Hello,
I really really love the GH three part. I love it in soil and I love it in hydro. It is called GH Flora Series and has three parts: Flora Micro, Flora Bloom, and Flora grow. There are nutrient calculators on the GH website and as an iphone app. You input your reservoir size and it tells you how much to mix in of each.
I really love growing in straight hydroton rocks. I have a couple of 3X3 ebb and flow tables.. Each of them can veg 16 clones to about a foot.
Then i transfer into my DIY ebb monster bucket system. It is basically a five gallon bucket withing a five gallon bucket. There are 18 of them plumbed to a 55 gallon drum.
Every few hours the buckets fill and drain. The plants go from one foot to being 4-5 monsters with no additional vegging once i throw them into the buckets.
the system looks like this:
I have not used lava sand or zeolite.. Unless zeolite is diatomaceous earth... is it? made up of ancient arthropod shells?
OK, so in the beginnging there was only rock on this planet. tiny plants grew on it and becan to break it down. The rocks also broke down to physical weathering. All of the minerals in TODAYS soil was once a big rock. Through the plants breaking down this rock into smaller bits (clay, silt, sand) and combining their root juices and enzymes with it, soil began to form. Bigger lichens formed and then woodier plants. All the while breaking down minerals into the soil. Eventually microbes and fungi came along and helped this happen even more. They grew IN ON AND AROUND plant roots, becoming part of the plants and vital to organics.
Hydroponics feeds the plants the minerals it needs without all of the additives. YES I KNOW that they are popular, but hydro was originally sterile and works best that way for ease of use. Adding organics adds a level of complexity that is confusing for beginners. I have had TREMENDOUS success following the GH nutrient feeding schedule in both SOIL and HYDRO.
You can totaly use the GH on your soil grow. They offer instructions called "drain to waste" which is what you do in containers that drip out the bottom.
In soil, tho, you have a medium that is not inert like my clay balls. Soil has living things and components that affect pH, solubility of nutrients, etc. that all work into the equation...
Seaweed is still a good additive, molasses is good to feed root zone microbe life. Fish emulsion is stinky for hydro, but great for dirt. Epsom salt is magnesium, which is in any complete hydro nutrient... I don't know about greensand.. Manure is for your soil life o break down and feed to your plants' roots...
I love both soil and hydro. I at first tried to make my hydro like my soil. I am getting away from that..
Right now I have plants in both dirt and hydro.. I'd like to snap some pics for people that talk shit about either method. they both work well BUT require different mindsets.
