new member, here's the setup, got a few Qs

Hey Included !

I miss overgrow too, but that isnt a reason to not overgrow again !

Sounds like hell your setup, but your space isnt very large as i can see.
Your Ventilation doesnt sound like overkill, you cant have enough ventilation when growing in a box. What you did miss to mention is your lightning power. How much watt is that bulb ?
Whats the temperature inside the box, and do u run your ventilation system allways on 100 % ?

About the CO2:
My CO2 systenm is incoming (growing in a box too), and i am wondering about the same question. The heat build up is large when you're using a total of 1000W in a box of 2m2. And my Outtake Vent is way to big to run it when injecting CO2 (~300 cfm).
Guess we have to find out self because there arent much information about this since overgrow went down.
On the other side i think its maybe overkill to use CO2 in a such small are like yours...

On the plants: They are looking good, hope u have fun !

Day 27 of flowering.

The smell is getting STRONG. Good thing I'm scripted, and my neighbors are cool as hell.

These are the happiest plants I've ever grown indoors. I wish I could get some shots of the roots up... but I'd need two extra arms to do that.

It's weird.... this is day 27 of flowering... but it's only day 34 in total.

These things were 1.5" clones 34 days ago. I love hydroponics.

Not bad bro. I can't wait to see how mine are going to look when they reach their 4th week. I am only on week 1.

I can't believe the smell coming off of these plants.

This strain is not supposed to do this at all... the crystal coverage in insane, the smell is insane, and the buds are forming so dense it's stupid. They're not even half way done and I'm having to brace the branches to hold the weight.

I love this hydroponics stuff.

I can't wait until I have some more room to grow some real plants.

Wow! Very nice grow, man. You seem to be an expert on nutes and leaf feeding and it shows in your plants.

Hey included, how hard is it to maintain your water levels and such in the waterfarms? Im interested in getting a few myself. They are able to be chained together with a master rez right? I would probably do a 4 bucket system but want it to be as simple as possible.

Now that they're fully grown... I have to add about 2 liters a day to the tanks. I alternate, one day there's half strength nutes in the bottle, the next, pure water with PH adjuster added.

I completely change out the tanks and run clean water through the hydroton once a week.

I'm no expert, I'm just going by the book.

I'll have more pics up tomorrow.... the change is incredible.

I can take a crack at your CO² questions for you.

First I rounded up your grow area.

Grow room area: 36 cubic feet
Amount of CO2 required: 0.0432 cubic feet
On time: 2.59 minutes

At this flow rate: 1 CFH

If you are using a 20 pound CO2 bottle with a regulator, it will last 174.8 hours.

So at 1 CFH your regulator is on for about 3 min. This will bring the grow area well above the 1500-PPM and closer to 2000-ppm would be my guess. I rounded up the area remember?

The idea is to raise the level above 1500-ppm and hold it there for about 3-4 hours at a time. Then exhaust the room and exchange all the air and do it all over again until the lights go off.

Now holding it there is the trick because with out a PPM monitor you can't calculate leakage, plant uses ect. So you can only guess.

My best guess is run your timer for 3 min just before the top of each hour. Then every 4th hour you run an exhaust cycle for 8 mim at the end of the hour and give the room 2 min to pressure down before you start with the Co² all over again.

The whole time you are using Co² the lights are on and you have a fan moving the air in the cabinet around. The exhaust is off and the air intake is closed off also. You need to hold the level for as long as you can so try to keep it from leaking out.

Did that help or do you have other questions?

Thanks for the help there Zandor....

I haven't fired up the CO2 system in the cabinet yet... the temp would SOAR in that 3-4 hour period.

I'm moving soon though, and I have a whole ROOM to work with the next go-around... so the CO2 will be used then.

Here's some more pics, I'm REALLY happy with how things are going (even without the CO2).

My temp is stayng nice and constant at about 77 degrees now that summer is in full effect.

Nutes haven't changed since the last time I posted pics....

It's about time for me to go shopping for leaching additives... any recommendations?


This is day 37 of flowering, day 44 total (from clones).
