The greatest advantage associated with cannabis is it’s 100 % natural healing and medicinal powers.
So, from my perspective, it is obvious that gardeners should definitely use organic soil as the growing medium. Why would you take something purely organic and ruin it with chemicals? It simply makes no sense.
Is it a little more profitable to use hydro as an alternative to soil?
No, it’s not. You have to focus on the big picture. Besides the high cost of chemical-based nutrients for hydroponic marijuana cultivation, using (smoking, vaping, cooking with) the harvest from chemically produced plants puts those chemicals in your body, and will increase your medical bills in the future. So, if it takes an extra week to finish your marijuana buds in a soil medium, the added electricity expense for that extra few days will be less than your medical bills and overall health in the future. Far more important than prospective medical bills, is the way in which you feel every day existing chemically f-r-e-e, with much more energy, increased productivity and just the all around experience of being healthy. That in itself is invaluable.
Therefore, if it costs you an extra $5-10 per harvest in the short run, it’s resources smartly invested. Besides, medical Marijuana patients, and customers too, will be demanding pure organic marijuana, and providers will be required to transition to meet demand. It is elementary economics.
With that said, lets move on to what you are really interested in — the way to get considerably more females to develop from your 10 pack of marijuana seeds you paid good money for.
What you need to know about cultivating marijuana is that the overall experience of the grower has a lot to do with the male to female ratio when growing from seed. You can give 5 various gardeners the same 10 seeds, and they will all have totally different results. Some growers will have no females while others can have 50% or more. The sex is not exactly predetermined before the grower gets the seeds. It’s all about a knowing few advanced tips and most crucial, reducing stress on the marijuana plants, specifically right before the calyxes begin to form.
Look at controlling stress levels when germinating and growing marijuana – Just like you’d watch your loved one’s blood sugar levels if they are diabetic. The less a diabetic’s sugar levels fluctuate, the less stress they will experience.
So it goes with cultivating marijuana.
If you over-water or allow your plants’ soil to completely dry out, it WILL cause stress, just the same as when a diabetic eats foods with too much sugar or injects too much insulin – their sugar levels will fluctuate causing stress and illness.
To grow stress-free marijuana and get a higher female to male plant ratio, make sure that:
1. Soil moisture levels to not become over watered or dried out.
2. You keep the nutrients feeding regulated, not spiking or depleting the amounts of nutrients throughout each day. An equal ratio N,K and P will have reasonable results obtaining female plants.
3. Room temperature will not fluctuate excessively
4. Room humidity levels don’t fluctuate too much
5. Never use 24 hours of light for vegetation, 18 on / 6 off is suitable, but not optimal for growing more females. Read below for more advanced techniques.
6. Keep the plants’ light cycles precise, and never permit light pollution (not even for a second) to get in touch with your plants during its dark cycle.
If you maintain all of the above recommendations, you should have 60-70% females. If you want to achieve 70-100% female plants from seeds, read the following advanced tips:
Use more Nitrogen; you get more females when you have a bit more Nitrogen and less Potassium. If your Potassium levels are higher, you will get more male plants. A tad bit more Nitrogen is more beneficial for the vegetation cycle anyway.
Ensure your humidity levels are high right from seed with a humidity dome. If humidity levels are low, you are certain to get more males. Also keep your soil from drying, this will result in more males.
Environment does have a little to do with the strain background. Unless you’re growing a tropical strain, such as a Sativa from Thailand that loves the temperature up around 85 degrees, always try to keep the temperature lower. High heat creates stress on the majority of the marijuana strains, and it results in more males. Keep your room temperature as close to 70 degrees Fahrenheit as possible, and make sure it does not decrease by more than 5 degrees when the lights are out, or you will create more males.
Keeping the relative humidity of the room at 70% is the best for females to form. Humidity over 80 and under 60 will result in more males.
Do not top your plants or take clones before sex is shown. This can contribute stress and develop more males.
Utilize a Metal Halide (MH) during vegetation and a High Pressure Sodium Bulb (HPS) for flowering. This will create more females.
Before you change the light cycle from vegetation to flowering, be sure your plants are stress free. If you recently over fertilized, or treated the soil for mold or plant for pests, wait a few days for the plants to overcome any stress, then go into the flowering cycle, even if it throws your schedule off by a few days, it is usually well worth it as you may get 20% more females purely by waiting the extra 3 days for them to recover from the stress.
You’ll find it also ideal to vegetate under 14.5 hours of light for optimum female ratios. If this cannot be practiced, then use 16. And if you’re still in too much of a hurry, use 18, but never 24 hours of light or you will have too many males.
You get a lot more females using 14.5 hour of light during the vegetative cycle, slightly less using 16, slightly less at 18, but your chances dramatically decrease if you use 24 hours of light. You could end up with 70% male up, or even up to 100% male plants. You could actually get NO FEMALES AT ALL. It’s not worth the risk, especially if you happen to be cultivating higher end strains.
