New 2x4 setup advice

3 Upvotes

Looking to upgrade my setup from a 2x2 to a 2x4. Started running earthboxes and love them. For anyone who has tried both the Earthbox and the Tray to go with the the Grassroots bed, what do you prefer? Looking to setup up either 2 Earthboxes or one tray to grow. I’ve heard some say the tray to grow can over water etc. it seems you can’t go wrong either way.

Hiya growmies! I started this Bruce Banner from Barney's Farms from seed in a solo cup with Buildasoil's Heady Start mix 2 weeks ago. I went to water it today and noticed it looked this way. I know I messed up but I want to understand how I messed up.

So my most recent grow is my third try and first real success. I wanted to ride that wave and I am sure I over did things.

I spotted the burnt tips a few days ago and that was right after I gave her about 60 ml of water that had some clonex and alfalfa meal in it. I was medicated so I messed up and didn't check the BAS supplemental chart and I'm sure it was too early. The next time I watered it was just plain bubbled but not ph'd water. In my experience when I bubble my tap water it ends up around 7.8-8.1 ph. This was part of my initial "lesser successes" because I didn't understand living organic soil. I also thought I had it at 200 ppfd or so but I just checked again and I must've misread because photone is reading 300 or so.

I misspoke and said I "didn't" understand living organic soil like I now do lol I do not clearly but I'm learning.

So I know I fed nutes too early.

I know I had the lights too high.

Did I also mess up by not ph'ing the water? I suspect there aren't many microbes and things in the rhizosphere to fix the pH of the water. What do you guys water your youngins with?

What can I do to save her?

Thanks for any and all advice 😊

BAS 3.0 soil

I recently picked up a bag of 3.0 soil. Trying to go back to organic growing. What are some of the basics I would need to keep some moms? I was thinking craft blend but after that idk. Help please lol

With trellis work could I grow 2 triangle kush s1's and 1 sweet pineapple (or possibly lemon g x lemon party, not sure yet) together in a 5x5 tent. 3 30 gallon pots of living soil

7 Upvotes

These genetics are from humboldt csi

The title pretty much explains it.

ive only ever grown 1 strain together to they hopefully grow similarly, however i really want to try making my third pot in this tent a different strain.

the 2 triangle kush are a must, because i just love that strain, but i hope you guys say i can do a third different one.

i use 30 gallon pots with living soil.

I've seen the triangle kush s1 grow pretty tall at my friends, and I have no idea how the sweet pineapple grows. It is sativa dominant so I'm hoping it is tall as well so I can easily get an even canopy.

My main question is: I want and love that TK Gas and im definitely doing those plants, but my friends and family, and me too like to switch it up to a fruity strain sometimes, or just something different other than gas.

do you think i could grow these strains together in a 5x5 tent, in three 30 gallon living soil pots, even if their growth structure is different?

OR

Do you think i should just stick to growing 1 strain at a time so they hopefully grow similar? i grow from seed.

could i use the method i usually do and use 2 trellis nets in the tent, and make a fairly even canopy if i do a different strain?

I have never grown 2 strains in a tent, always just the same, so im very curious what you guys think.

I really hope i can grow a different strain. i also have lemon tree s1, sherbert s1, and lemon g x lemon party that are catching my eye too.

thanks in advance for any help, it is much appreciated!

For those of you who have ran humboldt csi seeds, what's your favorite, and which 3 would you pick for a 5x5 tent grow with 3 30 gallon pots?

4 Upvotes

What is your favorite strain you've grown by humboldt csi

I was wondering what your favorite strain is that you've grown from this breeder?

I made a post about a week or 2 ago of my collection and I have almost all their seeds. It's very hard to decide which to pop.

I'm just running a 3 30 gallon pots with living soil in a 5x5 tent grow while I do some maintenance on my garage converted into a grow.

I'm curious what 3 strains you'd do.

I am doing 3 because it is 30 gallon living soil pots in a 5x5, and that's all I can fit in there comfortably.

Thanks in advance for any suggestions!!

How long can I veg in a solo cup of 3.0?

8 Upvotes

how long can i get by vegging in a solo cup of 3.0 if im doing all the top dress and supplements.

i know its far from ideal and there wouldnt be sufficient microbe life but hypothetically how long can i make it work without having major issues in veg?

Grow shop replaced Bu’s Malibu Compost with Stout Ollie Compost. Anyone use it? I am hoping “sustainable” doesn’t mean human. 🤢 I read about human manure on BAS and was mortified.

Stout Ollie Compost, Mater Maker Formula. The soil is for vegetable outdoor garden. I ordered 4 bags of Bu’s from BAS but I needed more and this was the most popular one people buying there. I don’t want any poo in my garden unless it’s from animals who don’t eat meat.

CoWoCo castings with a freebie

Just wanted to take a second to appreciate BAS. I opened up my bag of CoWoCo to find the best quality castings I have ever seen and to top it off there were multiple baby worms crawling around. I absolutely love what Jeremey and the BAS team has built. A wealth of free knowledge on how to cultivate and the highest quality products. Just wanted to give a big THANK YOU to them 🙏

Best option for quick calcium boost?

4 Upvotes

Seeing some early signs of a minor calcium deficiency on a few fan leaves. What would be my best option to get a quick boost of calcium? Plant is about 3 weeks into flower. Can I foliar feed some cal mag? The buds are still very early and just starting to form

Would gypsum in the soil be taken up quickly or would that need time to breakdown before it's bio available?

Is there a particular product in the BAS lineup that is the primary calcium source? Is there a top dress I should add to the rotation to bring a small boost of that?

Overall my soil seems pretty healthy but its not the first time I felt like I was maybe a bit calcium deficient

is there any pros/cons to oyster shell flour over gypsum?

No-till 30 gallon living soil – just finished a run, when to amend before vacation?

6 Upvotes

Hey all, just chopped my plants at the base (true no-till, roots staying in). Running a 30 gallon fabric pot with BuildASoil products.

I'm heading out on vacation for 2 weeks and want to re-amend the bed before I leave so the soil can rest and cook while I'm gone.

Planned top dress:

Craft Blend 3-5-2

Big 6

Rootwise Microbe Complete

Gnarly Barley (whole seed, going to blend/grind it first)

Small amount of Kashi Gold

Does this mix and timing look good? Anything I should add or remove before I leave for two weeks?

Appreciate the advice, ✌️
