For this grow I will be doing (4) Blue Dream clones in my 5x5 grow tent, the setup is:


  • 5x5 Tent
  • 1000 watt light
  • 4 site Undercurrent DWC Hydro System
  • Environmental Controller
  • CO2
  • Water Chiller
  • House and Garden nutrients

I will be adding the screen in a week or so. The clones were rooted then vegged for a week in the aero cloner before transplanting yesterday to Hydroton.

Please feel free to comment.

This is gonna be good I got my chair pulled up!

Hey did you use co2 last grow? EDUT n/m I went back and looked.
How much increase percentage wise would you attribute to co2?

Thx Bassman, you got first!

To be honest I have run CO2 for every one of these last 3 grows except the first part of the first grow when I didn't have the CO2 setup yet. The other grows that I did were 10 years ago and were all pretty much failures and a lot of lessons learned on what not to do. This time around I decided to go all in and am now working on doubling my setup with another complete 5x5 setup. That will come in the next couple of months so stay tuned for dueling tents. Then I can do some experiments and side by side comparisons. I am really looking forward to experimenting.

Sentinel CHHC-4 environmental controller = ~$650
20# CO2 tank = $100
CO2 regulator = $150

CO2 refills are only $15 and a tank lasts me 1-2 weeks depending on the progress of the grow.

Damn that is a really expensive setup!
Ill stick to light and intake for now I guess

I have some seeds popped.
I went with 3 Herijuana and 3 Stank Ape
Going to buy some rockwool and tags.
I never grew either strain but I have high hopes.
I have only grown from seed one other time, and they were all males except for one out of 8 so I haven't done seed in a long time.

It's about to get a whole lot more expensive when I add a 2HP water chiller and all the accessories so I can get the other 5x5 up and running.

Good luck with the seeds, if I were you I would take cuttings of each plant and flower them to see which ones are females. Or you could just wait until their sex shows naturally, but I think that takes a little longer.

2hp chiller, now THAT is really expensive!

How long does it take to show sex?
I dont really have time/space to test flower.

Something is definitely wrong. The leaves are drooping and I can't figure out what it is. I originally thought that it was from some old TEA (10 days old) that I used but I have since flushed the system and refilled with clean R/O water, nutes, and fresh tea. My water chiller doesn't seem to be working as well as before and can only cool the water to 70-71 degrees. Air temperature is between 82-84 degrees. Here are some pics:

Problem: Signs of a cannabis calcium deficiency can be hard to pin down since calcium deficiencies are often accompanied by magnesium, iron, and other deficiencies. However, some of the major signs of a calcium deficiency are in the leaves which will display dead spots, crinkling, spotting, or small brown spots. Another sign of a cannabis calcium deficiency is new leaves will appear small and distorted with curled tips The insides of the plant and well as the flowers/buds may show signs of decay. Roots may show signs of bacteria and may be dying off or be under developed.

Solution: If the pH of your root zone is off, then your cannabis cannot properly absorb calcium through its roots so the first step is to ensure that you have the correct pH for your growth medium. Learn more about pH and cannabis. Different strains of cannabis tend to have different nutrient problems, but calcium, magnesium, and iron deficiencies often appear together in cannabis. Therefore many growers decide to purchase some sort of Calcium-Magnesium (often called Cal-Mag) supplement for their grow room in case this common deficiency appears. I have listed some available Cal-Mag supplements that I have used along below with some general information about each one. After supplementing with Cal-Mag and correcting the pH, you should expect to see new healthy growth within a week.

I just put brand new air stones in the system and I have been giving them CalMg so I don't think it's Calcium.

It was what I saw when looking at the pics.

Do you have any ideas?

Maybe they want a different water schedule?

I have no clue, I hope you find her problem!
