1. Don't overwater
Overwatering kills marijuana plants. Water once the top few inches of the soil dry out. Hydroponics is harder to over water because rockwool has such excellent drainage properties. As long as the rockwool cubes are not sitting in liquid it is virtually impossible to over water a hydroponic setup. A hydroponic setup could either be watered constantly as the drip method, or once to three times a day as in the flood and drain method.
2. Don't tell people
Why? They will only be jealous. People love to feel important and that is why they will tell other people; because others will listen to them. " Keep it to yourself ".
3. Touch/kill germinating seeds
Please have some patience. It sometimes takes 10 days for a marijuana seed to sprout. The paper towel method is not recommended because you must handle the marijuana seeds when transferring them from the paper towel to your growing medium. Proper marijuana germination »
4. Grow seeds from seeded marijuana
One of the greatest disappointments known to the growing man. 90% of what the final product will be is in the cannabis seed's genetics and has little to do with the environment the marijuana plant is grown in. Many get their hands on the marijuana seed and think they have a gold mine. They will probably grow something like this: hermaphrodites, tall late flowering female marijuana plants coupled with early flowering male marijuana plants. This is because the only pollen that could have produced the marijuana seed was from a hermaphrodite or a very stunted and late flowering male the marijuana grower did not notice. Unless you are prepared for possible disappointment don't use "unknown" marijuana seeds. This is why people buy marijuana seeds from seedbanks.
5. Don't over fertilize
Fertilize after first 2 spiked leaves appear follow the label. DON'T FERTILIZE EVERY TIME YOU WATER! Start with 25% and work your way up! Leach the marijuana plants with lots of pure water every 2 to 4 weeks. Organic growing is recommended. It's tastes better and burns much better. If the leaves suddenly twist or fold under, Leach and Spray with pure water for several days!
6. Don't under fertilize
Under fertilizing is less common but it happens. If you are one of those people that likes to give the marijuana plant just enough nutrients make sure you use a organic soil mixture with blood meal and bone meal or some slow release fertilizer with micro nutrients.
7. Don't start with clones
Start with marijuana seeds. Bugs are a pain, So are marijuana plant diseases. Many marijuana growers are able to grow indoors without pest problems for years. If they do get pests they are probably not enjoying the change from their usual diet to marijuana resin! But as soon as you come in contact with others grow material [cuttings] it is almost guaranteed that its from a long time marijuana grower that has many different pests all eating marijuana and bug spray [and surviving] for hundreds of generations!... Think about it.
8. Don't start too early inside or outdoors
For several reasons! If you are starting outdoors June the 1st is perfect. Question: But if I start earlier I will get bigger marijuana buds right? Answer: Probably Wrong! Its strange but usually true. We will explain. Marijuana plants started in early spring will get big but they will take significantly longer to start flowering. This is because at the peak vegetative period they sense the light cycles getting longer and longer, until June the 21st. But they don't realize that it's time to flower yet. Finally in the middle of August the marijuana plant says "HEY...time to flower already" and it produces marijuana buds in August and September or later they will be tall as trees but thinner marijuana buds due to the fact that the sun is not as strong in September.
Now if the marijuana plants were put out later, as soon as they get a foot | 30 cm off the ground they say "what's going on...I am just in early veggie and the light hours aren't getting longer in fact SHORTER" Then the cannabis plants go crazy and since the sun is so bright in July and August you get amazing 6 foot | 180 cm marijuana trees that are heavier than the marijuana plants started in April! In addition to finishing earlier the late started marijuana plants are not nearly as noticeable. Indoor marijuana growing is the same for different reasons. The light cannot penetrate more than a foot or two | 60 cm. So flower when marijuana plants are a foot | 30 cm tall. If you wait longer because you want bigger marijuana yields, you will get smaller yields and wait longer for them.
9. Don't provide a bad environment
Always provide air circulation and fresh air even during the night cycle is fine. All the air indoors should be replaced every 5 to 10 minutes. Humidity between 30 to 70% temperature aim for around 75°F to 85°F | 24°C to 29°C. Even marijuana seedlings need a gentle fan to strengthen the stems.
10. Don't harvest too early
We know it's hard. You see the marijuana buds and resin forming at a rapid rate. The buds are potent and you feel tempted to chop them down! The only problem is that another 25% of the weight will form in 2 more weeks. Wait until the marijuana plants have totally stopped growing and the white pistils are at least 50 to 75% brown.
