What if?

Admin, I use Canna Coco products. I grow in coco fiber with 5%perlite added to 50l Canna plant medium. I grow in 2 gal. buckets with 1000 watt sodium. on a move track. 4'x4' tray 9 plants per grow. Can I add Femeg GuanoKalong? I use all canna products at present and I get average1.75 oz. from 2 gal container these are clones not seed. If I can use it what amount would you suggest? Thank you

[admin]

Hi Smokesalot. Good to get some feedback on this lot. As I said at the beginning, these reviews are not based on personal experience but on info found online. It was just an effort to get all of this info in one place.
Having said that, I have spoken to people who have used GuanoKalong to great effect. However they have used it with soil so I don't know how it would work with coco. Maybe ask Femeg and see what they say to it.
Off the top of my head I would say yes you could. The properties of guano have long been known to be pretty amazing, but I couldn't vouch for it personally.
I'm intrigued by the Ancient Organics range of nutrients (see above, same thread) which are totally based on guano, but they are difficult to get hold of where I am.
If you decide to give it a whirl let us know how you get on.
More nute info/reviews to follow.......

Hesi NL

Dutch hydroponic specialists Hesi get their name from a magical plant food recipe. With over fifteen years’ experience of working with hydroponics, Hesi nl have expanded dramatically from a small local business to an internationally important hydroponic nutrient supplier.

As you might expect from such a company, Hesi nl offer a wide range of hydroponic nutrients and equipment to offer solutions to every eventuality faced by the hydroponic marijuana grower. They have, however, become particularly renowned for their Hesi nl bloom nutrients.

The Hesi nl bloom nutrients range consists of four main products:

· Hesi Bloom Complex – Formulated to address all of the extra needs of your plants during the flowering phase. This enriched formula has built in pH balance and no extra ballast, meaning every single drop is absorbed by your plants.
· Hesi Phosphorus-Plus – Designed to be used in conjunction with Hesi Bloom Complex, this phosphorus and potassium rich nutrient should be added during the second half of the flowering phase as your plants’ nutrient needs increase.
· Hesi Hydro Bloom – This bloom nutrient is specifically designed for soilless systems to meet all of your plants’ increased requirements during flowering.
· Hesi PK13/14 - As with Hesi Phosphorus-Plus, except specifically designed for soilless systems. A phosphorus and potassium rich supplement for the second half of the flowering phase to be used in conjunction with Hesi Hydro Bloom. Dosage should be steadily increased towards the end of flowering to match your plants’ needs.

Altogether the range of Hesi nl bloom nutrients will cater to all of the extra requirements your plants have during flowering. This will ensure bigger and better blooms, higher yields and happier cannabis growers.

House & Garden

Now an internationally renowned nutrient company that distributes its products worldwide, House & Garden is a Dutch company that was originally founded by William Van de Zwaan, a horticulturalist who has spent his whole life in the horticulture industry, being born to a family of professional Dutch rose gardeners.

House & Garden are constantly developing and expanding; innovating new products and opening up new markets. One product line that has brought them particular success is their range of House Garden coco nutrients.

Coco has become very popular as a growing medium in hydroponic set-ups, but coco has specific requirements and, unless you are very experienced, it makes sense to use a nutrient range that is designed specifically with a coco substrate in mind.

House Garden coco nutrients do just that. Their coco A&B nutrients have been formulated with a very precise balance of nutrients and minerals. In particular, House Garden coco nutrients are lower in potassium than other nutrients. This is to take into account the slow release of potassium that comes with using a coco substrate.
As well as the full range of beneficial elements that you would expect with your base nutrients, House Garden coco nutrients contain Eddha-Fe (iron) to enable rapid uptake of nutrient elements, along with humic and fulvic acids to improve uptake and transportation of these elements.
House Garden coco nutrients are designed to match the specific demands of plants in a coco substrate and can provide them with a basic nutrient regime that exactly meets their needs.

The range of products from Humboldt Nutrients, for both hydro and soil, is extensive and comprehensive. Humboldt Nutrients pretty much cover all of the bases and have a product to meet any requirement you can think of, and some that you can’t.
For the very basics Humboldt Nutrients offer their Humboldt Mix. A soil mix that is 60-70% sphagnum peat moss from Canada mixed with perlite, dolomitic lime and yucca extract. The excellent aeration and water retentive qualities of this mix make a great basis to start off a quality grow.
As well as the complete range of grow and bloom fertilizers, boosters, soil conditioners, additives and sweeteners that Humboldt Nutrients make available, they also offer their White Widow Biological Inoculants. This Mycorrhizal product will ensure a vigorous and healthy root system that will feed your plants, helping produce robust plants and superior yields.

No Mercy nutrientsNo Mercy nutrients are from a range of products from Dutch company No Mercy that supply everything for the cannabis grower. Founded by marijuana aficionado Cees, and based on his almost 40 years experience of growing weed, No Mercy provide an extensive seedbank as well as all the No Mercy nutrients that you would expect.

One of the most renowned products in the No Mercy nutrients line is the GA special spray which is discussed elsewhere in these pages.

Another product that is well worth a mention is No Mercy CO2 Tabs. Many growers, particularly with smaller, domestic set-ups, are keen to use CO2, but unable or unwilling to go to the extra hassle and expense that can be involved. This is a shame because upping the CO2 intake of your plants can seriously and dramatically improve production. With No Mercy CO2 Tabs it is now possible for anybody to augment their plants’ CO2 uptake. Simply add the CO2 tabs to the plants’ water supply. That’s all there is to it. No Mercy even supply a CO2 tabs dosage machine to automatically add CO2 tabs to your reservoir at regular intervals.

Of course, as well as the seedbank and CO2 tabs, No Mercy supply a comprehensive range of nutrients that, unlike some nutrient and horticultural products, are specifically designed with the cannabis grower in mind. No Mercy nutrients include foliar feed, guano extract, bacterial products, potting soils and other growing media. You can also benefit from a wealth of information that comes from Cees’ unquestionable expertise in the field.
