Growing with Gaia Green, what else is needed for the soil?

[MaryJane321]

A simple explanatory description. I contacted Gaia Green as well as Promix to ask the following question. Both companies have been largely useless at resolving the issue.

I have Promix HP, Gaia Green fertilizer (444 as well as 284) and GG earthworm castings. Is there ANYTHING ELSE I'd need to add to my soil to ensure my plants receive adequate nutrition through until harvest?

A little extra aeration never hurts and I like a bit of oyster shell flour for extra calcium if your growing indoor under LED but just plain Gaia green castings and promix works fine

I will be growing indoors under LED's.

So just perlite and oyster shell flour? Nothing else?

That’s all I usually add. I keep some liquid fertilizer on hand just in case I want to give them a boost. I usually use medi one.
I’d check out the Gaia green thread in the organic section, lots of good info in there.

Post in thread 'Official Gaia Green Grow Method'

Mar 6, 2025

Hey all,

I think that this is an important topic and I haven't seen a thread that's really dedicated to this.
Whether you use Gaia Green or another similar brand (like Dr. Earth), it would be great to have a place we can consolidate our process info.

I'll start here. Throw darts at it and let's come up with a process that can work well in most cases.

Germinating and Veg:

• Mix your starting soil with Gaia Green All-Purpose Fertilizer 4-4-4 (or similar) according to the package directions.
• Use this in your red solo cups and in your one-gallon pots.
• After three weeks...

Here’s the thread about growing with Gaia Green. Sorry, I haven’t used the stuff, so I can’t offer advice.

How is the grow going?

 

[Smokenpassout]

I use Gaia exclusively now in soil. I would suggest one more product, their glacial rock dust. The plants just perk up to a new level and the color! Something in those trace minerals! my last harvest of purple punch was super sweet and grapey. I use the grow and bloom sparingly in happy frog/perlite. I do not amend it according to their recipe. That’s more for reusing dead soil. I simply do 70% grow and 30% bloom when plants are a good month old. Top dressed at 1 tablespoon per gallon of pot size. 3-4 weeks later at flip I top dress again at 50% bloom and 50% bloom. Then after about 4 weeks of flower, I add a final top dress of 70% bloom and 30% grow. 3-4 more weeks and I’m flushing.

I feel like GG is a cal:mag supplement away from being the be all and end all. Have yet to successfully run an entire crop without needed some kind of added fert (jacks tomato’s is my go to). Honestly too bad they couldn’t boost that call/mag level which is somewhat surprising given the ingredients listed (ie. feather meal).

Add some cal-mag supplement to your soil next time. Dolomite Lime , Glacial Rock Dust and Volcanic Rock Dust, are typically good ways to get more Magnesium into your plants diet, and gypsum/lime, oyster shell flour, and bone meal are great ways to get more Calcium into your soil. Just keep liming levels in mind.

That was my point…Gaia green is listing those exact ingredients you mentioned yet it seems to still be cal:mag def:

Fishbone meal, feather meal, alfalfa meal, phosphate rock, sulfate of potash, insect frass, soy protein hydrolysate, gypsum, seaweed meal (Ascophyllum nodosum), oyster shell, greensand.

Gaia pretty much also sells all of those amendments individually, so you can tailor your feed/ soil mineral content to your plants/growing environment. If you find their Grow & Bloom lines lacking in adequate Ca/Mg levels for your situation, it’s up to you to make those corrections. Your mileage may vary whether you’re in real soil or a potting mix.

I usually mixed the 444 with frass and the bloom.Then the 1 cup per 5 gallon of mixed soil.
Rock dust,dom lime,ewc and worms,compost,peat,perlite.
Some of my soil is over 4 yrs old now.Seams to work.

How much Rock Dust are you guys using? In the past, dudes were advising crazy amounts, up to 4 cups per cubic foot of soil.

How are you using it? Just adding it to the all in one fertilizer mix, or applying it separately?

Cant remember exactly but yes 4 per sounds right,I remember doing 8 cups which is the whole container.
Id mix about 20 gallons at a time.

 

[myke]

I always did 40 peat 20 ewc/compost 40 perlte. Top dressing would include compost/ewc so i was careful not to over do the ewc/compost when mixing.

 

[cdgmoney250]

If you were mixing into soil as a stand alone, I would add at least 2 cups per cubic ft. If you’re adding it to one of their blended lines, I might only add 1 cup per cubic foot or soil.

I apply the rock dust as a top dress at about half of what they suggest. I put the first half in along with my first feeding of grow and bloom 70/30. Then about three week later I put the second half of the glacial rock dust in with a plain watering. Plants seem to perk up and respond well to the stuff after each application.

Does that not make the top of your soil crusty doing it that way? I've always just pre mixed it in..

Azomite or some form of glacial/rock dust would help. Are you growing photos or autos?

I use AZOMITE at a rate of 1 Level TBLSP per Gallon of Medium. In my case. Promix BX. Every Month.

I too have found Gaia Green to be lacking in Mg/Ca, but not until early-mid flowering. It was ok, until then, and then they got a huge deficiency, which I corrected.
One solution is to top dress Epsom Salts 1 TBLSP , every 2 weeks. 1 TBLSP G/M Gypsum, every 2 weeks.
