DWC: Seaweed Question

[Shaw]

*EDIT

Question answered! /applause


Answer:
Dissolve 8 dry ounces in 1 gallon of water to make the concentrate. For smaller batches dissolve 2 dry ounce per 1 quart of water.

Always dilute the concentrate down even further with water.

Dilute 1 part concentrate to 10 parts water.

Thanks for the list.

However, I am still looking for an answer to my question about seaweed as the only fertilizer for a DWC grow.

Anyone have actual experience with just using seaweed in hyrdo?

it seems to me that abudur answered your question. its a supplement, not a main fertilizer. i do 5 gal dwc and last grow i used GH's bioweed. half the buckets got the seeweed and the other half got foliar feeding. the foliar group were way more bushy and had more bud sites. also remember that seaweed supplements have sodium chloride salt, so flushing your buckets is important.

 

[Shaw]

abudur gave me a list of some options and what seaweed is yes. However, he did not answer the question I asked.

I have yet to come by a person who has tried to use just seaweed. I know seaweed is a great source for micro-nutrients but am wondering if it could be the only fertilizer. I know in theory we should not do it (this is why I ask this question), but I was hoping to find someone who had tried it, who has actual "hands on" experience with it.

Some questions:
Have you tried seaweed only for your girls?

How do you flush a DWC? Don't you just change out your bucket every two weeks?

 

[jammie]

i'm sure you could grow a plant using seaweed only since it does have some of the 3 major nutes(n,p,k), but its not going to grow as well as using a fertilizer thats designed for growing plants
flushing a plant in a dwc system just requires draining and filling with plain ph'd water

 

[Gebr'el]

i dont kno if this helps...........i use primarily himalaya salt and "liquid" seaweed (maxicrop) in a hand watered hydro system, basically i have a tray that i fill at 1-2 inches that 2 1gal buckets can sit in (wick method) but i have 5 small pots in.....i have a nitrogen only nute that is an addition to my own nute mix, my growth is wonderful. i have studied the compositions of both seaweed and the him salt, i figured they have just about everything i need for good growth, so i only add a lil bit of N to boost their profiles.

i am still in veg with execellent results and will continue this feeding program until the end of the stretch. then i will probably suppliment with a lil (P)hosphorus cuz i do believe there's enough (K) between the him salt and seaweed.

my medium is 60/40 peat/perlite with a lil bit of homegrown castings with out any lime and i havent had any ph problems....for now a least.

so though its not dwc but to let u kno there are some of us that utilize seaweed as "fertilizers" with success (not to start a flame fest, please) and foliar is a very big part of all my programs, i find it very very helpful. i hope this is helpful to you or anyone else.

peace n luv

[habeeb]

there is now way you can grow with only seaweed. seaweed lacks P and N

 

[Shaw]

Thanks everyone for your replies.

And thank you Gebr'el, you have given me some things to defiantly think about.

 

[abuldur]

hi shaw,

Farmers living in coastal regions usually gather seaweed to fertilize their soils.

All earth dwelling plants have evolved from their aquatic ancestors.

Earth dwelling plants have various npk ratios (so i guess the same thing goes for seaweed.)

In order to reach adequate npk ratios you might want to compost a wide variety of seaweed.

You can use this compost raw to fertilize top of you soil or make teas out of it (aerated or not).

peace

 

[Shaw]

Thanks abuldur.

However, I have answered my own question. Please check my original post for my edit.

Thanks.

 

[Gebr'el]

very tru abuldur...i am an islander and i learned bout the benefits of seaweed long ago from my grandfather who grew food for our family in a backyard garden. the vegies were always green and lush and i never saw him use pesticides and dont think i ever saw evidence of them being ravaged by insects either. i used to pinch off pieces of mustard greens as they were growing and munch on em...they were the best-est lol and oh...the sweetest bananas too. seaweed is powerful stuff we also make a drink out of seaweed we call "sea moss or irish moss"....makes the "pencil" stiff as steel hehe.....powerful stuff seaweed is truss me on dat one.

peace n luv

Found this for you might want to check it out (its from spurs reading list in the organic forum)

A simple general formula or recipe in fermentation can be done for plants. For example, seaweeds. If you simply infuse seaweeds (which are quite difficult to breakdown, therefore hard to extract active ingredients), you may not get a more potent extracted active ingredients. If you ferment the same materials by adding sugar or molasses, it is easily broken down (biologically) by microorganisms and thus making nutrient more available. Microorganisms get their energy from sugar in fermenting the materials. Most healthy foods are fermented foods. Through fermentation, food are easily broken down, enzymes created, nutrition improved. That’s the reason why fermented foods like yogurt or kimchi (Korean pickles) are more nutritious than plain milk or vegetables.
In making bionutrients, the simple formula is to add 1/3 crude sugar or molasses and mixed with materials to be fermented and extracted. For example, let’s take papaya fruit fermented extract. We chop as thinly as possible ripe papaya, unwashed and unpeeled. We then add 1/3 crude sugar or molasses to the total weight or approximate volume of the papaya materials. Put the materials with at least 50-75% air gap and cover loosely lid and let it ferment for at least a week. After a week, you will notice some molds and microbial infections and will start smelling sweet, sour and alcoholic. The materials are then strained and liquid generated will be your pure fruit papaya extract. You can dilute this with 20 parts water. This diluted form can be used as bionutrient, using 2-4 tablespoons per gallon of water. Again, this extract can be added to animal drinking water and feeds, to compost pile or sprayed/watered to plants leaves and roots. This will be a good source of nutrient for plants or animals, and also for our beneficial indigenous microorganisms. Papaya extract is good source of enzyme pappain, beta-carotene and Vitamin C for example. So extract any plant material and just try to find out what kind of nutrients they have you can use for animal and plant nutrition. Should the materials you intend to use for extraction do not have much moisture (as compared to our papaya fruit example), you may add water enough to the level that will moisten all the materials.

Great info!

Thanks again!
