The Gas Chamber! Home of Killer Buds!

Edit: I changed the title to better represent the journal. This turned into an everything cannabis journal. My plans are to go all in on this journey. I’ll be using multiple different media and methods to grow photos and autos. There will also be seed production and breeding. As well as production of concentrates and edibles. All the things!!!

Im about 1-2 weeks from my 5x5 opening up and Ive been planning the next run. Im going back to living soil but Im going all in and looking for those frosty and terpy buds. I had gemini put everything together so others can make some sense of the plan.

Looks like a great plan with a very nice environment and the proper equipment.
Not being critical but, things think about. Realistically, you are growing organic, not in living soil. Living soil is trying to duplicate, the best we can indoors, the same structure nature provides with the development of an active top layer of decaying organic matter.
That duplication is not really viable in a 5 gallon container. You’re not going to replant in the same 5 containers, but dump it off into a tote or something, re amend and let it cook. That’s what I used to do!
I see nothing wrong with anything that you’ll be using.
While that is factual, it really just boils down to semantics. :wink:
I do see one area which could cause you some production losses. That is your planned temperature differential between day and night toward the latter of the life cycle. I understand the preservation the terpenes impossible desire increase purpling. The preservation of the terpenes is really based on your light on period temperature, since logically the off light cycle temp won’t be higher. Organic growing necessitates the need of high bacterial activity. Temperature is one of the critical factors in the biological activity in your media. Giving up 10 and 12 degrees it is quite a good hit, because there still is quite a bit of biological activity going on on the offtime period.60°F is quite the hit on biological activity.
Also with LED lighting, you should base your temperatures off of leaf temperature with a temp gun. Hopefully your fan controller a leaf temperature offset that you can set. I usually take that reading mid light cycle And I check when needed if I move the lights and or the plants grow higher.
You did mention CO2. I highly recommend not using augmented CO2 when you’re growing organically in such small pots. You could easily outgrow the capability of converting the nutrients over to usable formed to the plant. And that’s at the temperatures going to use. That only gets more so if you take advantage of augmented CO2 with higher ppfd and higher tent temperatures.

You’ve got a great plan man! It’ll grow some dank for sure!
I just wanted to point out a few areas you can make improvements.

Hey appreciate you looking at the plan and taking the time to reply.

I do know about what you described as living soil. My lease at the apartment is up in august and I’m wanting to move so no large beds. One thing for sure is that my soil will have living organisms in it. Like you said semantics and terminology.

I usually don’t worry about dif and just roll with it. I want to try playing with it this go. I’m hoping the heated root zone will keep the microbes active.

Infrared thermo ready to go. Definitely not ready for supplemental CO2. Only CO2 will be from the soil and me breathing.

Got the soil cooking. Mixing 45gals of material is not a fun part of the grow.

Whats the best format for this place? Multiple topics of different grows or one big topic with all content? My room has 4 tents going and they could all be doing something different. I grow autos and photos. Ive grown in organic soil and hydro rockwool. I plan to try other methods and media in the future. I’ll be making my own seeds and breeding down the road. Ive bought a press and getting into concentrates and vaping. I’ll also be making hash and edibles. Basically I’ll be doing all the things. With that in mind Im leaning towards one big topic but Im not sure.

I like those plans! Do whatever works for you. I know sttom and a couple other guys had single big long threads of everything.

Or you could do one thread/topic per tent.

I’m lazy so I’d be on the one place for everything. Maybe a separate thread for grow offs when they come along

It is wonderful to see you here. You are keeping the thread alive on the other side. Thank you so much for all the information you share with us

As someone who likes to see your grows I’d recommend posting everything on this thread. Easier for you and for us.

Wish I could edit the OP and title since this is going to be more of a cannabis journey topic rather than just the 5x5 grow.

Fastbuds Gorilla Cookies day 52 above ground. Massive amount of work on the canopy today.

This is going to be a learning process for all of us I’m still undecided how I’ll do it probably just one or maybe one for photo’s and one for autos to keep them separate but we’ll see. Do whatever you like best I’m down for whatever

@Hobbes may be able to help with this or tell us how to do it our selves

This inspired me to also do some 24 hour pumps on a couple of my tents.

I just came over to this site from the other and I have not created my own post yet, but I need to get that cooking.

Just did some big thinning out and getting ready to squish here soon

Hey thanks for following along. Continuous fertigation has been amazing for me so far.

Get that topic started I’ll follow along. Not a fan leaf left on that sucker. When you say squish does that mean you are doing the super crop and net too?

3 Likes

Yes Sir! Got her flattened out and the net put in half the 5x10 just now.

Running 24/7 drip, and even though it’s an autoflower I just read this really interesting article that talks about growing a plant its entire growth cycle under 12/12 that has me debating doing that as well.

I’ll probably just speak up in your forum here for a little bit until I start my next run.

I’ve got auto daiquiri lime from Dutch passion coming right now and I’m going to fill up the other side of this 5x10 tent with it. Super excited about that!

Hell yeah. Awesome job. That daiquiri lime can turn into a giant definitely something to be excited about. For sure keep us updated.

Ive done a little research into 12/12 but cant really imagine it being beneficial with autos. Did you find something specifically about autos and 12/12?

I ran 12/12 for most of my last grow because they were sharing a tent with a photo. They did well but I do think they didn’t pack on as much as they could have. @Man-O-Green has done some experimenting and I believe he settled on 18/6 being optimal.
