Least Algae Nutrient

Weed Killer · May 26, 2015

I've got a flood table for veg only and it sucks to clean, anyone have any suggestions for nutes that don't grow as much algae?

I've used house and garden and if I wanted to start and algae farm that is what I'd go with.

been using dyna-gro less algae happy plants.

trying jacks now

any other ideas for veg nutes?

There aren't any. if it has nitrogen algae will grow.

You need a top plate, white/black plastic to block all light from hitting your Nutrient solution, in all areas, algae is a plant like cannabis, it loves food and water, add light and it just grows.

Weed Killer · May 27, 2015

With all due respect, that is not what I asked, I asked if someone knows a nute that grows the least algae, not one that algae won't grow.

Like the examples I gave, dyna-gro grows less algae than h&g. Is there a nute that grows less algae than dyna-gro.

A cover is not practical for my application, plants are constantly being moved, removed and added.

What both of us were trying to say is that any nutrients that grow weed, will also grow algae, there is no formulation that will feed cannabis but not algae AFAIK.

Sure you can buy anti algae products from pond shops etc. But these will be anti cannabis too.

Maybe think about some kind of individual shading collars?

What I am trying to say is I understand I will get algae growth when using a hydro nutrient, but some nutrients grow more algae than others

you made that part clear, but these other fellas made it clearer. dont be a fuckwit.

Weed Killer · May 27, 2015

clear as mud, and thank you for your kind words

Look into running sterile. There are a number of products used, bleach being the most common.

You've got a way with people

So you want to change your nutrient line based on algae growth on your tables? I'll bet the guys at the hydro shop love you.

No, all nutrients are equal as far as I know/understand

Re Bleach, good for killing anaerobic bad bacteria, but does it (in the correct dose) kill algae not cannabis? Doubt it but would be interested to hear different.

use some pond cleaner product or any other enzymes to keep the algea levels down

I also think that the type of nitrogen will play a role, think of the nitrogen cycle bacteria convert urea to ammonium and then in to nitrate that the plant uptake..

so a 100% nitrate based fertiliser should produce less algea

Also you have much better uptake of calcium and magnesium and other positive charged ions with you N represented by 100% nitrate

mike: thanks for the reply, I have pool shock for cloners, might give some a try in the rez

trich; it takes a full day every month to clean my veg trays, so yes I would change my nutrient to save some time.

Chaos: H&G grows more algae than anything I have ever seen, still use it in flower but with dyna-gro about a 1/4 the algae of h&g.

DK, you hit the nail on the head, I think the ammonium/nitrate ratio is the key, but I don't know a straight nitrate nute?

ChaosCatalunya · May 28, 2015

Interesting observation WK, I have never heard this before.

On a side note, I remember my tropical aquarium had a polyester wool filter that took a good percentage of the algae away, effectively it just pumped the water through a box, low fi but worked.

Not to bash on canna specific nutrients, but most are pretty lame, since they have to be pretty basic so pepol dont fuck it up..

But any professional fertiliser company that specialise in greenhouse crops has many 100% nitrate based fertilisers, you just have to rember that it will raise the pH of your medium and hence you gotta know what you are doing and if you live in a place where your local water scource is loaded with calcium you will have a dobbel effect and your pH medium will raise and cause micro nutrients to become less bioavaliable so, that why u need some ammonium in there to counter that effect, since ammonium will reduce the pH...

So you will see on proffesional fertilisers they will list the potential acidity or alkalinity of the fertiliser pr hectar or in other ratios..

If you choose to use a 100% nitrate based N fertilser you need to add buffer that solution with some acid so you balance the raise in pH that follows a 100% nitrate fertiliser...

An added benifit of using a 100% nitrate based fertiliser is that you dont have troubels with ammonium posining but the draw back is the raise in pH of your medium, hence the acid is handy to keep the pH down.

Weed Killer · May 28, 2015

On this last change I'm trying some jack's hydro, just looked it up and the hydro formula is all nitrate but the cal-nit is 1% ammonium.

my tap water is very good so it should be a good buffer, I use a nutradip meter and check it several times a day.

Thanks

Dkgrower · May 28, 2015

Good luck and pls rapport back with your finding regarding the effect on algea growth

Mikell · May 28, 2015

Glad to see this went somewhere and wasn't bogged down by the peanut gallery.

As for bleach, I've no idea on that. Zero experience with hydroponics, but I know some use it or other products to run sterile.

when u use dyna gro do u have those rocks that are in the bottles? or at least the sound of rocks scratching the bottles. i got a bottle of Foliage pro and it sounds just like its got pebbles in the bottle. i suppose that is some the nutrients that has fell out of suspension.

Weed Killer · May 28, 2015

DK; spot on with pH rise, up .5 overnight. Dyna is a bit more stable.

Mike; have used bleach in the past in dwc, now I use shock in the cloners but haven't had any problems with the tables so haven't used it in them(yet).

Kygi; I have had dyna chunks, I always try to shake the shit out of the bottles before use.
