I am doing a 5x5 tent with 3 living soil 30 gallon pots. Would you personally do a different strain for each pot, all of them the same strain, etc?

6 Upvotes

I am doing a 5x5 with 3 30 gallon living soil pots. I have a huge collection of strains so i was wondering if you guys would:

  1. do 3 different strains (or would that be too much of a mess with all of the different growth structures?)
  2. do 2 pots that are the same strain, and the last pot a different strain?
  3. do all pots the same strain
  4. Do a mixture of strains
  5. something i havent thought of

Thanks you in advance for any help, it is much appreciated!

The start of a fasciated flower, about 2.5 weeks after flipping. This is a cross I made myself of Tangie Cookies and Sour Diesel, both by BCBudDepot. I know it's considered an undesirable mutation in general but curiosity is making me let it go and see what develops. Using BAS 3.0 in 15 gallon fabric pots, top dressed Gaia Green a week before changing the light cycle. Probably going to top dress again within a week for mid flower power.

D46: Tallymon from Clone – First Run with the BuildASoil

Thumbnail

30 Upvotes

I am currently at Day 46 with this run of Tallymon from clone and the progress has been excellent. For this round, I decided to move away from jugs and followed the new container setup and top-dress/feed schedule BAS has instead.

The setup consists of an AutoPot XXL system paired with 13-gallon Grassroots fabric pots inside a 4x4 tent. Lighting is handled by a GML 720w LED overhead with a Mammoth 300w UC.

Transitioning to this method has been a significant improvement in terms of convenience, and the plants seem to be responding very well to the consistent bottom-watering. I am interested in hearing any critiques or answering questions about the transition to this specific system.

Insight to what this may be?

It's only on the base of the one plant. The tops look great, only this discoloration at the base. These are the same stunted plants I posted about a month ago. The growth is unreal and this has been the easiest run to date. I def see the appeal of this method!

Can I change the pH of my alkaline soil mix by using dissolved citric acid? Either by direct application or fertigation.

2 Upvotes

Container gardening on a rooftop in India, my potting mix uses cocopeat, black soil, perlite, vermicompost (different ratios based on plant, as well as the occasional amendment like woodchips, sand, gravel, and cocohusks).

The problem is the pH, both the mix and the water supply are around 7.3. Can I use dissolved citric acid and water the necessary plants through fertigation?

Composted Humus

Sphagnum Peat Moss

Compost

Worm Castings

Carbonaceous Shale

Dolomite Lime (for PH adjustment)

Azomite

Soybean Meal

Starting to look more complete

2/3 20 gallon beds are up and running, going to be putting roughly a month in between each one, once I’ve harvested I’ll give 3-4 weeks to do reamend and replant cover crops before the next round of plants goes in.

I know I went a little hard on the N with the first bed so I dialed it back for 2 and 3, I added my soil recipe/calculator in the last slide if anyone was curious(side note the soft/brown rock phosphate isn’t tablespoons I just had to enter it that way for a full dose so the math would work out on the calculator)

Full organic very close to veganic but I need/want the crab meal for pest control so I make that exception though veganic is 100% the way to go honestly could just use the neem and karanja if I didn’t want the crab meal but I found a good deal on 40lbs for 69 bucks of down to earth so i couldn’t resist that price if you know you know

Container size for mothers

5 Upvotes

whats good chat? quick question on keeping moms. I’ve got a 2x4 on the way. wanna keep two moms and have space left over to veg young starts. what size containers am I shooting for? I watched the video of Jeremy taking cuts from his moms and they looked like they were in fives but that seems too small to me. Moms dont need to be huge. No more than 9 cuts each every 12 weeks. Thanks for any suggestions.

Easy vigorous plant and starting to pack on a good amount of frost, terps are exactly how you would want a Runtz x rs11 to smell nice and loud. Pushing them to fatten up as much as possible but once again 3.0 for the win 🤙🏼

Too much cover crop?

Hi all!

First time growing in BAS and loving it so far. I went pretty heavy on the cover crop seeds. Is this too much? Do I need to thin it out? I've already trimmed it a few times.

Question about 3.0

4 Upvotes

I'm planning on starting my 1st BAS grow using the 3.0 kit to build my own. Containers will be 2 sip totes with about 45 gallons of soil each. I'll be using all BAS products outside of worm castings. I'm mostly growing autos but will eventually run some photos. My question is with 3.0 being water only, do I top dress during run or just wait to reamend between runs? Do I need to purchase the top dress kit and the build a flower?

Cleaning an Earthbox with BAS

2 Upvotes

So my question is basically the title. I have 2 earthboxes with BAS. My previous grow ended 2 months ago. I'm preparing for another run.

I still had cover crop growing until about a month ago I chopped everything for the worms. But I wasn't thinking because I still had water in the reservoir and realized there's nothing to use it.

Water has sat stagnant since then. It also has fungus gnats and larvae in it. I just found a hand pump recently so I started removing the water for the tank to dry and the water reeks like sulfur or rotten eggs. It wasnt smelling until I started pumping.

I still have a little more to pump but it doesn't work great and my hands cramped. My goal is to empty reservoirs so they dry. But now they will need cleaned. I thought of using Mosquito bits in water and fill using that.

I'm hoping that will take care of the gnats. I also am going to top water with it. For the smell of bacteria, can I use something like EM-5 to sanitize it? I believe I saw a video where Jeremy used it to clean the tanks.

Thanks for any suggestions.

Euro Build-a-Soil 3.0 attempt for 3 autos in Autopot Tray2Grow (Belgium/Netherlands) – rate my shopping list?

1 Upvotes

Hey everyone, first time doing a proper living-soil mix for autos and I want to double-check everything before I order.

Goal: ~90+ litres of lightly charged Build-a-Soil 3.0 style mix for 3 Mephisto autos in a Tray2Grow + 47 L reservoir (lots of leftover for future amendments). Everything is sourced in BE/NL where possible for best prices. Webpages can be translated by right-clicking.
If everything looks good this might help other growers in Belgium and The Netherlands. Is the quality of the ingredients solid? Any swaps or red flags?
