Growing Seeds In Indoors Conditions
Growing Tomato Indoors
Growing tomatoes indoors will allow you to produce fresh, flavorful tomatoes throughout the winter months. Instead of consuming flavorless grocery store tomatoes, you will be able to feast on a fresh, homegrown harvest of tomatoes from the grocery store. Growing indoors is also useful if you live in a multi-unit building and do not have access to an outdoor space for growing vegetables.
Select a variety of tomato that grows well indoors. Indeterminate tomato varieties are ideal for indoor gardens. Unlike determinate tomatoes, indeterminate tomatoes will continue to grow and produce fruit all season long. If you are looking for a variety of tomato that will bear a lot of fruit and ripen quickly, choose a plum or cherry indeterminate.
- Heirloom indeterminate include Pink Ping Pong, Siberia, Silvery Fir Tree, Tommy Toe, and Yellow Pear.
- Hybrid indeterminate include Micro Tom, Orange Pixie Tomato, Patio, Ref Robin, Small Fry Tiny Tim, and Totem.
- These tomato plants are not compact and naturally climb. They will require a cage, trellis, or stake.
Plant your tomato seeds in a starting mix. Wet your seed starter mix or potting soil with fresh water until it is moist. Fill a seedling starter tray with a moist mix or soil. Poke one hole in the soil of each cell—the hole should be ¼ inch deep. Insert about 8 seeds into each hole with a tweezers or your fingers. Cover the holes with moist soil or mix.
- Sow the seeds ten to twelve months before you intend to harvest your tomatoes.
- If you don’t have seed trays, you can use plastic yogurt containers or cans.
- If you are planting the seeds in a used container, clean the container with a 1:10 bleach:water solution.
Promote germination with consistent heat and water. Germination is the process of transformation from a seed to a seedling. Tomato seeds will germinate within five to ten days. There are several actions you can take to speed up this process and to ensure its success.
- Immediately after planting the seeds, cover your seedlings with a lid or a sheet of plastic wrap—this will prevent the soil from drying out.
- Move the cells to a warm location. Throughout the germination, maintain a daytime soil temperature between 70 to 80℉. If you cannot heat the space to at least 70℉, consider purchasing a heat mat or placing the plant cells in a sunny location.
- Every day, lift up the lid and water the seeds as needed.
Move your sprouted seedlings to a sunny or artificially lit location. Tomato seedlings and plants require between 12 to 16 hours of light each day. Without adequate light, tomato plants will become weak. As soon as the seeds have sprouted, discard of the cover and provide your seedlings with ample light. If you have a south-facing window, place the cells directly in front of the window. If you do not have a south-facing window, shine a grow-light or a fluorescent light on the seedlings.
- Artificial light sources should be placed a few inches from the tops of the seedlings. As the plants grow, you will need to adjust the height of the lamps.
- If you are keeping your plants on a windowsill or in front of a window, rotate them frequently to ensure that every side is exposed to light.
Fertilize the seedlings. Indeterminate tomato varieties continue to grow and produce all season. To sustain this intense cycle, you must provide your tomato plants with adequate nutrients. Within two weeks of transplanting, apply your first fertilizer treatment. Following the initial application, continue to fertilize your plants every few weeks until it is mature.
- Use a fertilizer that is high in phosphorous.
- Follow the instructions on the product.
Water your plants when dry. After you transplant your seedlings, it is imperative that you continue to water the plants regularly. Assess the soil every day for dryness by sticking your finger into the soil. If the soil is dry, water the plant. If the topsoil is dry but the rest is moist, water at a later time.
- Allowing the soil to dry out completely will yield rough-bottom tomatoes.
Growing Cannabis Indoors
Choosing a variety is of major importance.
Yields and quality of plants grown under artificial lights mostly depend on:
1. the seed variety,
2. whether the plants are grown from seeds or clones,
3. after how many days of growing the plants are put into flowering, and
4. the optimization of the climatic conditions of the grow-room.
Apart from “true breeding” varieties, our seed collection consists of different F-1 hybrids. Crossing two “true breeding” strains (hybridizing) gives F-1 hybrids that possess the so-called “Hybrid Vigor”. This means that the F-1 generation is a lot more potent than either parent. F-1 generations also consist of uniform plants.
Growing cannabis indoors has seen a dramatic rise in popularity in recent years. When done properly it produces excellent quality stash which is usually much better than that sold on the streets. Growing cannabis indoors relies on the use of powerful artificial lights to replicate the effect of the sun. These lights typically take hundreds of Watts of electrical power to run and are commonly HPS (High Pressure Sodium) but fluorescent lights, metal halide, LED light and other kinds have all been used successfully.
Cannabis loves light and the successful indoor grower tries to deliver as much light as possible. Consider 250 watts/m² only as a minimum starting point and realistically aim for 2-3 times that level if possible. More light will mean bigger, denser buds and superior yields. As well as delivering high light levels the successful indoor grower keeps the plants as near the light as possible to maximize the light intensity reaching the leaves and buds. Often the personal medical or recreational grower will have a growing area of 1-2 m² designed below a single 400W or 600W high pressure sodium (HPS) lamp.
The indoor cannabis grower has to be careful that the plant doesn’t grow too near to the hot light and damage itself. If the light feels cool to the back of the hand it will be cool for the plant also. For a 400W lamp, growers may not want to allow plants to grow within 40-50cm of the bulb. Cannabis plants can be bent over and tied if they get too tall, some indoor growers deliberately train their plants this way to get as much of the plant as possible close (but not too close) to the high intensity light. There are no such concerns if you are creating CBD isolates to make products like cbd vape
Certain strains respond well to having the growing tip of the plant pinched out (known as ‘topping’, ‘FIM’ or pinching) after the 4th or 5th leaf pair. The resulting plants are often smaller and bushy without the dominant main growth stem (or ‘cola’) and are preferred for some smaller grow rooms, according to IceHeadShop.co.uk.
Some indoor growers train the plants underneath a metal chicken wire-style screen allowing only the buds to grow vertically while the stem and growing part of the plant grow horizontally. This SCROG (screen of green) technique allows the indoor grower to keep as much of the bud growth as possible equidistant to the lamp, maximizing the efficiency and yield.
Specialist suppliers offer ‘air cooled’ lights for the indoor grower that enclose the light in a glass casing. A fan forces air over the light and outside the growroom via tubing, keeping the grow room cool and allowing the plants to grow taller without burning. Grow rooms are typically kept between 24°C -30°C for optimum results. Higher temperatures can cause the plants to wilt and cooler temperatures may slow down growth. The plants will need a gentle breeze from a fan, and a steady supply of fresh air which can be from your house or from outside. Stale air from the growroom is normally continually extracted outdoors by a fan and de-odorized with a carbon filter.
Those indoor growers that do get caught are often betrayed by the smell of their growroom, so some also invest in ozone generators to further remove odors from the exhausted grow room air.
Germinating cannabis seeds can be done in various ways and the internet is full of cannabis grow forums that document various methods you can also visit iceheadshop.co.uk . One simple method is to simply place seeds about 1cm below the surface of firmly pressed damp soil. A film of kitchen cellophane over the surface helps keep conditions moist and after a few days of temperatures around 20-25°C the seeds should germinate. Growing from cuttings of ‘mother’ plants is an alternative to growing from seeds.
In the first stages of life the seedlings are happy to start with lower light intensities often a meter below an HPS light, or closer to fluorescent lights. The artificial lights are normally ‘on’ for 18-24 hours per day. During this time the seedlings are in a state of vegetative growth, they will continue to grow roots, leaves and branches but no bud.
By reducing daily light to ~12 hours the cannabis plant transitions into the ‘flowering’ phase. This stage normally requires 8-10 weeks (but more for certain strains) and it is during this time that the female flowers form. During this stage the plants gain a lot of bulk and will tolerate more nutrients and very bright light. Some growers introduce supplemental lighting to ensure the very best yields. At the end of this process the plant is cut down and the buds (unpalliated female flowers) are dried. Some growers harvest the plants when they see the trichrome start to transition from clear to cloudy (this requires a powerful magnifying glass/scope to see). This often coincides with the bud producing lots of red/orange pistil hairs. Some smokers prefer bud harvested early, others prefer late- harvested bud. When growing- your-own it is you that decides exactly how you like it!
In general, longer periods of vegetative growth will grow larger plants and support greater yields during subsequent flowering. Typically 2-6 weeks of vegetative growth are used and during subsequent flowering the plants may increase to 2 or 3 times their original height. Some growers use the ‘sea of green’ (SOG) method, this uses just a few days of vegetative growth before switching to ‘flowering’ conditions. This technique produces small plants of low/medium yield, but allows for fast production.
Male plants are nearly always destroyed by the indoor grower as they don’t yield any buds, and given the chance they will pollinate the female plants reducing them to seed.
Feminized seeds are popular with the indoor growers as they virtually eliminate the possibility of male plants. For many indoor growers feminized seeds from a quality supplier are regarded as the only way to go. If male flowers appear at the end of a female flowering cycle don’t panic, simply pinch off the male flowers. The female buds are mature and unaffected by the appearance of isolated rogue male flowers late in the flowering cycle.
The indoor grow room allows plants to be grown in soil or any number of other grow mediums. When growing in soil the cannabis plant benefits from 25% perlite or coco fiber being included. This allows better aeration of the soil. One common mistake by inexperienced growers is the tendency to overwater soil-grown plants. Get to know the weight of your plant pots and water only when the plants need it. Over watering soil-grown plants will reduce yield/quality and slow down plant development.
Growing cannabis indoors will require use and understanding of plant feeds. This is not complicated, all the plant feed does is deliver essential nutrients to the roots, it doesn’t matter whether the roots are growing in clay pebbles, Rockwool, coir or a hydroponic system. Even soil-grown plants will need additional nutrients when the soil has been depleted. Read the instructions on the nutrient labels and avoid the beginners temptation to exceed recommended levels. The experienced gardener can ‘read’ his plants and will learn when to water and feed plants.
Indoor growing allows the plants to develop under closely supervised grow conditions without the normal array of outdoor pests. Once the grower has the right system in place it is a predictable way of growing great quality cannabis, a lot better than weed sold by street dealers. The main challenge for many indoor growers is dealing with the characteristic cannabis smell so that no-one notices it.
Recreational and medical cannabis popularity now extends far outside the earths warm/tropical climates, so for many growing cannabis indoors is the only option. Growing cannabis indoors has never been as popular as it is today, nor has it been as easy to produce superb quality weed. Professional seed suppliers, equipment providers, advice and information are all available on the internet.
Of course it all really begins with great quality seeds – get them from a supplier you can trust.
