Medpot Minstrel: Hydroponics Medical Marijuana

Dissolved Solids, Salts--No-fuss Pouch System

The acid-alkaline balance of your hydroponic solution is vitally important. Some growers take daily readings, others read their pH hourly. It helps if you have the money to set up a fully automated system.

With such a system if your pH goes out of range of the desirable numbers for marijuana (usually 5.5 to 5.8) a little valve opens and the system adds pH Up or pH Down, depending on the discrepancy. These products made by Advanced Nutrients are the best and most professional way to correct any pH imbalance.

You might have come across the abbreviations EC, TDS, CF, or PPM. EC stands for Electrical Conductivity, which is measured in miliSiemens per centimeter. It helps to have a good EC meter to measure the amount of dissolved solids in your hydroponic solution.

In my experience, my ladies prefer 0.7 to 1.5 mS during the vegetative cycle, and 1.0 to 2.0 mS during flowering. If you want to correct the reading upwards, add more nutrients to your reservoir—downwards, you have to add more water.

TDS stands for Total Dissolved Solids, and it is another way of measuring the same thing. A TDS meter measures in PPM, or parts per million. During the vegetative stage, under a blue spectrum bulb, your PPM should be 450 to 1000. During red-spectrum flowering, it should go up to be between 700 and 1000 ppm.

CF is short for Conductivity Factor, and it is the EC scale multiplied by ten. To find your Electrical Conductivity, you have to divide the CF scale by ten. So 7.0 to 15 CF would be just about right for vegetative, and 10 to 20 CF would be optimal for flowering, depending on the strains of marijuana you are growing.

If this is too much fiddling for you, consider switching to EPN SensiPro as your main hydroponic fertilizer. It’s billed as the world’s highest producing comprehensive hydroponics fertilizer, which is definitely a point in its favor. What sold me on it is its ease of use.

Consider this—instead of mixing and blending and measuring and fussing, all you have to do is open the foil pouches and pour SensiPro into your water. It’s a week by week, scientifically pre-measured and formulated plant food, that takes into account the changing needs of your plants during both the vegetative and flowering stages.

But don’t take my word for it. Talk to the experts at Advanced Nutrients Medical, and they’ll advise you on what you need, taking your individual situation into account.

I called them last week, and they told me how a product of theirs that I am already using, has multiple uses. I’ve been using Piranha to strengthen the roots of my ladies, by colonizing them with beneficial fungi (have your heard of trichoderma and mycorrhizal fungi?), that not only aid in nutrient absorption, but also help increase my plants’ resistance to various pests, pathogens, and stress.

It seems that if I had read the product description carefully enough, I would have found out that you can use Piranha as a foliar spray, to protect your plants against gray mold, mildew, Rhizoctania solani, Sclerotium rolfsii, Phythium, Sclerotinia homoeocarpa, and Fusarium.

These harmful fungi are a mouthful to pronounce, but they could be devastating to your crop. So I’ve included a spray regimen with Piranha into my future growing plans, alongside Scorpion Juice, Barricade, and Protector.

Furthermore, when Piranha is used in conjunction with its companion, Voodoo Juice, they act synergistically to put a protective barrier around you marijuana plants, that few if any pathogens can penetrate. They also help produce bigger and better buds, which is where the secret of our powerful medicine lies.

Protector is designed to fight and protect against powdery mildew, while Barricade uses its potassium silicate to inoculate my plants from the inside out. Scorpion Juice, another dual purpose product, can be added to the root zone or used as a foliar spray. It imparts Acquired Systemic Resistance (SAR) which is like a vaccination against most of the destructive pathogens that can attack marijuana plants.

Carbo Load Liquid also interacts with Piranha and Voodoo Juice to create a natural environment for your crops that has a fertility similar to that found in the richest outdoor soil. These products are backed by the Advanced Nutrients Medical money-back performance guarantee.

If you’re the kind of medpot grower who likes to show off, you might want to check out the Advanced Nutrients medicinal growers Forum. Some great shots posted recently of very impressive buds, all nourished by Sensi One Bloom. The camaraderie and linguistic acrobatics are cool!

Gotta see my specialist to make sure that the big C is truly in remission. Send a kind thought my way, and I’ll report as to results next week.
