Now that you’ve selected a growing medium, it’s time to choose which type of hydroponic setup to use. All systems are similar in that they utilise a nutrient-enriched water solution. However, setups can vary widely depending on factors such as water exposure and circulation. Most of the following systems can be purchased, but those with DIY skills could easily make them by using buckets, drills, pumps, and air stones.
Hydroponic cultivation might initially seem like the result of modern advances in technology. But this couldn’t be further from the truth. The origins of growing plants in water goes back thousands of years into human history. The famous Hanging Gardens of Babylon, created in 600 BCE, are theorised to have utilised hydroponic principles. The region located next to the Euphrates was naturally dry and arid. It’s believed the crops of the garden were nurtured using a trickle-system starting at the river.
Hydroponic cannabis has an ideal temperature of 20°C. This factor can be monitored using a water thermometer and altered using a water heater if the temperatures are too low.
Deep Water Culture
Hydroponics is a method of cultivating plants, specifically cannabis in this case, in a solution of water and nutrients.
Both growing trays and tanks require emptying and cleaning around every two weeks. This process will keep the roots of your plants safe against invading pathogens and diseases. Repeat the same process mentioned above when initially preparing your system.
Every hydroponic system requires frequent maintenance to provide an optimal growing environment. Below are all of the major factors you need to be aware of.
White Widow is a perfectly balanced hybrid strain that features 50% indica genetics and 50% sativa genetics. She was created using parent strain White Widow S1, and provides a well-balanced high that stimulates and excites the mind whilst relaxing and stoning the body. A THC level of 19% ensures a powerful psychoactive experience that lasts several hours. These flowers contain a terpene profile that emanates grounding tastes and smells of earth and pine.
5.) Install Rapid Rooter and water the seedlings until roots reach the water reservoir – Turn on light to keep seedlings warm for best results!
If there’s no germination at all…

If you haven’t put your hydroponic system together yet, now is the time! Make sure your pumps are all running, and that you’ve made a reservoir with seedling-strength nutrients. You need a home to put your new plants!
Just like in soil or coco, cannabis plants in hydro grow fastest when it’s a little warm, around 75°F!
Seeds are the result of pollination. That means the seedy cannabis buds (which come from a female plant) may have come into contact with pollen from a male plant. Therefore, it’s possible the grower didn’t identify and remove all the male plants before the released pollen. It’s also possible that the plant self-pollinated (sometimes called herming) which is often the result of plant stress during the budding phase but can also be caused by genetics.
What does it mean to find seeds in your marijuana buds? Is it something to be worried about?
Finding a hermaphrodite in your growroom can happen at any stage of the flowering cycle and is indicated by the presence of male flowers growing on the same plant as female flowers. As with all species in nature this can occur in varying degrees. A plant can become slightly or majorly hermaphroditic. In cases where singular male flowers are found between the branch and stalk nodes, you should be diligently removing them as they grow. You must re-inspect the plant top to bottom every few days to be sure pollination and seeding doesn’t occur. If you find male flowers (anthers) actually growing from within the female flowers (buds) the situation is a little more dire. You can still remove all the male anatomy as it appears, but it will be harder to find and much more prevalent. This is a horrible discovery that leads to a tough decision: Should you let the plant live and risk the whole crop being ruined by seeds?
Light poisoning is the most common cause for a normal plant to hermaphrodite. Light poisoning refers to the flowering night cycle of a plant being unnaturally interrupted with light. The best way to prevent this is to close yourself inside your darkened room during the daylight, and then after allowing a few minutes for your eyes to adjust to the dark, check for any light leaks from covered windows, door jams, etc. Also cover all timer and appliance lights with tape.

It should be dark and relatively hard. Very pale or white seeds, that can be easily crushed between the fingers, usually won’t sprout. However, I have been surprised to find some very flimsy seeds sprout and produce amazing plants (we aren’t breeding them for hard seeds after all) so when in doubt, I highly recommend doing the true test to see if the seed is viable – try to germinate the seed and see if it sprouts!
In either case, once hermaphroditism has compromised the safety and purity of your sensimilla, the plant should not be propagated further. Remember, once a hermy, always a hermy. The plant pictured here is in the tenth and what should have been the final week of ripening, but a timer failed and one light stayed on continuously for almost two weeks, causing this vegetative regrowth. Because the light was continuous, the plant made no pollen. This method of re-vegging can be used to save a flowering plant you have no copies of, but be careful, as this may cause some strains to hermaphrodite.
Cannabis plants are monecious. This means they have the ability to be either male or female. Or in the case of hermaphroditism, they can be both. The reason to make sure there are no males or hermaphrodites in your garden is because male flowers make pollen. When pollen touches the white hairs on a flower, it makes a seed, and seeded weed gives you headaches. Even though there are reasons in nature hermaphroditism could be important, such as continuing the species in case there is no male present, hermaphroditism is generally a bad thing when talking about cannabis plants.
