When grown indoors, this plant keeps her tiny shape and doesn’t stretch too much during the flowering stage. As she’s an almost 50/50 hybrid, she’s perfect for indoor environments, for growers with limited space, or for those after a more discreet layout. Don’t be fooled by her restrained size, though: you can expect a surprising indoor yield of about 450 grams per square metre without any problems.

You can defoliate Amaretto Tarmac Auto regularly to keep a good airflow between the branches, which in turn helps increase the size of the secondary buds. During the vegetative phase, encouraging the greatest possible airflow avoids stagnant oxygen pockets in which pathogens may grow. And don’t forget that this plant releases a strong aroma, so you should consider using carbon filters in your grow room.

Make sure you also have the correct grow lights. Most experts recommend 600W LED or HPS lamps. High light conditions help increase Amaretto Tarmac Auto’s THC levels, although you can also consider side lamps to support the lower bud areas.

Indoor growers must keep a temperature range between 21 and 26ºC during the vegetative phase, and between 18 and 24ºC during the flowering stage. Reduce night temperatures to 16ºC during the last few weeks of the flowering to increase the size, weight, and stickiness of the buds, and to stimulate the production of terpenes. You can also consider Low Stress Training to increase the plant’s exposure to light and, therefore, her yielding potential.

This strain works equally well in warm Mediterranean climates and in milder continental areas. Having said that, and thanks to her autoflowering resilience, she can also thrive in colder regions, where she can still produce high yields during the warmer months. Unless you’re lucky enough to enjoy a temperate climate all year round, consider setting up a greenhouse for best results. Planting in pots is also vital so that the plants can be relocated more easily during extreme temperature drops. Depending on the location and on the applied growing techniques, each plant can produce over 500 grams when grown outdoors, provided they are given the right care and attention.

Outdoor growers should sow in a sunny and breezy location, set up some protection against the elements, and plant companion species to keep pests at bay. If you grow Amaretto Tarmac Auto seeds outdoors, it’s important to keep the plants in the same direction as the sun sets, which will allow them to receive the maximum amount of direct sunlight each day. Prune excess leaves at least once during the vegetative stage to promote airflow and light penetration.

When growing indoors, and providing that the electricity cost isn’t a problem, you can have a continuous crop of Amaretto Tarmac Auto seeds throughout the year, if your grow setup allows for it. Outdoors, as the growing season normally runs from March to October, you can grow up to three crops. In a warm and sunny climate, for instance, it is best to plant from March to May, from May to July, and from July to September to obtain the best results with the highest amount of sunlight and when the temperatures aren’t too cold.

Although summer is the best time to grow autoflowering strains, everything depends on where you live. In areas with Atlantic or continental climates, it is less sunny, with shorter summers, so you can usually only grow one crop. Therefore, the ideal outdoor planting window starts from 3 to 5 weeks before the summer solstice, allowing you to take full advantage of the sunlight. The weeks after the solstice help maximise resin production thanks to the higher intensity of the ultraviolet rays.

However, you can also grow two crops in regions with milder climates: you can plant the first grow between mid-April and early May, when the cold has passed, harvest in late July, and plant again in mid-August, so you’ll be harvesting again in October. It all depends on how cold and rainy the autumns are in your latitude.

In any type of setup, you need to pay special attention to your nutrient solution; and because Amaretto Tarmac Auto is sativa-dominant, she can be sensitive to nutrient excess. This strain only requires a moderate nutrient regime, so be careful with excessive feeding: it is best not to overdo it in terms of nutrients, as it’s always easier to correct a deficiency than to deal with over-fertilisation, which can lead to irrecoverable stunted development.

Water only when the soil feels dry to avoid suffocating the roots, and use a substrate that is as aerated as possible. It is always best to use small amounts of water at regular and frequent intervals, rather than excessively soak the substrate (especially in the first few weeks of growth, which is when the young roots are more sensitive and excess fertiliser could end up burning them).

A good growing medium consists of ¾ soil and ¼ coco coir or perlite. The more coco coir or perlite added to the soil mixture, the greater the amount of oxygen and air pockets, allowing for more frequent watering and a much more established root base.
