Nutrient FAQ

Organic or chemical?

Before you even start looking at all the available products, you must answer the question: Am I going hydro, organic, or chemical with the nutes? You will find that hydroponic and soil based nutrients come in both chemical, organic and organic based varieties. Some nutrients are hydroponic exclusive while others are intended for soil applications only. Many nutes can be used in both soil and hydroponic grows.

Should I stick with one brand?

Many growers opt to stick with one line of nutrients from one single manufacturer. The reasoning is very simple: they are meant to work in conjunction with one another. The nute manufacturers develop their products in a manner that, in theory, is suppose to provide your beloved plants with the optimal results.

What makes some brands of  nutrients bad choices for cannabis?

Simply, some brands are just not intended for this type of application. Just like cacti, orchids, tomatoes, blueberries, etc have specifically formulated fertilizers, the same is true for cannabis.

Will cheap all-purpose brands of fertilizers work?

The short answer, yes. The long answer, not really. Again, we want to grow healthy plants. To do this specific things need to be considered. By going with something that cost a few bucks more, you may save yourself a lot of headache a few weeks into the grow.

What is N-P-K (NPK)?

The three primary plant nutrients are nitrogen(N), phosphate (P) and potassium/potash (K). NPK numbers are required by law to be printed on all fertilizer bags/bottles.

What are macronutrients?

Essential elements used by plants in relatively large amounts for plant growth are called macronutrients. The major macronutrients are nitrogen (N), phosphorous (P), and potassium (K). Calcium (Ca), magnesium (Mg), and sulfur (S).  Some suggest that only NPK should be in this category and the rest should be considered micronutrients.

What are micronutrients?

Micronutrients are elements essential for plant growth which are needed in only very small  quantities . These elements are sometimes called minor elements or trace elements. The micronutrients are boron (B), copper (Cu), Iron (Fe), chloride (Cl), magnesium (Mn), molybdenum (Mo), and zinc (Zn).

What is the difference between granular and liquid fertilizers?

Granular fertilizers are often time released and are only suitable for guerrilla operations in which the grower cannot visit very often. Liquid fertilizers are fast acting and are immediately available to the plant(s).

What is a soiless planting mix?

A soiless planting mix may look like soil, but its not. Often it contains sphagnum peat moss, perlite, compost, manure, etc. As you can see, none of that is soil.

What are additives and supplements?

What is pH up and pH down?

Both pH up and pH down are used in hydroponic grows (and sometimes soil) to adjust the pH level of the water.

Why should I go with organic nutrients?

Many people say that their bud just taste better when going this route. Thats the main reason for many growers. Still, many find it better to go with what mother nature has provided as opposed to what is produced by chemical companies. Its the green way to go!

MG logo Not the best choice for growing cannabis. The granular fertilizer is fair for guerrilla grows. Chemical, unless stated otherwise. Intended for soil grows. I'm not going to waste time on MG products.

shultz logo Not the best choice for growing cannabis. Chemical, unless stated otherwise. Meant for soil applications. Personally I think its a better choice than Miracle-Gro, but still not what is needed to sustain healthy pot plants. Their Cacti Plus fertilizer is great though.

osmocote logoOsmocote seems to be a good choice for the budget soil grower. The reasoning is simple: availability. I like this stuff for vegetable gardening. The time release fert is perfect for guerrilla grows. Chemical and meant for soil.

OMRI (Organic Materials Review Institute) is a proud label that goes to products that have proven to be 100% organic. Do not by organic products unless it has this label.

Hydro for Hunger is an initiative by participating independent hydroponic merchants in support of hunger relief organizations including the Institute for Simplified Hydroponics (ISH). ISH is a non-profit organization dedicated to reducing world hunger through the power of hydroponic gardening. Using interactive Internet-based training programs ISH helps provide people in developing countries with the knowledge and tools to become self-sufficient through simple, small scale hydroponic food production techniques.

 Description from hydroforhunger.com. Its a good cause and worth a couple extra bucks.
