When can my cuttings in the sun or under lamps?

When the cuttings have created a third branch, they are strong enough to stand under grow lights or under sunlight. With grow lights, keep in mind that you keep the right distance between the lamp and your cannabis plants.

How do I know when I can harvest?

When the hairs of the buds have turned brown to 75% during the flowering phase, the plant is ready to be harvested. This is not the only way to know when exactly your plant is ready to be harvested. You can also view the color of the trichomes under a microscope to determine when the right time is there.

Can I just give my plant (s) tap water?

This is possible, but the pH value of tap water is often very high and must be adjusted with pH to a value that is pleasant for our plants. This is between 6.0 and 6.3 for soil and about 5.8 when using hydro. To be able to adjust the correct values you will first have to purchase a pH meter.

What is my yield?

Of course this is very different per situation and therefore difficult to say. With an outdoor grow this can vary from 1 to 500 grams. This depends very much on nature. When growing cannabis indoors, we always calculate the watts in grams. For a beginner, this will be 0.4 to 0.7 x the number of watts. With an advanced this can go up to grams per watt.

How much water should I give?

Keep the soil moist but not too wet. A cannabis plant likes an airy soil and will drown if the soil remains too wet. You can also purchase a tensiometer to measure the soil precisely.
