Making you weed more blue

I just found out that flower growers make some flowers go blue by adding baking powder to their soil for its aluminum sulfate content.
Apparently soil that has been treated with this helps to lower ph levels in garden soil and can sometimes cause flowers that are pink or white to turn blue.
Has anyone else ever done this or heard of it?:blsmoke:

im starting a grow in a few days.. and one of the plants is going to be a "test plant" ill try it if you want?

Yeah man i am also going to test it and see what happens.
Real problem is i don't know how much to add???:confused:

i know if you grow a potato in water with blue food colouring the sprouts and leaves will have a light blue colour i dont know if this would work with a hydroponics system, interesting experiment subject though

No thats not what this is about.
Using food coloring is not acceptable to me anyway.
This is a soil additive that helps to turn the plant blue naturally.
No rip of stuff.:blsmoke:

Some marijuana have pheno's that are naturally purple or blue. Other times you can cause coloring by exposing to night cool temperatures.

I hope this helps

I already have blue weed.
This technique does nothing to alter the weed in any way and does not dye it a different colour or make it blue due to it being to cold.
The aluminum sulfate content of the soil allows the plant to take up this element through its roots and sometimes helps to change a white or pink flower into a blue one.
Here is some guy talking about turning hydrangeas blue.
I dont even know if it will work on weed.
I will try it using the aluminum content of baking powder on a weed that i know is blue already and see if it goes bluer and on a weed that i know is not blue and see what it does.
Im going to add 1 teaspoon of baking powder a week to these 2 plants water and see what happens.


To obtain a blue hydrangea, aluminum must be present in the soil. To ensure that aluminum is present, aluminum sulfate may be added to the soil around the hydrangeas.

Authorities recommend that a solution of 1/2 oz (1 Tbsp) aluminum sulfate per gallon of water be applied to plants (which are at least 2-3 years old) throughout the growing season. Important: Water plants well in advance of application and put solution on cautiously, as too much can burn the roots.

To make the aluminum available to the plant, the pH of the soil should be low (5.2-5.5). Adding aluminum sulfate will tend to lower the pH of the soil. Another method for lowering the pH is to add organic matter to the soil such as coffee grounds, fruit and vegetable peels, grass clippings etc.

If the soil naturally contains aluminum and is acid (low pH) the color of the hydrangea will automatically tend toward shades of blue and/or purple.

The choice of fertilzer will also affect the color change. A fertilizer low in phosphorus and high in potassium is helpful in producing a good blue color(25/5/30 is good. Potassium is the last number). Superphosphates and bone meal should be avoided when trying to produce blue.

After stating this with much certainty, I hasten to add that it is virtually impossible to turn a hydrangea blue for any length of time if it is planted in soil with no aluminum and that is highly alkaline (chalky). One would have to be very diligent in keeping the soil properly conditioned as stated above.

Perhaps the best idea for growing blue hydrangeas in an area with alkaline soil would be to grow them in very large pots using lots of compost to bring the pH down. The above suggestions for bluing would also work for a potted plant. Reduce the strength of the Aluminum sulfate to 1/4 oz per gallon of water. In a pot, it will be much easier to control the requirements for bluing.

One last suggestions for those who are serious about this process. It is important to have your water tested so that it will not "contaminate" the soil that you have so rigorously balanced. The pH of the water should not be higher than 5.6.

Planting hydrangeas near a concrete foundation or sidewalk will often affect the color since the pH of the soil may be raised considerably by lime leaching out of these structures, making it difficult to obtain blue.

i have grown before using bubbleponics.
my weed turned out looking good but it did not get me very high at all.
actually it barely got me buzzed off of one whole blunt
i was growing in my closet using stealth hydro bubbleponics
iwant to grow indoors though

Yeah thats for adding pure aluminum sulfate powder to outdoor plants at a high level of 1 tablespoon per gallon because of outdoor conditions.
Apparently because of rain and other outdoor conditions this needs to be put on this strongly and fairly often after 2-3 years old as the substance of pure aluminum sulfate powder even in water can burn of the roots of young plants which is why i just want to increase the blue of my already blue weed with the small traces of aluminum sulfate that are in baking powder.

I am going to mix some baking powder into my fresh soil say about 10% baking powder and then water with 1 teaspoon full a week in their water and see what happens.

I don't recommend anyone to try this or do so at your own risk.
Dont blame me if your plant dies.
For all i know it will either do nothing at all or kill your plants so watch this space if you want to know what happens to mine first.

My weed is already blueish and i just want to see if growing in soil with a higher aluminum trace element can help the blue to be more pronounced and brighter:blsmoke:

Do you have a grow journal or logging this experiment anywhere? I'd like to sub to it, thanks.

I currently have room for 2 test plants in my new grow tent and would like to experiment with this also. :leaf:

Cannabis plants are purple already, when exposed to cooler temperatures some of the chlorophyll dies, uncovering the blue/violet colors beneath. Strains like Blueberry and Mendo Purps are colored naturally trough genetics. You can cause deficiencies in late bloom that will give you good violet, sometimes maroon colors, this is done because the grower is focusing on maximum production and potency, not necessarily for the color. Sometimes when a pot plant has had a 'dry spell', the next time they get watered they will suck up more material than necessary out of a survival technique... maybe this could be used to suck up a food coloring or the baking powder? ...generally plants only intake nutrients and chemicals that they need/use, unless there is nutrient lockout/pH imbalance or irrigation problems.

Usually certain strains have the ability to change color when the temperature stays below 50 degrees Fahrenheit. I grow alot of blueberry autoflowers and as long as I keep the temperature just right they will turn blue
