I am a begging farmer and I have been in using your products and up until now they seem to be really good. My algen extact has seem to maybe went bad??? i was wondering if this is possible?? The liquid seems to have like gotten thicker. my plants seem not so lush compared to in the begging. So i guess what im saying is if i dont use it fast enough does it go bad???? I bought a liter about 6 months ago and there is about half of it left
It should last a year after opening aside from excessive heat or cold exposure.
hello, is the algen extract used during flowering? your feed charts on the website and the feed charts available in the brouchure are not alike. on the website it does not mention the use of it on any cycle for flower. in the brouchure feed chart the mix rate is 1ml/L throughout flowering cycle. can you please clarify? 13 year advanced nutrient user switched 3 months ago and never look back!
Hey Jay,
First make sure your looking at the US H&G website because UK likes to run algen extract the whole time. Here in the US we only use it in veg.
ALGEN EXTRACT- Ascophyllum nodosum: cold water extracted seaweed to keep as much biological life intact as possible. Seaweed extracts have ziatine for cell growth, vitamins, natural hormones, amino acids, proteins to strengthen biological and plant life, and trace amounts of micro nutrients. New dose:1-2 ml per gallon.
Happy Growing! Rob
why are the schedule and dosages different in the UK from the us
Hi Jared,
The factory and scientists have formulated these doses for the differences in water and climate and probably some other things I don’t know about. Please follow the feed chart for the country you are in. Peace!
Alan
I have all the house and garden products except for algen extract, would you say its an important additive? Basically i’m just looking to save money where I can
Thanks
I grow in promix and use your soil a and b. I also use ur additives. After I mix up my nutes I like to let them sit for 12 hours with an airstone to help mix, oxygenate and help get rid of the chlorine. Can I use an airstone to aerate your nutes ??
TYVM for your time,G
Hey Gord,
Its always best to try to remove the chlorine with air before you add your nutrients. After adding nutrients I feel its best to turn you airstone down really low or even better is to add a recirculating pump to break the water surface.
Happy Growing! Rob
Hey guys,
Thanks for coming to the expo here in Long Beach. I’m trying your product line for the first time. I picked up your 40 page booklet and read most of it. I’m curious to know why the Algen Extract is crossed out of all your feeding charts in the back of the booklet.
Thanks again.
Hi Scott,
The factory reformulated the Algen Extract just after the books were printed. The dose is 1-2ml/gallon and it used to be much stronger. Peace!
Alan
Can Algen Extract be used in a recirculating system?
Hi Miranda,
Yes, Algen Extract can be used in a recirculating system. Peace!
Alan
I am mixing by the litre, could you please tell me how much to add per litre, thanks a lot, it would be very helpful. Do I use it during flowering and vegetation. Waiting to hear from you.
I am from the UK.
Thanks a lot, Martin.
Hi Martin,
I can’t understand what you’re asking. Please clarify. Peace!
Alan
how much algen extract to use for a foliar spray? same amount 1-2 ml per gallon? or more? somebody told me 4-5 ml per gallon of spray.
Could/should I just use magic green to foliar spray instead? does magic green contain same/similar additives for the cytokinins (sea kelp extract?) as algen extract? and probably other goodies as well.
Thanks
Hi Adam,
Algen Extract is not meant to be used as a foliar spray. Whoever told you that is wrong. Magic Green is the House and Garden foliar spray. The proper dose is 5-10ml/gallon used every other week. Peace!
Alan
Hi, I use your complete line of House and Garden except for Amino Treatment. I was curious if using Dark Energy with your line would be alright or if Algen Extract having Amino Acids and Vitamins like Dark Energy really makes it obsolete?
Hi Cassidy,
Algen Extract doesn’t have aminos in it. If anything, Amino Treatment might have some of the Algen Extract properties in it. You can use Dark Energy with Algen, but I wouldn’t use it with Amino Teatment. Peace!
Alan
So you just said it’s not supposed to be used as a foliar spray but above under applications For the product it says foliar spray…?
Hey Jim,
I’m unclear on what exactly you’re talking about, please refresh my memory. Peace!
Alan
