned in the post above this??? thats not the case though, so we can rule out thats its a N def.

I'm really glad i noticed this thread, as i was thinking of getting a HH to store mother plants in, but with all these problems with "off gassing" and them not being able to figure out if it's the poles or material the tents are made out of, i think i'll pass on the HH, funny how the first few runs had no problems, maybe they switched who they source their vinyl from??

Peace

I have had the same problem exactly as described.

2 huts, 3 houses, 3 media, 2 nutrients

I thought I was crazy until I saw this thread.

Everything I say gets misconstrued...Good Luck with your huts....

 

[Guest]

Well I cleansed my Hut and set it back up... I put one plant in it and not only is that plant starting to yellow, the ones I have in the same room (inside a closet) are showing symptoms... took about 3-4 days... typical. Bad karma for me, but I got to get rid of these things.

SOME LIGHT FINALLY!!!!!

My buddy at my satellite location took down the hut...

He was blowing my phone up all day today... I finally called him back 'WHAT!?!?'

" dude... I took the tent down... they are all greening up...overnight it happened.."

I knew this would happen...no surprise to me... but for all you doubters.... I'm going to go over there now and snap some photos....

I have no idea what I'll find, or what anything looks like...but my buddy has been stressing out, over seeing shit die in this tent for months now, he feels sooooo bad about it all... blaming his self in part..because everything I bring over there is damn near stellar in health... and a matter of days later it goes to shit... so I feel for the guy... not his fault, but he can't help but get on himself for these plants dying....

We lost an entire harvest of f13 and double sour diesel to the hut... thanks HH....

So.... without further ado.... I shall return with yet more pics of plants that have been in the hut...and the only change has been removal of the hut... we'll see what they look like now....

Oh...and in case you're wondering...yes I do have photos of these plants when they were in the hut...

So here's my new theory about this hut issue, and some documentation to go along with it..

I saw this post from another site regarding the vinyl..

After reading this thread, I have the same speculation as most do about the vinyl. I have worked with polymers for 8 years now and have some knowledge of vinyls. The vinyl could have came from a lot of mat'l that was poor grade or recycled mat'l. THAT vinyl is more than likely giving off small amounts of chlorine gas. Chlorine is BAD for any plant that i know of.

What, I wondered, would the effects of chlorine in the environment be on our little green friends?

I did some research and found some information I'd like to share.

From the book Reviews of Environmental Contamination and Toxicology By George W. Ware:
link

Interesting..

Also, from allexperts site:
link

What are the effects of chlorine on plant growth?

..many plants that are kept near indoor swimming pools, where the water is heavily chlorinated, suffer leaf discoloration and damage.

And from some Clemson PDF:
link1
link2

What are the effects of Chlorine on plants?
Chlorine is classed as a general biocide. That means that it will kill all life if applied in sufficient concentration. Sufficient concentration is the key phrase. Both concentration and length of exposure are important in the degree of damage caused by chlorine. In other words, even exposure to a low concentration of chlorine for a long period of time can cause severe toxic effects. Likewise, exposure to high concentrations of chlorine for even short periods of time can cause severe toxic effects.

---

The leaves are the most sensitive tissue and readily absorb the gas. The buds, twigs, and roots can also absorb the gas, but to a lesser extent than the leaves.

Seems like a possibility, a strong one in my opinion, so I thought I would throw this theory/info out there.

Now it's time to go research a bong hit...

Mr. Bongjangles... mucho K+ for the write up... much reading to do now.... thanks

Hi all, I have read 90% of this post and wanted to say I have been having problems with my plants since a few days after putting them in the hyrohut. Seedlings yellowed as did older vegging plants. I have grown before and could not figure out what the problem was. My crop has suffered for months.

I eventually abandoned the hut after building an 8x8 room but have still been having huge problems in my flower room, and now think that this may be the cause because..... I am still using the metal poles from the hydrohut frame in the flower room to hold the lights and fan!!!

I will post a couple pics of the plants at 48 days flowering, they are PATHETIC... the buds are decent but ALL the leaves are yellowed and dying and have been since a few days after getting the hydro hut. I have tried everything and my ph and nute levels have been perfect, etc. Even the new leaves that come out are instantly yellowing. Somehow, half the plants have managed to survive. I have 1 healthy plant right now and it is growing OUTSIDE of the flower room in another section away from the hydrohut metal frame.

I will be pulling the frame tonight after having read this thread and see if there are any improvements. Thanks to everyone for your hard work putting this info together.

edit: I added an image to my gallery badhut.jpg to show what my leaves look like. This is the pattern that happens to any plant going inside the room with the metal poles.

I emailed IGS this morning, and received the following reply.

I emailed IGS this morning, and received the following reply.

(I have had all the previously described problems)

The problem is sporadic. We don't have a way to fix the problem yet. We are working on that right now. It doesn't effect all plants and it doesn't effect all Huts. Due to this, please return your Hut to where you purchased it. I sincerely apologize for the problems that you've had and I wish I had a better answer to give to you. Because I do not have a better answer, I'm asking you to return your Hut.


The store will be credited by the wholesaler and I will credit the wholesaler. I'm very sorry about this issue.

Very nice write up bo!! mucho K!!!!

Yes, this is why it's only affecting certain plant species and not all plants, just like how some plants are more sensitive to sodium than others.
So if we could only find out how much PPM's is in that tent, if anyone knows someone from a lab or has lab equipment; you could easily get a reading from inside the tent and the air quality in there and BAM you will find out REAL quick what is causing this problem.

illperception, sorry to hear about your ordeal, but at least you have it figured out by now. man, im sure glad that i used 2x4's, plywood, and sheetrock! I just hate it when people buy faulty products and the customers are the ones that have to deal with the BS.
