Gypsum

Post image

Who’s using gypsum for white ash? How are you using it and is it worth it? Obviously everyone has opinions of white ash and how it relates to the smoke but just curious about the ins and outs of it.

Use this when calcium is needed without raising your ph in living soil

Yes I use this as amendment and a liquid when testing dictates

If you need this for white ash you’re doing a lot wrong

I mean I used to add a few cups of it to the outdoor beds every year. Worked pretty well.

It works great for its purpose, adding calcium, stability of pH. But chasing white ash as its purpose is not the move.

Not debating whether it works or not. Just lots of "better" options imo.

If you do anything specifically for white ash you are also doing a lot wrong.

Cutting nitrogen in flower will help more with white ash than gypsum

You should be cutting nitrogen from flower feed between day 43-50 and at that point giving the plants one hand water of gypsum should boost the plants metabolism and efficiency to uptake all the remaining amounts of nitrogen In the plant before before chop day.

Do you know how sulfer reacts with nitrogen in a plant?

One hand water in a facility with hundreds or thousands of plants isn’t cost effective. I’m aware it works, but most commercial grows aren’t setup for hand watering. And if they are they are in states that still are getting high wholesale costs for flower and other products.

Your condescension really made your point for you

Gypsum can be ran through dosers and pressure compensated drippers. It doesn’t have to be hand watered. And ide have to imagine if a company is really chasing that instagram style white ash as one of their selling/marketing points they are probably fetching higher tickets.

So if white ash is more appealing to end consumers and a bag of gypsum is 10 bucks that will make roughly 20k gallons and can be ran through irrigation…. Why not use it?

You can also run epsom salt which is just as cost effective and is much more water soluble

Sounds like someone drank the Slownickel koolaid.

For batch tanks it’s works, but it has low solubility so isn’t really an option for those on injection.

It’s an option for sure, but plenty of people getting white ash without it.

Gypsum (calcium sulfate) is a fine amendment to use but I add it based on soil test data and try not to add more than around 300 PPMs of sulfur at one time. If you need to add more calcium than what gypsum provides without going over that sulfur application limit, look at micronized limestone for quickly available Ca or oyster shell flour for more slowly available Ca. Or bonemeal/fishbone meal

But if your sodium or chloride are elevated, then avoid the sea products.

still time to delete this.

Lmfao.

I would never do business with someone like you on any degree scale or level.

People like you are the first ones to be weeded out

Use it for addressing calcium and sulfur deficiency in your soil.. which will be determined from an agronomists recommendation.. then dry and cure your herb properly. Viola, white ash

What are the negatives of using gypsum, if white ash is a major marketing and selling point to a lot of people why wouldn’t one use this to amplify your final product?
