Growing Diary - Fertilizing Cannabis: Cheap 'Ecogen' versus the prestigious 'Adsense'

A member of the magazine's forum asked to check out a question that intrigues many of the cannabis growers: Are dedicated fertilizers with bloated names and a price tag of up to thousands of shekels justifying their inflated price - or is it even possible to grow quality cannabis as well as fertilizer in NISNUMX?

Cannabis growers in Israel and in general, do not enjoy seeing the amount they are required to pay for quality fertilizer to their beloved plant. While each average tomato tower is forced to separate from a small amount of 30 to only NIS 70 to provide its tomato bush full nutrition, cannabis growers are forced to pay a sum that sometimes even reaches 4 digits.

For example, the price of "Akogen, Which will rise to the cannabis tower 49 NIS for a bottle of 5 a liter, will be sufficient for the whole cycle. On the other hand,House & Garden(House & Garden) will cost NIS 1043 for several bottles of a liter of base fertilizer and additives. So is the fertilizer of the 'Datch Pro(Dutch Pro) that will cost NIS 1350 for a comprehensive series of 1 liter bottles. In short, the gap is huge.

These inconceivable prices put the Israeli growers in a serious dilemma: to invest more than NIS 1,000 in the purchase of a dedicated fertilizer set that is supposed to work precisely for cannabis plants, alongside additives with high-end packaging and fragmented branding, Other?

Amitus, friend Forum Magazine He decided to examine the subject himself, and conducted a home-grown experiment in which he grew several plants under identical conditions (as much as possible in a relatively simple domestic farming), except for one parameter: one group of plants receives the most common cheap fertilizer, 49 per liter in each nursery, and a second group of plants that receive the Canadian Advanced Nutrients, a brand that will appear In the tumor stores (Grew Shop) only, which promises much higher results and with a price accordingly: more than 2,000 NIS.

So what fertilizer has yielded in testing plants with more crop? Before we go to the results of the experiment, it is important to note that there were quite a few reservations about the experiment in the forum - reservations that led For a discussion that lasted many months With no less than 590 responses. Many of the responses are from growers who complain that this is not an accurate experiment, and that it does not include research terms and conditions, with the help of which an unequivocal result can be determined.

The growth system

Amitus used a growing space size 60x60x160 cm, the plants were grown in a growing platform composed of 60% soil, 20% perlite and 20% coconut in the 3 liter planters of Airfoot, along with LED lighting 280 watts.

The circulating in space was performed using two caliper fans, and a small vantaa was installed for air circulation. The tested species was BigbudXXL, considered a species Indica Dominant with yield above average, and as a water source he used reverse osmosis water - a process that filters the salts and metals found in tap water.

The flowers were weighed and then Drying process Amitus published the data:

The plant that used the cheapest Akogen produced Cannabis 60, when the plant that was using the much more expensive fertilizer of 'Advance' finally produced 76 grams. A total of 22% difference was found in favor of the more expensive dedicated fertilizer.

In terms of additional parameters such as visual visibility, influence, taste, aroma, burning nature, etc. - the tower testified that it was difficult to distinguish differences.

Before reaching conclusions, it is important to note that many surfers as stated rejected the results and the entire process itself. One of the respondents claimed that due to the multitude of methodological problems in the experiment, nothing could be understood. Another tower wrote that due to the fact that some plants suffered from a certain lack of nitrogen during the growth cycle, it is difficult to draw real insights from the test.

Another argument raised by another member of the forum referred to the need to examine the final ratio and dosage of all the elements in the two different irrigation solutions, and therefore "this experiment is for me and for anyone who thinks logically and understands how plants work improperly."

We asked Amos to share with us the reasons that led him to conduct this fascinating experiment, to hear from him about the problems that were in the middle of the road, his response to the arguments raised against the experiment and his personal conclusions at the end of the cycle.

So what made you actually start this experiment?

Uncertainty about Akogen. It was cheap fertilizer and even "too cheap." Some users supported it and some rejected it out of hand. I always recommend mineral fertilizer (a "chemical fertilizer" that comes immediately to plant) and so it was important for me to test it myself before recommending it specifically.

Were there any difficulties, irregularities, or omissions during the tumor cycle that could harm the experiment itself?

As far as fertilizer is concerned, everything runs smooth and green from the beginning of the cycle to its completion. In terms of the fertilization of acogen, there were shortfalls between weeks of 3-4 for bloom, which led me to increase from 2.5 / mL to 4 / mL for a week to solve those deficiencies. In general I would recommend that users of Akogen raise the dose in 0.5-1 ml / L. in transition to bloom.

What are your conclusions from the results you received?

The conclusions spoke in the final result test. Advance's crop was close to 22% more than the yield of the plants that were fertilized with acogen. In terms of taste, smell, density, etc. - there is no difference, which means that the issue of Advance's additives must be checked again. However, at the beginning of the flowering, we could see increased fertilizer fertilization with Advance, which I think is also the reason for the differences in the final yield.

What are your answers to those who expressed such vigorous opposition both to the procedure and to its results?

It is legitimate. Apparently the opponents are not part of the group who asked the questions that caused me to start the examination. A winning horse does not change and it depends mainly on the tower - so that the tower that everything goes well with fertilizer company X, it will be easier to be critical towards any inspection to Fertilizer Company Y.

This is said - taste and smell. Most importantly, those who needed these conclusions accepted them - both objectively, both transparently and professionally - that the Israeli (illegal) domestic tower has to offer.

What would you recommend to Israeli growers - Akogen or a dedicated and expensive fertilizer?

I always recommend mineral fertilizers to Israeli growers. Beginners will definitely recommend Acogen and more advanced users. The obvious advantage that Edwards has over other fertilizer companies is that its base fertilizers and almost all additives include acid stabilizers. On the inside of the product you can see PH Perfect, which also works well in hydroponic systems.

Anything else you'd like to note?

In Israeli waters, there is one thing in common - lacking essential micro-elements. My secret to good, healthy and successful growth comes from a proper irrigation system and a combination of a dedicated calcium-magnesium supplement (calcium and magnesium deficiency that is lacking in water in Israel) in every irrigation.
