RainScience GrowBags provides extra oxygen for your roots

RainScience GrowBags provides extra oxygen for your roots

Better drainage than old school grow bags or plastic pots. Organic Earth has some new sizes in stock.

The most technologically advanced Grow bags available

 Rain Science® grow bags makes container gardening a lot easier.  Grow bigger and healthier plants.  

  • Air root pruning creates masses of fibrous feeder roots which maximize plant growth
  • Minimized root circling allows for longer life in Rain Science Grow bag
  • Rain Science® Grow bags material is Certified safe, nothing is exchanged with the soil and is great for all natural gardening 

How do they work?

With normal fabric Grow pots there is often a problem with mold build up and root rot from the fabric staying wet. The wet material does not allow air to pass very freely. The special mesh from RainScience GrowBags allows for better drainage than traditional grow bags.  Rain Science Grow bags provides more oxygen to the soil because of  improved air flow through the fabric. This air flow facilitates a process called air root pruning, where the plant creates a bunch of tiny feeder roots which are better at absorbing nutrients,  this in turn leads to increased plant growth.


Why not just use Plastic pots?

  When your roots grow, they will quickly reach the container walls. With Old School plastic containers, these roots immediately start circling and continue to circle. If you look at the root structure from a plant in a plastic pot you find a few large roots growing in circles with very little side branching, the roots will soon bind upon themselves, restricting nutrient uptake and eventually lead to root bound plants and death.

Why are Rain Science Grow Bags® better than Traditional plastic containers?

Rain Science grow bags aerate your root zone and plastic containers do not. Root  Aeration stops root circling by Air pruning, helping your plant build a stronger root structure. Better roots means a faster growing healthier plant. Old School plant pots also hold a lot of heat, which can lead to a whole new set of problems. Rain Science Bags actually dissipate heat keeping your roots at an optimal temperature.

Are Rain Science Growbags® Good for organic Gardening

Yes, Rain Science Grow bags® meet the requirements of the CA Department of Public Health “Standard Method for the Testing and Evaluation of Volatile Organic Chemical Emissions.We leach nothing to the soil and exchange nothing with the environment. If the rest of your grow is organic you can feel confident using Rain Science. 

What is air pruning?

Air pruning is a natural process that happens as plant roots come in contact with fresh air near the walls of the growbag, the root tip stops growing, essentially pruning itself, this causes the rest of the root to branch off with many tiny feeder roots, instead of a few circling roots. These new roots will continue to colonize bag, allowing the plant to maximize uptake of both water and nutrients.  

Are Rain Science Growbags Reusable? How do I clean them?

Yes, Rain Science Grow bags® can be reused over and over again. You can wash them with dish soap and warm water. If you need to sterilize your bags they can be soaked in a solution of H2o2 and water. They are also washing machine safe, so feel free to throw them in with the laundry.

Do I need to use a special potting mix?

You can use any potting mix with Rain Science grow bags®. We recommend something you are familiar with.  Because of the extra aeration, your soil may dry out faster and  you might wish to adjust your watering schedule or growing medium depending on the moisture requirements of specific plants.

Growing outdoor; the sun is for free

Growing outdoor; the sun is for free

Spring is in the air ! It’s time to pop those seeds and start growing your own, in your backgarden or somewhere, secretly, in the woods.

Outdoor cultivation

The cheapest and most natural way to grow Cannabis is outdoors. The sun always rises for free and the entire plant recieves enough light. The lower branches develop much better in the sun than indoors under artificial light. It’s a disadvantage that the neighbours, the police or other smokers can see your plants and maybe even steal them.

Ground or pots?

Place your plants in the sun (at least 4 hours direct sunlight a day). Plant them in the open ground or in pots. Plants rooted in the ground usually grow larger than plants restricted by the size of a pot.. However, pots make a plant mobile and the bigger the pot, the larger the plant will be. Fill the pots with some good living soil. Some real easy to use products to make your own super soil, are Lurpe’s Earth Vibes Super soil and BioTab’s Mycotrex. And new to our list of products: Organic Earth Mix for Long Flowering and for Short Flowering and Organic Earth’s Mycorrhizae. Above all, let nature do its work, give the plant a sunny spot, but never let it dry out.

Spade the garden

If you want to plant your plants in the open ground it is best to prepare the spot beforehand. Make sure the soil is loose and well-aerated (spade!). Make holes about half a meter deep and one meter in diameter. If the earth has to much clay, add for example sand or perlite, basalt meal, lava meal or bentonite and mix it with the earth. An acidic ground (pH<7) needs lime. You can make alkaline soil (pH>7) more acidic by adding organic matter to your garden such as compost, tarred manure, peat, or a combination of these. In order to increase the fertility of the soil, add compost and /or manures. For instance Greenhouse BIO feeding or Plagron’s Supermix. Make sure every plant has enough space. We advise 1 m2 per plant.

Flowering stage

The sooner the plants are planted in the soil, the bigger they will be at the end of the season. When spring frosts have past (in the northern hemisphere that’s after the Ice Saints ) you can plant your plants outside and take cuttings until August. The plants start flowering in the middle of August (when the days are getting shorter).

Forced flowering outdoor

If you want to harvest early, you have to shorten the photoperiod (the light cycle) to twelve hours a day. You can do this by covering the plants with light-tight plastic or by moving the pots to a dark room. This way it is also possible to grow tropical varieties.

What kind of seed to choose

Autoflower varieties are very popular to grow outdoor. Easy, robust and fast are the characteristics of an autoflower: 9 to 11 weeks after germinating, you can already harvest. If you start early enough you can have 2 harvests in one year. And for an optimal result it is the best to flower them in the mids of summer. For example: starting to germinate a seed with autoflower-characteristics, on the 15th of june will give you an harvest in the beginning of august. To see our choice in autoflowers you can go here and choose the filter option for autoflower.

Go for something real

Personally I prefer to choose strains that have a normal growing and flowering period which you can harvest in september or oktober. But if you make an obscure space and darken the plant, you can harvest earlier. Anyway, if you want to choose a seed, and flower it with natural light it is recommended to look at the time of flowering.

Keep an eye on the weather

Although the climate change makes our summers hotter and longer, there is no garantee for the wheather. You don’t want your plant to be washed away because normally the autumn rains have started in october. A plant like Tropicana Punch is very risky because the harvest is forecasted for the end of october and the risk of mold is rising with the number of rain showers. Less chance for mold is when you choose a plant with 7 or 8 weeks of flowering -period. Go here to pick a seed with the recommanded floweringperiod.
