How to grow Runtz XL Auto marijuana seeds

Learn to grow indoors

This extra large autoflowering strain has a short life cycle, with less than 8 weeks from germination to when it's harvested. By taking care of it correctly and proper lighting, it can produce yields of 400-550 gr/m2 and grow up to 0.6-1.2m.

When growing indoors, you can plant up to 9 specimens per m2, which will efficiently use your 600w HPS lamp. Similarly it is important that you control the pH levels of the water you use to water your plants. This is to make sure that the nutrients administered are being absorbed correctly by your plants radicular system. If you are going to use a mixture of peats or plant directly on earth, the pH should stay around 5.5-6.0 during the first vegetative weeks and 6.0-6.4 in the flowering stage.
