Nutrients For Medical Marijuana

 

Nitrogen, Phosphorus, and Potassium. 

These 3 ingredients are usually listed on the front label of the plant food in the order of N-P-K. A 20-20-20-plant food has a Nitrogen level of 20%.

Secondary nutrients are Calcium, Sulfur and Magnesium. In trace quantities, boron, copper, zinc, iron, and manganese.

Different nutrients are needed at different times. For rooting and germination, levels of high P nutrients with less N/K are needed. Vegetative growth needs lots of N a complete 20-20-20 with trace elements should do it. Watch for calcium, magnesium, sulfur and iron levels too. These are important. One tablespoon of dolomite or hydrated lime is used per gallon of growing medium. It is possible with passive hydroponics, to get nutrient build-up over several feedings, to the point the medium is over saturated in nutrients. Just feed straight water now and again, until you notice the plants are not as green (slightly), and then resume normal feeding.

Use weaker plant food mixtures than normal, maybe 25%, and be sure your leaching once a month and running straight water through the plants at least every other time you water. This applies mainly to plants grown in soil mediums.

Use of light strength Oxygen Plus plant food (or Food Grade Hydrogen Peroxide) allows the roots to breath better and prevents problems with over-watering. Check soil to be sure there are no PH anomalies that might be due to Hydrogen Peroxide in the solution. (Be sure your medium has good drainage. At this point, if your watering soil based plants once a week, you can water every 3-5 days instead if you plant them in a medium with better drainage. Pearlite or lava rock will greatly increase the drainage of the medium and make watering necessary more often. This will pump the plants; they will tend to grow faster because of the enhanced oxygen to the roots. Make sure the plant medium is almost dry before watering again, as the plant grows faster this way.

Stop all plant food 2 weeks before harvesting, so that the plants do not taste like plant food. (This applies to hydroponics as well.)

WARNING: Do not over-fertilize. Always read the instructions for the fertilizer being used. Use 1/2 strength if adding to the water for all feedings in soil or hydroponics if you are unsure of what your plants can take. Build up slowly to higher concentrations of food over time. Novice soil growers tend to over-fertilize their plants. Mineral salts build up over time to higher levels of dissolved solids. Use straight water for one feeding in hydroponics if it is believed the buildup is getting too great. Leach plants in pots every month. If your plants look REALLY green, withhold food for a while to be sure they are not being over-fed.

Keep Your Grow Room Cool

The least expensive way of reducing the heat in the grow room is to vent out the heat and replace it with cooler air.

Sounds simple right? Well it is, but what most beginners forget is that you can’t blow the hot air out without a way for the cool air to get in to replace it. The best way to setup a venting system like this is to mount one exhaust blower on the inside of the grow room up high to blow the heat out, and another blower on the outside mounted down low blowing cool air in. Hot air rises, cool air settles.

The exhaust blower can be turned on with a thermostat so it only runs if the temperature gets too high. The thermostats plug into the wall and have an outlet for the blower. When you set the temperature at, let’s say 80 degrees, the blower will turn on at 80 degrees. It will stay on until the temperature drops to 80 minus the differential. The differential is the difference between the turn on point and the turn off point. It’s usually about 4 degrees. This means that if the thermostat is set at 80, the blower will turn on at 80 degrees and turn off at 76 degrees. This gives the blower some working time. If the thermostat had no differential the blower would turn off as soon as it turns on, then off, then on, etc., not very efficient.

Some people turn the blowers on with a timer. The blower might be set to turn on at a specific time or multiple times during the day. This will also get the job done, but it’s not the most efficient method. If you’re looking to control the temperature you should measure the temperature, not the time of day.

Sometimes the air coming in is just too hot and can’t cool the room. When this is the case the blower can be run on the same timer as the grow light, or another timer set to go on at the same time. This is not really solving the problem, just a cheap fix. The problem is the air coming in is too hot, so why not cool it. An air conditioner can be used for the supply air and a blower can blow out the heat.

Air Cooled ReflectorAn alternative to moving all the air out is to capture the heated air and vent it. This can be done with an air cooled grow light. The advantage with this setup is that you’re using less energy to move the heat out. The volume of air in the reflector might be 3 cubic feet and you can vent it out in a few seconds. It doesn’t matter if it’s hotter, just how much of it you have to move. Venting a 288 cubic foot grow room that’s 95 degrees takes a lot longer than venting a 3 cubic foot reflector that’s 150 degrees.

Keeping Your Grow-Op Safe

Show no one! That is the first line of defense.

Once you show your grow op to someone they will tell some one else.

That’s a fact.

People want to feel important so in the middle of a conversation things slip that normally wouldn’t or shouldn’t.For this reason alone keep it zipped.

Now there is an exception to every rule.

You may require the help of a consultant if your having a problem with your grow. If your new to growing and your serious about your medication then having someone who can diagnose your plants and teach you about growing will be invaluable.

Keep the number of people who know your growing to a minimum and where your growing at top secret.
