Flowering Time

Flowering time for indoor is counted from the day the 12/12 light cycle is started and is based on the standard 4 weeks vegetative time from seed. It can vary depending on style of grow (seed plants/clones, hydro/soil, etc.), the products used, and quality of plant care. Outdoor flowering is also influenced by the time of sowing, soil/nutrients/water quality, weather, and pests. 


Yield will vary in each individual grow because it depends on many factors that you influence: the size of your plants, light intensity, quality of plant care, cultivation style, products used, etc. Our max. yield is based on gr/m2 under 400W HPS/m2, organic soil cultivation with seeds and a 4 week vegetative time.


Aroma or taste is based on our results in organic soil cultivation. It can vary according to your style of grow, substrates, use of additional products (pesticides, fertilizers, etc.) and the drying/curing process. Avoid giving fish emulsion during flowering, using plant or bud boosters, and similar products.

Germination results will vary when pre-soaking seeds in water. Fresh seed stock can germinate under these conditions - but not always. Most often, only pre-germinating in moist paper tissue works for fresh seeds. But this is also not full-proof and should only be done if you have enough seeds to spare.

To prevent complications, and achieve the consistent level of high germination rates that you should be getting from our seeds, please trust our advice and follow our guidelines in the GERMINATION GUIDE. Customers who soak their Mandala seeds in water or wet paper tissue do so at their own risk. We are not accountable for any failure in germination or complications caused by this method. If you have any issues regarding germination please read our Germination Troubleshooting Guide carefully before contacting us.

Please read our Germination Guide before germinating your Mandala seeds. Due to the high quality and fresh stock of our seeds we advise against soaking the seeds in water or germinating in paper tissue. >> READ MORE

Detailed Description:

Welcome to the new edition of Krystalica. We used an almost identical "sister" of the previous mother plant for breeding. This has resulted in the appearance of a delicious strawberry aroma in some of the plants, which enhances the already fruity properties of Krystalica!

Everyone who has even remotely enjoyed our Satori will appreciate Krystalica as another essential connoisseur strain. She offers a great package deal that is hard to come by: impressive resin production, good yields, easy growing, and a superb high. Krystalica is smoother and less dramatic in the initial phase of the high, therefore rarely triggering anxiety common to many other sativa leaning strains. The medical applications for Krystalica are extensive since it has top THC levels with a very pleasant high to match.

Krystalica can be grown indoor from seeds or clones. Use 400-600W HPS/m2 for best results because this is a high performance strain and may not flower well under low light. In hydroponics impressive yields can be expected – especially if you have selected a mother plant that brings the extra pounds on the scale. Long shoots extending from the bottom two internodes should be pruned in hydroponics or if your grow space is cramped. The remaining branches are of medium length but may require some support during late flowering if the buds become particularly heavy. It is usually sufficient to tie a thick string or gardening wire around the outside perimeter of the plant. The plants grow well in SOG and can be planted in close rows. With 4 weeks of vegetative growth under 400W HPS/m2 in quality soil you can expect the plants to reach a height between 70-110 cm. Use at least 5L/1 gallon containers for growth and 10L/2.5 gallon for flowering for plants from seed (clones can be raised in smaller containers).

Bud development is unlike a typical sativa and quite dense with some plants exhibiting broad indica-type buds. Trichome production can reach amazing heights, extending to the sun leaves, so it pays to keep back-up clones and select the most spectacular individual as mother plant or for breeding projects.


Outdoor cultivation is recommended in regions with warm summers, or up to the 45°N. Krystalica is heat resistant and will grow well in arid-hot environments or a greenhouse. The head buds and side shoots can grow to extraordinary proportions and deliver bumper crops. Further north the performance and harvest date will depend on local weather and length of daylight. Sowing of seeds should commence when there is no more danger of nighttime frost. Sowing can be extended until end of May if you prefer to cultivate shorter plants. Start seeds indoor if the weather is cold and move the seedlings/young plants outdoor or to the greenhouse later. The same can be done with cuttings – but make sure that the light cycle is appropriate so that flowering doesn’t start too soon outside. Most Krystalica's have good mold resistance (see details on our website for phenotypes) but plants should be harvested if it rains frequently in the last 2 weeks of flowering.

Product History

Sativa Vol. 1-Krystalica

Selecting mother plants

In biology the word "phenotype" is used to define the distinct characteristics of an individual resulting from the interaction of its genes with the environment. When we talk about "phenotypes" we restrict this to a major set of differences between plants in a strain. It is unnecessary to distinguish between plants and mark them as a distinct "phenotype" because of an insignificant variable.

Krystalica has two distinct "phenotypes" which we will call Type A and Type B. 

Which phenotypes in what % you will see in your garden depends on how many plants you grow out, plus the environmental conditions and cultivation style. You determine phenotype as much as the genetics may do! The less plants you have, the more slanted the results can be. If you wish to select the best female of a particular plant type you should therefore grow at least 10 females (20 or more seeds).

TYPE A (see photo gallery)

  • Highest calyx-leaf ratio, almost leafless top buds, buds are more spaced out.
  • High resin content on nearly all plants.
  • Grows tallest individuals.
  • Very mold resistant, best choice for humid climate and/or extreme greenhouse temperatures (40°C/105° F or more) during end of flowering. Both scenarios carry higher risk for bud mold.

TYPE B (see photo gallery)

  • Large pyramid shaped head bud and central body.
  • Highest yielding individuals.
  • Resin can extend to larger fan leaves.
  • Very heavy side shoots that may need support.


Approximate plant height is given below for a greenhouse scenario with vegetative time of 4 weeks in sunny weather, or 5 weeks with mixed weather conditions. Seedlings transplanted into 4 liter/1 gallon pots in quality soil and put under 12/12 after 4-5 weeks or planted late to coincide with natural decrease of daylight. Females planted into the ground after sexing with 4-5 plants per m2 (10 sq.ft). For close planting (or sea of green) the average distance between plants can be 60-70 cm/23-27.5" and between rows 40-45 cm/16-18". This still allows for easy access to plants for gardening chores.
Plants cultivated in the ground from the start may grow taller. Plant height is also determined by nutrients, weather, overcrowding, and plant care. Regular feeding of nitrogen rich fertiliser, or a soil mix with excessive levels of nitrogen, should be avoided. Overcrowding will make plants stretch competitively for light. Cold and overcast conditions will slow down growth.

Type A: 165 cm/5.5 feet on average, 190 cm/6.2 feet tallest
Type B: 140-175 cm/4.6-5.8 feet

(Information given is only an approximate guideline!)

For greenhouse cultivation without artificial 12/12 late planting is recommended. This controls height in regions with long daylight hours during summer. Plants can also be pruned before sexing to grow shorter plants. In this case all shoots will probably require support during end of flowering due to the heavy buds. Cuttings generally grow shorter than plants from seed. They should be moved from indoor to outdoor to coincide with the correct light schedule.
