HydroHut HELP plants are about to die.

[dM2]

Hello fellow growers!

I posted this in the grow room thread but no one helped me.

Ok, I have a medical grow in CA, Growing 2 OG kush clones

Here is the set up:

Room: HydroHut Kindergarden Inside a 3 car garage.
Lights: 400w mh and 2 bulb t5 Fluorescents
Ventilation: [Intake: 6" 100 cfm Pc fan] - [Exhaust: 265 cfm 4" blower]
Air Management: 8" fan & Room humidifier
Grow Medium: Fox Farm 50/50 mix of Ocean forest/Light Warrior Soil
Nutrients/Supplements: Grow Big (6-4-4) / Big Bloom (0.01-0.3-0.7) / Tiger Bloom (2-8-4) / Open Sesame / Beastie Bloomz / Cha Ching
Termperatures: 75 to 84 Humidity 40/67%


The Kindergarden is for cloning/vegetative growing. I'm in vegetative growth right now with the light at 24/0 [24hr on/ 0hr off]. under the 400w MH.
The plants are about 2 months old and ready for cloning, but not looking the best for cloning. I dont want to clone unheathy plants and have them die. I have not had the time to be 100% in this grow so my plants have seen better days... BUT its time to stop buy and start growing...

How do i run the ventilation right?
The 100cfm Pc fan is the intake to the tent, pulling in fresh air in from outside the garage and the 265cfm blow is pushing the old air out of the tent and into the garage.

Now heres the deal. I turned the speed controller for the Exhaust blower UP to the middle [half way]. & Put the intake 100cmf PC fan to full blast.

OK the hydro hut I'm growing in is only 55' x 27'x 6'6"

now to find out the cfm in need in the hydro hut,

4.5 x 2.5 foot room with a height of 6.6 foot:
4.5 x 2.5 x 6.6 = 74.25 cubic feet of air inside the growing area.

Ventilation fans are rated in the number of cubic feet of air they can move per minute = cfm

Divide the air volume of the growing area by the number of minutes required to get one full air change:
If the room is 74.25 cubic feet, divide by 5 minutes (one air change every 5 minutes)
15.05 cfm

Is this the right way of have the best fresh air for the plants


Powdery Mildew?
I need to know how to take care of the powdery mildew on the plants in the tent.
I was thinking of getting a [Sulpher Vaporizer]
Now is this going to be to much for the small tents?
How do i add co2 with the Sulpher vaporizer?
If i cant have a electronic CO2 monitor in the same room as the sulpher vaporizer can i have the co2 monitor outside the tent on the power wall?


So, What am i doing wrong? plants are still dieing off slowy. Not over water, not over nuts,

the new leafs look pal yellow almost white, but the old big fan leafs look dark green. HELP PLZ!

Ill try to get some pics up later on this week.

Hey man there is a thread out here with a dozen people saying their plants are mysteriously having trouble in a hydro hut. Your environment sounds fine so your hut might be the problem.

[AugustWest]

dude i had the same problem with a hydrohut.. try a little experiment and take one of your stunted plants out of the hut and throw it in a closet under a CFL for a week and watch all the new growth.
from what i read (and i read a shitload about this) is that certain batches of huts were produced with lead in the posts.
once i got rid of my smaller hut my plants thrived.

this is a thread i started when my plants were dying in my hut of death.

good luck.

pulled this quote from another site:

Open Letter from HydroHut to the public

In the last several months, HydroHut has been made aware of and pursued a problem with some of its Huts causing a peculiar plant yellowing leading to plant whitening in certain, sensitive plants. While the issue did not arise in all plants, or all Huts, the existence of a problem was not conducive to our product's mission.

After several months of extensive testing, false positives and much interaction with the public regarding this matter, we have found an EPA approved compound that isn't stable in our plastic and that causes extreme stress to certain sensitive plants. In the future, this compound will be removed during manufacture.

Our focus has been directed at how to remove this compound from the plastic and to do so in a way that we could retroactively repair any HydroHut already in the field. As of February 2008, HydroHut will be repairing any affected HydroHuts at its facility. The exact process by which we repair the HydroHuts is extensive and proprietary and it will be carried out by a trained staff at our locations.

We fully understand that this situation with our product has adversely affected many clients. For this reason, we are standing behind our product and are offering anyone who has been affected a way to have his/her HydroHut repaired free of charge.

Any client, be they end user or store, can arrange to have his HydroHut shipped back to our Los Angeles facility for processing, free of charge. The HydroHut will then be shipped back to the client free of charge.

All inquiries for HydroHut processing should be directed to hydrohuts@gmail.com with no exceptions.

Please provide the following details in the email:

1) Size/model of affected HydroHut

2) Number of affected HydroHuts (only the HydroHut brand will be accepted for processing)

3) Address where the HydroHut can be picked up by UPS call tag (make sure someone is there to meet the UPS driver) Do not use a PO box as UPS will not pick up from a PO box

4) A name to whom/which we can address the package going back to you, the client. (We will make a good faith attempt at getting your product back to you. If nobody is at the address to accept the package three times, the package will be sent back to Los Angeles. Any further attempts to get the package to the client will be paid for by client.)

5) Please remove your HydroHut canvas or skin and box it up. Do not pack up your poles or hardware. Do not remove your frame. Do not attempt to ship us your frame or other items. We will only be call tagging the canvas in a box. You must provide that box and properly seal that box. We will send you a call tag for a specific weight based on the email you send to us with your HydroHut details. Again, we will only be taking back your canvas for processing; no other parts or hardware will be accepted. Leave your frame set up and intact.

6) We will make every effort to process and reship your HydroHut canvas within two weeks. This is not a guarantee but it is our goal. Please note that ground shipments across the USA can take up to 8 days! Even if we process your HydroHut in only one day, there could still be 16 days of ground shipping, 8 days coming to us and 8 days going back. Be patient. Most clients will not have to wait two weeks. Every attempt will be made to expedite each HydroHut.

7) If a store has new HydroHut, still in its original box, the canvas can be re-boxed in a separate box, and the canvas will be returned to the store new and folded, ready to put back into the original box. Please keep your original box at your store including all poles, hardware, and instructions. Do not send us the entire unit.

While this entire exercise may be time consuming, HydroHut is doing all that it can to rectify this problem as quickly as possible. We apologize to everyone for the difficulties incurred with our product, end-users and stores. Without a loyal standing of clients we would be nothing. It is our goal make this situation as right as we can. Thank you to everyone who has stuck with us through this difficult period.

Great info August. Do you, by chance, have a link of some sort to the original letter? I know of people on a couple of different forums who would be very interested.

There is a lot of info about the HH toxicity problem on IC Mag.

i don't man.. i grabbed that off of ICMag as CaliCoast said there's a good amount of info on this over there.
I had 2 tents the larger if the 2 works great for me and have flowered successfully in it a few times so far. The smaller one would kill anything i put in there whether it was established mj, seedlings or houseplants lol.

[Help_Needed]

Yeah, I saw that disaster disguised as a thread on ICMag lol. That's part of why I was hoping there was another source. There's so much vitrol and BS about hydrohuts on that forums it's hard to know which posts to believe lol.

Unfortunately there doesn't appear to be anything actually posted anywhere on HH's website. I might look and see if there's anything on the parent company's site.

[CaliCoast]

My HH is fine, haven't noticed any ill effects. However my thinking is some of those people are blaming the HH instead of their growing skills and knowledge.

maybe so.. but it's pretty hard not to get weed out of the seedling stage whether you have good growing skills or not.
when i take a plant out of the tent and it thrives.. then put that same plant back in the tent and it stops growing i'll continue to blame the tent and not my growing skills.

I bought this Hydrohut Mini two weeks ago. Since then, I have had nothing but problems from my little sprouts. I was sprouting under a 2x2' Floro lamp and moved into the Hydrohut with a 400 MH kept 18/6 and flooding my 3'x'3' ebb and flo twice a day, bottom 1/2 inch of pots are lined with clay pellets under the 4" rockwool cubes...Sprouts are Blue Sonja and Mr. Nice and were growing like gangbusters until about 3 days into the Hydrohut. Using Ionic Grow formula at 30% solution. Temps between 70-80 degrees and Humidity at 30-50%. I changed solution, backed off the light and kept ph around 6-6.5. I have seen some more growth, but all the leaves are yellow/green. I have pulled the Hydrohut canvas/plastic back off the metal frame and folded it up. Hopefully, the plants will begin to recover if the hydrohut is causing the problem...tomorrow I will line the metal frame with panda plastic and see what happens.

[SmknVTEC]

First problem is in rockwool pH should be between 5.2-5.8.

[xelatoth]

Ok, this is what I believe it looks like.

I put these in my new hydrohut 5 days ago green!!!

Now they look like this!

I have them in an organic seed-starting soil with 0 nutes in it and have been watering as needed with a light feeding every 2nd or 3rd watering at onyl about 200ppm or so.

They WERE green and now are not..lol. I took 1 out 2 yesterday morning and put under a small cfl in my closet and already is starting to recede in yellowness.

Friggin HH

I need to decide wether to get a homebox or a darkroom now, but the darkrooms are impossible to find in stock!

[AugustWest]

that stinks dude.. i'm sorry to hear It took me 3 months to finally figure out my problem... i can't tell you how many brands of soil and bottld water i used.. and how many seeds i wasted lol.
i have a 52 x 52 hydrohut for flower and it's worked great. I guess it's certain models or something.
best of luck man.

[MyFirstBud]

hey do u think that effects the 4x4 model, cause im having the similar problem with my plants, check the pic, its bad.
