Harvest a Pound Every Three Weeks!

[thinkhigh]

Also, your water temps need to be under 72 degrees. This is a common problem with all hydro systems. That's why you see so many water chillers on the market.

My veg room is kept at around 75 and the water temp is under 65. My flower room is kept at 85 and my water temp stays 68-72

StinkBud, I'm a noob and I've been reading you thread. Fantastic thread btw. Only up to page 53 and WOW what I have learned. I will be switching to your setup soon.

Right now I am running a eight line drip system for my veg. room. With 3-4' florencenses. Small res. with 5 gals of H2O,with foxfarm nutes (Grow Big and Big Bloom), and 196 gph pump. And a Ebb n Flo for my flowering room, with 600 HPS light. 18 gal. res. with 15 gals. of H2O and FF (Tiger Bloom) also with a 196 gph pump.

It's not even summer yet and my room is 79-80 right now with a water temp of above 75. They are not in the home but are in a building that is insulated but has no AC. I have a 4" inline duct fan pulling fresh air in from outside and a centrifical 6" inline fan pulling air from outside through my light and out the ceiling.

I'm sure it is as important for my water temp to be down in my type of system as in yours. What would you suggest? Will I have serious problems come summer time?

Definately subscribed and 1 up rep.

DIRTHAWKER,
What size is your room? Those buds do look pretty damn good.

Im running 4 600s with 3 systems. Its awesome!
But i wouldnt know the difference beacuse being this is new to me, i just went with what Stink said he would do if he could start over.
hope it helps with your decision.

CO2 in my neck of the woods runs $45 for a 20lb swap!
I heard fire extinguisher places can refill CO2 tanks?

Yes they can! Much cheaper. My wife works for a place that does it but when I start using it I am going to have to buy from a competitor to keep it away from her work. So much for a discount I guess!
I would check into it.
Your stuff is looking great as usual.

hey stink
when flushing w/sweet do i fush one day with it and then 2 weeks w/plain water
and do i start flushing when the trichomes are ready ?
thanks for any help

Thanks! I will definitely check into it. More options the better

I wish my buds looked as good as yours!

BTW I'm not harvesting near as much as everybody else--only average 4-6oz every two weeks. Also--I've never had 100% clone success... but 80% is good enough for me!

Yea this is a riddle i would love to figure out.

A few days ago i set my co2 to pump at 5 cfh... just to use up the co2 i had left in the tank. remember its been set at just under 2 for the last month. Well guess what its still not empty! Maybe i got lucky and found the only neverending co2 tank in the world...lol


I just dont get it!!

what happends to your guys tank when it is empty? and can you have too much co2 in the room?

i keep trippin in the twilight zone.
In disbelief i unhook the regulator and open the valve and sure enough... its blowin loud.

maybe i really did get a never ending tank?

Thy only thing that happens to my tank when it is empty is the CO2 controller keeps trying to compensate, and keeps the electronic valve open on the CO2 regulator. It gets hot, but I don't think it's worrysome.

I guess I don't understand where you got the 30 psi from? My regulator didn't have any instructions on setting the regulator pressure other than the CFH setting.. there is no way to do it on mine...

Mine just has the one gauge for the tank pressure, which starts at 900 for a new tank and goes down from there. This one has been going about a week.

edit: yes you can have too much CO2 in your room! Not only is it bad for your plants, it's bad for you too! The plants metabolism is saturated at ~1500ppm probably even 1200, there is no need to go over that. I've opened the tank and let it blast and watched the CO2 controller climb to 5000 in less than a minute... then it started blinking. Obviously not too safe!

Welp I can't find the actual article, but rest assured it was journal material
"...too much [over 1500ppm] CO2 will ... stunt plants but this is usually accompanied by chlorosis or necrosis of the foliage."
has happened to greenhouses heated with decaying compost, which provided way too much CO2...

 

[valmeida]

I only recommend a 20gal tanks system. It cost about $17 to fill and lasts 2 weeks. Anything else is not worth your time.

Roots don't take in CO2, they take in Oxygen. The leaves take in the CO2 through their stomata.

You can run the CO2 tubing to a fan or you can also buy hose made just for distributing CO2. It's thin neoprene tubing with a bunch of little holes. That's what I use. I run the hose up high around the perimeter of the room.

Stink,
I have searched everywhere for the already made CO2 distribution hose but i cannot find it. Do you hava a link? also,
couldn't I buy a hose adapter from 1/4" hose barb to 1/2" pvc and just make a frame out of 1/2" pvc and drill a bunch of holes in it?

HMM MY TANK DIDNT HAVE A GUAGE,, I bought this and hooked it to the tank http://www.hydroponics.net/i/131050 the directions said to set the guage on the regulator to 30 psi and tighten down.

maybe im doing something wrong?

the funny thing is , the buds are bigger somehow!!!!!

I don't think you are doing anything wrong....

Your regulator is nicer than mine, being able to adjust the pressure that the regulator is exposed to is better than exposing it to the actual tank pressure.

The only downside is you have no idea how much CO2 is left in your tank without the tank gauge.... You could weigh it though and calculate how much is left--if you had weighed it in the first place.

It's quite the mystery dude! I'm interested to see what is up.

 

[DIRTHAWKER]

The only thing that it could be is maybe the regulator is not calibrated right. Maybe when i had it set at 1.7 for the last month it wasnt letting out 1.7...maybe it was just barely letting out a tiny bit....

now that i have it set to 5..maybe it will empty soon and this episode will be over?


Its the TWILIGHT ZONE!!! Im tempted to just take the tank outside and open it up until its empty!! and start over.

I should send the regulator back where i bought it and ask for a new one.

If we assume you don't have a magic tank and your timer is working properly, isn't the only other option that gas isn't being released at the rate the regulator says?

 

[repvip]

How heavy does the tank fill? You should definitely notice a difference if its almost out...

I think you are right on though... Maybe it wasn't letting out enough...

we could do some quick math..

how long was it on for? 15 mins? every 3 hours? So... 1 hour per day it was on.

Now.. at 1.7CFH and only 1 hour.. you are only releasing 1.7CF per day.

Each lb of CO2 is equal to 8.7 cubic feet. 20lb tank->174 cubic feet.

174/1.7 is... 102 days!

Your room is 8'x8'x8' equal to 512 cubic feet.. now multiply that by 1300 ppm (0.0013) to get 0.66CFH of CO2 required to bring your room up to 1300ppm. You would want to release 0.66CFH every 3 hours for a total of 2.64 cubic feet per day...this is the same as a setting of 2.8CFH for 15mins on to get .66CFH. This would cut the time down to 174/2.64 down to 66 days... which still seems like a very long time!

Well.. the math backs up what you are seeing. Guess we will have to wait for the co2 controller! I am as confused as ever. My shit doesn't last long at all!

edit: these would be considered bare minimum requirements. Who really knows how much CO2 your plants are using.. if you replenished 0.66cubic feet of CO2 (to bring your room up to 1500ppm) every 2 hours it would last 44 days, if you did it every hour it would last 21 days.

I would place a bet that it runs out 2 weeks after you set the CFH to 5! Any takers???

 

[DIRTHAWKER]

Thats exactly where i got confused..the co2 calculator said something like 103 hrs at 1.7 cfh which would explain why its still pumping..but everybody ive talked too said that it should only last a week maybe 2...so WTF!! lol

but then again why are my leaves browning and drying up....

anyhow i dont wanna clog up the thread with my problems..i will figure this out.

thanks guys for helping out.

Another update and some questions.... =)

Hey, things are still going well. 19 out of the 20 clones have roots showing, some an inch in length or so.

Well, some of the leaves on the clones are starting to yellow (not dry/dead yellow). I understand this is from using up some of the stored energy in the leaves to go towards root development. I am still giving them straight ph adjusted water (170ppm, 5.8-6.0ph)

This batch was a trial mainly, since I have been so unsuccessful in the past. I tried different lengths, cutting the leaves in half on some (on some of the larger leaves), smaller, bigger, hard stem, soft stem, etc. They all (besides the one, prob will follow shortly) have rooted and in about the same time. I didn't do any cutting under water or dipping in solution, etc. Just a simple 45deg cut and placed in the cloner. Seems to be simple and it works.


The questions:

1. I am using the general hydroponic 3 part flora (not nova) nutes (veg, micro, bloom). It says for veg give (3-2-1 ratio), early flowering (2-2-2 ratio) and flowering (1-2-3 ratio). Is this a good guideline to follow?

2. Should I add some nutes for the yellowing leaves? Is this normal? I have heard of people adding nutes/foliar feeding to get rid of yellowing/stress from clones?

3. When I start to add nutes to the clones, what mix (ratio) or what parts should i give? I was thinking just adding micro alone for the first couple weeks, then going to the normal 3-2-1 mix. Suggestions?

 

[mafio]

im out of money and this all i have left


here my number

advan nute micro 5-0-1
advan nute grow 2-1-6
pure blend pro 3-2-4
seaweed 0.1-1- 0
liq karma 1-1-5


wat should i use two day of 12/12

 

[capman]

has anyone in here ever ran Snow Cap before? I am just finishing up week six and wondering if i should start my flush this week or wait another week then start it. I am starting to see some red hairs but still mostly white. Havent checked the trichs yet but i guess i need to. Also has anyone ever heard of Dirty Harry? My next batch is half Dirty Harry and half Blueberry.

 

[mattykyp]

Woohooooo!!! I moved my clones into the flowering box 2 days ago and they are starting to go mental now!!! Its great!!! they look so healthy!
Thanks stink!

thanks guys for helping out.

that is exact and if you ran 30 min cycles 4 times a day that is going to last you 51 days. My setup runs 4 cfh @ 15min cycles 3 times a day and it will last me about 60 days. If you aren't exhausting all of it out then you should be fine and it should last. But the only real way to know is to buy the $20 syringe that stink was talking about and the $5 rae test sticks and actually take measurements. Follow the directions and they will let you know if you are in the ball park. Should be @ about 1900ppm.

Now I just read mine tonight, about 1.5 hours after the cycle and the meter red about 800ppm so maybe the calculator is off and in real life we need double what it says.

I will post back on what I end up having to set my cycle to for my room, my whole room is about 10x10x7 with 10x7x7 of it filled with stinks systems, the rest of the room has tents for veg and clone.

Anyways Dirt get the syringe, it is about a $40 investment with extra test tubes and then you will know.

I think it would take some air flow numbers for the rooms exchange rate of air and a little more math to actually put that calculator into real time usage in our rooms.

BTW if you read back stink did mention that he used the syringe and test tubes to dial in his co2 before he bought his controller.
