How to grow feminized seeds indoors

Do you want to know how to grow feminized seeds indoors? These tips from Dutch Passion will help you grow the best feminized seeds indoors. More information can be found in our extensive indoor growing guide.

Choose a grow system that you can understand

Deep water culture may be one of the best ways to grow feminized seeds indoors, but it requires a good working knowledge of nutrient management, nutrient measurement and plenty of experience. Growing cannabis in coco fibre is easier and produces heavy crops. Many first time cannabis growers start growing with a soil mix bought from the local grow shop. Once you have grown a few crops your confidence will improve and you will understand the basics, and feel able to tackle more complicated grow systems. Keep your first cannabis grows as simple as you can, and use the local grow shop for advice. Your local hydroponics store is a one-stop shop for materials and advice. 

Choosing feminized seeds for indoor growing

It’s never been easier to buy feminized seeds online. Although you have hundreds of varieties to choose from, your first decision is whether to buy feminized autoflower seeds or feminized photoperiod seeds.  

Growing feminized autoflower seeds indoors

Feminized autoflower seeds grow from seed to harvest with 20 hours of daily light, taking around 75 days. First time cannabis growers are often recommended to grow feminized autoflower seeds, they are easy to grow and the best autoflower seeds can produce huge yields of several hundred grams per plant in good conditions. The Dutch Passion feminized autoflower seed collection is one of the best available, with lots of customer grow reviews.

Growing feminized photoperiod seeds indoors

Feminized photoperiod seeds are often simply called feminized seeds. They have two growth phases controlled by the amount of light. When growing feminized seeds indoors under 18+ hours of daily light they grow in a vegetive mode, producing leaves, roots, branches but no buds. When the amount of daily light is reduced to 12 hours the plants start to produce buds, this is known as the bloom phase, sometimes called the flowering phase. Depending on the variety, the bloom phase takes around 9 weeks of 12/12 light. One of the best tips for growing feminized seeds indoors is to provide plenty of light during bloom to maximise your harvest. For a 1.2 x 1.2m tent a 600W HPS is a good solution, and some growers will use higher light levels to maximise their harvest.

Feminized seeds indoors. Avoid over-feeding and over-watering

When growing feminized seeds indoors the two main mistakes we see are plants being over fed, and (for soil grown plants) over-watering is a common error. Cannabis roots need oxygen to thrive, they don’t like waterlogged soil. Allow the soil to partially dry out between waterings, this allows some root aeration. Over feeding plants can really slow down development, the tips of the leaves go brown and crispy – a condition known as nutrient burn. Experienced growers monitor their nutrient concentrations using an EC meter to measure Electrical Conductivity, they are a recommended grow room gadget to help optimise your grows. Over-feeding your cannabis plants is particularly damaging to young plants which can remain permanently stunted, never fully recovering afterwards. When growing feminized seeds indoors, start your plants at low nutrient concentrations and gradually increase nutrient concentration, backing off at the first sign of over feeding.

Feminized seeds indoors. Maintaining the nutrient sweet spot

The experienced cannabis grower is able to steadily increase nutrient concentrations throughout the grow without under-feeding or over-feeding his plants. Keeping your plants in this nutrient sweet spot will ensure that you feminized seeds grow into healthy, heavy yielding plants. If light levels are high, the root mass is healthy and plenty of fresh air is supplied to the grow room then you should get healthy plants with heavy blooms.

The best nutrients for feminized seed indoor growing

All of the major nutrient companies offer products that will grow good quality cannabis. Many growers will eventually settle on their own preferred nutrient brand and feel that using the same brand with increased skill and experience is the best approach.

High THC results with feminized seeds grown indoors

Combine good quality cannabis genetics with an optimised environment and you will get heavy harvests of THC rich buds. The latest research is showing that crops grown under high intensity LED grow lights have routinely higher THC levels compared to identical cuttings grown under HPS. Use of UVA and UVB supplemental light, such as the SolarSystem UVB during bloom can also increase THC levels. A selection of the best LED grow lights on the market can be found on our sister companies website, Crazy LEDs. As well as offering higher cannabinoid levels, LED grow lights produce less heat than HPS lights, use less energy and last longer. LED grow lights are the preferred choice of the serious hobby grower as well as the professional legal cannabis producers.
