The Dangers Of Co2 Generators

Co2 is a necessity for the indoor grower. Claims have been made of 20% to 60% increase in growth rate and harvest. Plants that receive Co2 have more resistance to pest and disease. Most growers are growing in there home with grow rooms right next to the bedrooms or in there basements.

When you ad a Co2 tank the risk is minimal, raising your ppm to 150o, which is within human tolerance. When you add a Co2 generator you are now burning gas to produce the Co2 and a by product of this is Carbon Monoxide. In a sealed room these gasses can build up.

Homemade generators can be very dangrous. Using fumes from a water heater or furnace just seems dumb. So does using a propane heater or lantern. They produce Carbon Monoxide which can be lethal. It takes about 5 hours of fresh air to reduce the levels of carbon monoxide in your blood to 1/2.

In the winter people are at a higher risk of Carbon Monoxide poisning. Furnices are being used after a year of sitting idle. We are spending a lot more time inside. If you are using a Co2 generator make sure you have carbon monoxide detectors around the house(one on each level).

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.

Spring Growing Problems

Soon old foes will soon be out of their winter refuge.

Creep and crawl they will, straight to your nice warm garden. Your garden being the most temperate climate, is prime for early infestation.

Keep an eye out for these intruders. It’s much easier to prevent an infestation rater than remove an invasive species.

I have sticky pads ready for the first catch of the year.

As a preventive maintenance you can spray your plants down with soapy water. A few drops of Ivory dish soap in a spray bottle filled with water is all you need.

Make sure to keep a clean grow room as bugs and other things can easily be overlooked under a pile of leaves left on the floor or some spilled dirt.

Do you want to grow more or better?

I’ll take better any day of the week.

Higher resin content, higher trichome production, higher THC levels and higher CBN levels all add up to better more potent medication.

Street grade marijuana will become a thing of the past. With today’s law reforms going on all over the states, breeders will be able to work openly with out the constraints of the past and produce new strains all the time.

We have healthier plants with faster growth and more vigorous seedling that have shorter flowering time or auto flowering, because of some hard working breeders.

What is to come from this little weed?

Keeping healthy plants.

What is a healthy plant?

My definition of a healthy plant is one that is growing at its optimal rate.

Growth cannot always be measured by height because a plant that stretches for light will grow tall but be weak. Rather, judge health by it’s over all appearance.

Healthy is: a nice bright green, thick, healthy leave, free of wilt and nutrient burn with new growth and close branch formation.

We all want our plants to grow big and strong with out any problems.

Less is more with water and fertilizers.

Co2 is hard to over do. Most people need more than they think.

Air circulation is very important. If the air doesn’t move over the surface of the leave then it is stifled in its ability to process Co2 into O2.

Take each grow on a day by day basis. If your a beginner or expert, problems can sneek up on you. Make sure your remedy is measured so you don’t end up with a new set of problems.

Everyone Thinks They Can Grow Medical Marijuana

Happy plants make happy people and happy people grow the best medicine.

So you think your ready to grow medical marijuana. Good for you.

If you have any background in gardening your plants will grow just fine.

But will they reach medical grade potency? That is up to you.

If your starting with good genetics, then your better off than most. Do you have the ideal environment to grow in?

Not everyone does, and that’s pretty important. A well thought out grow room can increase plant vigor and yield.

Controlling the humidity is important.

Without a properly sealed room humidity and other important aspects of growing like temperature and Co2 levels would be difficult to regulate.

With a proper grow room and a little bit of a green thumb you can say goodbye to buying meds forever.
