Solo cup grow: Why is it hard?
Growing cannabis in a cup is an amusing venture, but there are a few challenges to this technique. Here are some of the difficulties you may encounter when embarking on this mini-adventure:
- Roots need space to grow and may get constricted in the small base of the cup.
- As the plants expand, it can be challenging to water them adequately to ensure enough fluid reaches the roots.
- Growing in potentially suffocating conditions, you have to create the optimal climate as they’re more prone to mold, dehydration, and diseases.
- As the plants get bigger and heavier, balancing them is challenging because the cups aren’t as stable as pots. This issue may cause plants to fall over.
- New strains of weed that aren’t hardy or have ruderalis genetics won’t survive growing in a cup.
Advantages of growing weed in a cup
Why would anyone want to grow cannabis in a cup? Here are the benefits of growing cannabis in a cup:
- Cups provide excellent insulation for marijuana plants, especially during their early stages when they’re hungry. Following the weed fertilizers steps, the cup locks the water and nutrients in so the roots can take what they need.
- Perforating holes in a cup is easy and practical. The tiny craters are ideal for excellent drainage while preventing excessive fluid loss.
- If you have limited space, a solo cup cannabis growing method helps you cultivate plants that fit anywhere from your bedside to a windowsill.
- Plastic cups are probably the cheapest container to grow cannabis seeds in.
- With a clear plastic cup, you can easily see the entirety of your plant, including the roots. By monitoring this, you’ll be able to spot root rot or other issues before they manifest on the entire plant.
- If you need to suddenly hide your plants (perhaps a surprise visit from the in-laws), transferring them to a secret space is easy.
- Solo cup weed plants are easy to transfer. Simply cut the plastic cup and move the plant to another grow medium or container.
Disadvantages of a Solo cup grow
Solo cup cannabis growing has its downside too. Here are some disadvantages of putting marijuana plants in cups:
- Stunted growth due to lack of space for roots to expand
- Some cups are made from harsh chemicals which could degrade and damage your plants. Eco-friendly or biodegradable ones typically don’t have this effect.
- During flowering, your plants become thirsty, so you’ll need to water them frequently, which may prove difficult while they’re in cups.
Solo cup weed grow method: step by step
Are you ready to start growing weed in a cup? You only need to gather your cannabis seeds, a plastic cup, some soil, and a pair of scissors. Here are the steps to planting this mini marijuana masterpiece:
Step 1: Cannabis seeds germination
Germinating is the first step in growing marijuana seeds, regardless of which medium, method, or container you plan on using. Also known as popping, this step involves sprouting your seeds, so they’re ready to be planted in the soil.
The best way to germinate before growing cannabis in a cup is using the paper towel method. Gather a plate, two paper towels, and some water and follow these steps:
- Dampen the paper towels and place one onto the plate.
- Put the cannabis seeds onto the paper towel, ensuring they’re at least one inch apart.
- Cover with the remaining paper towel. Check that there’s no water pooling on the plate.
- Store in a warm place and look out for taproots which take between 1–5 days to sprout.
Step 2: Planting in a cup
Once taproots appear, they’re ready for you to plant them. Before you get started, poke a few holes at the bottom of the cup to create sufficient drainage.
Seedlings are hungry and need excellent nutrition to help them grow fast and strong. Add a potting mix or organic nutrient solution to your soil so your marijuana seeds get enough nutrients.
When starting your solo cup grow project, remember that seedlings are fragile, so handle them carefully. While transplanting cannabis sprouts from the paper plate to the soil, it’s advisable to use tweezers or earbuds to prevent accidents.
Step 3: Take care of the cannabis plant
The only difference with a solo cup weed grow is the roots won’t have much room to expand, giving you smaller than usual plants. If you know how to harvest cannabis, you’ll notice your yields are less than expected with cup growing.
As your marijuana seeds grow, feed them sufficient nutrients and water. If you’re placing these on a windowsill, they can become easily dehydrated, so check that the soil is always moist. The cluttered roots may require a lot of water, especially during the early stages.
If you’re nurturing a large cultivar, you should train your plants so they don’t get too big. Pruning is essential, so they don’t lose sufficient nutrition. Take care of your flora daily, as growing weed in a cup makes them vulnerable to deficiencies and lockout.
