also coco=hydro its not soil you can treat in like soil but you get way better results if you treat it like hydro im on my 2 run in coco cheack out my grow in my sig

Coco: Extremely high CEC, gifted to coco by growing near sea water, allows Coco Coir and Coco Peat growing media to have great value as a hydroponic media. The coco retains high levels of calcium and potassium that act as a pH buffer, keeping the pH slightly acidic. The spongey structure of coco allows it to keep a large amount of air in the media even when saturated, which makes over watering a plant that has an established root system very difficult to do. Coco is inert but can be amended for organics and is especially effective in the relatively new area of hydro-organics as the structure of the coco also benefits the growth and housing of beneficial microbial and fungal life which will increase uptake.

Soil: Soil is a conglomeration of many things. Mostly it is a combination of clays (minerals), Sand/Silt (more minerals), and organic waste/compost. The ratio of these things to one another, and the maturity of the soil, play huge roles in the quality of soil. The same stuff 6 months older could have a far different quality given the continuing work of microbes in the soil. Soil will retain too much water indoors so it must be amended with a bit of aeration material like Perlite. Perlite will help retain moisture and air around the root zone and decrease the chances of root rot (an unwanted fungal infection kinda like athletes foot but for plants). Soil offers the plant a constant supply of nutrients which are broken down and then absorbed by root cells. The organic balance of soil is difficult for many new growers to understand. Thus, it is very important that a new grower who chooses to grow in soil understand the "rules" they need to follow to keep the soil healthy. Sick plants come from sick soil. The pH must never be too low in the solution or it will kill microbes. The grower cannot use nutrients that contain EDTA as a chelating agent as this will weaken the microbes cell walls causing them to die off. The soil can never go bone dry, and never stay completely saturated for too long, as both scenarios will deprive them of something they need be it moisture or oxygen.

So, with coco you can still maintain a healthy organic system as you can in soil. Coco also offers hydroponic growth rates which does put soil to shame. Soil will wind up growing the tastiest buds though, and for the connoisseur home grower soil is really the best direction. Ultimately though, coco is an easier media to grow with as it develops a pH buffer and reduces long term costs. I always say that if a person can mix up a batch of pancakes then they have the skills required for coco. It is important to watch nutrient levels in coco, and I keep a good Magnesium supplement (not from Epsom Salt as the Sulfur will interfere with the Calcium buffer and impede Phosphate absorption) because the presence of Ca+2 and K+1 will compete with Mg+2 for electrical absorption. The Calcium and Potassium have a "foot hold" in the media but Magnesium will need to be supplemented at some point to combat flowering nutrient changes.

Personally I'll never grow without coco. I think a good mix would be 30% coco, 30% Soil, 20% Perlite, 10% organic amendments. A best of both worlds situation.

excellent post snow!! if i make a super coco, how infrequently do you think i can feed? with my super soil, my plants only need feeding once a month
