Guerilla growing in the forest

Germination - I planted the seeds at home in a light mix substrate. After 5 days, I transplanted into the previously prepared substrate Ingredients of my Substrate : 10l soil, 1l perlite, 0.8l vermikulit, 0.8 worm humus, 30g Guanokalong powder, 30g Guanokalong seaweed powder, 30g Guanokalong veg pearls. Unfortunately, the weather forecast called for a night temperature of 7 degrees, so I made a greenhouse out of pet bottles Blue granules are protection against slugs, I have had very bad experiences with them Watered with water from the stream directly from the spring
