Northern LightsRuderalis
Automatic Northern Lights strain.
Our Northern Lights comes from an old phenotype that is difficult to find nowadays. We cultivated it in a hydroponic system but it is adaptable to all substrates. This is a small, robust plant with a slow and compact growth pattern. It has fleshy leaves with a deep green colour and thick buds with loads of resin. Its fragrance and taste are very sweet

Discretion, speed, careful package.
It is the second seed to plant, very good germination, solid and healthy seedlings, varieties that support defoliation well. Nice for a beginner like me.

2 males 👎 I bought 5 seeds germinated 3 of them all grew ok but only 1 started flowering at week 3-4 so after 7 weeks of waiting for the other 2 to flower I changed the time to 12/12 to see if it's a photo instead of auto and I was right! Both were photo males :( instead of autofems 👎 Now I am too scared to use the rest of the seeds so most likely they will go in the bin.
Checked expert seeds reviews and was horrified to find that I am not the only person having this issue and the owner of the seed bank doesn't respond to any of the negative feedback only response to the good ones.
I am not looking for replacement or refund I am just here to warn you about it I am not taking the chance and risk again and will stay away from this breeder I just wish I checked the reviews before the purchase maybe because there wasn't any review on this strain yet so this is my review. ☮️❤️

This is the second time I've ordered this seed. Last year they were the prettiest plants I grew, hands down. Beautiful coloring to the leaves and flowers.

I'm on week 7 of veg an no sign of flowering witch leads me to believe this is not an autoflower. On top of that It has all kinds of leaf mutation. Not very happy with pyramid seeds would not recommend
