I've never grown hydroponically, so I won't be of much help there, but welcome to the growery!

You'll definitely want a controller for your co2, preferably one with fuzzy logic since you're running bottled co2.  As far as co2 levels go, I would set it between 400-700 ppm for veg up to week 3 of flower, then increase it to ~1250 ppm over 2 days from weeks 4-7, then bring it back down to around 650 from week 8  to finish.  I'd also vent at night to keep co2 levels from climbing too high.

Actually, to be honest, I wouldn't use co2 for your first grow.  That's more for when you have everything else dialed in (nutrients, lighting, VPD).

Before I actually post some water testing results, I had a few questions:


1. Is there a cheap way to automate water pH?


2. I have an LED light, do I need a water chiller, is it overkill since I have hydroguard (beneficial bacteria)? Does anyone use Hydroguard? How much should I use? Does the amount go up over time?


3. When you use pH storage solution, do you put it in the cap of the pH meter and then put the cap on and store it upright?


4. Is it better to start in Rockwool cubes and then put the cubes in the net pots with the hydroton, or is it better to start the seed in the hydroton?


5. When do you take a clone? If the growing cycle is 12 weeks, do you do it on week 8? I want to minimize smell. How long until they start to get smelly? Just to reiterate, I have never grown this stuff before.


6. I set up my duct fan. From what I gather, the fan big flexible tube should have air blowing out of it and the carbon filter should be sucking in air, correct? Or am I going to have to pull that shit down? I looked at pictures online of this duct fan. There is an arrow on it, if that helps. 


7. I have never used a smart plug in my life. If I plug a smart plug into a power supply will it still work?



8. I have those two 6 in fans in there. They are pretty dinky. Will they work for this grow, or is there a better thing that I should use?



9. That pump vibrates so loud!!! is there a way to quiet it down? Is it just loud because I haven't used it, inside of the 5 gal buckets with the stones on, in water? Or am I fucked in those regards? I searched for quiet pump, and couldn't find a technique posted here for quieting it.


10. Am I going in the right direction? Any other advice you can give me? Thank you again for all the help!




Finally, I realized that I should probably post this in the grow log forums, sorry jannies... You can move the thread if you like, but I like that it is in the main cultivation board. I love you.

Okay, so on to my nutrient regimen. I had to post a second update. 

I understand that from a lot of YouBoob watching that a nutrient regimen is slightly based off of what they recommend and also some other things.

I found a <img src="

video called "The Captain's General Hydroponics Nutrient Recipe that matches my nutes.

HOWEVER...

If you look at the General Hydroponics chart (Drain to Waste) it says for the Week 1 Seedling stage:

Flora Micro 2ml/gal
Flora Grow 1ml/gal
Flora Bloom 1ml/gal
Diamond Nectar (don't have this)
FloraBlend (don't have this)

But that seems pretty strong. I mean, I am not running a giant system. This is in a small 5 gallon bucket I am thinking that I will do about 1/2 strength to save on nutes and not send my plants to nutrient burn hell.

So... since this is a 5 gallon bucket, I will do these all at half strength x 5gals:

5ml Flora Micro
2.5ml Flora Grow
2.5ml Flora Bloom

I really wish I could have afforded Flora Blend and Diamond Nectar. General Hydroponics has the stranglehold on Humic Acid. The other brand's don't really hold a candle up to their humic acid. I was thinking that if there was another way to get this crap, but I don't know. Also, sorry to drop brands... I don't know if that is acceptable here. Just remember folks, if you're dumb like me and find this forum after you got everything, and don't go with the vendors here, then you're dumb. You can tell that I am lazy and just buy all the shit I need before starting the project. That's what I did, but SUPPORT THE VENDORS because they need money and we need to support our dear forums! Ok, so don't kill me now. If any vendors have the humic hook up, then let's talk!

The other thing that I wanted to mention was that I have not yet pH'd my "from the tap" water and/or EC tested it yet. I do have both of those tools. You would think that someone that went through schooling for this shit would have done all this stuff and would have experience in growing hydro, but alas. I really did have a shitty time in school. Too many prideful professors. That and they knew that I wanted to learn about all this "cannabis nonsense" and they would have nothing of it because "muh research grants and backing". Well, ironic because now they teach cannabis cultivation where I graduated and look at how well legalization has progressed. Rant over... COPE

I will probably hook up the RO system and pH test and all that stuff to show what my water quality is like with and without reverse osmosis and with regular tap water. Comparison thread incoming.
