These figures are ranges, not promises. Flowering time, harvest date and yield vary depending on growing conditions: the grower, the method and the season's weather. "Mold resistant" means mold tolerant: less prone to mold and slower to be affected. No strain is 100% mold resistant. How we set these numbers →

J'ai démarré les 5 semences commandé et seulement 3 sur 5 ont germé. J'ai donc esseyé de les faire germer d'une autre méthode que celle recommandé mais sans succes. heureusement que ces 5 grainne venais avec le cadeaux autrement j'en aurais eu seulement 3. J'ai deja commande a multiple reprise et jamais eu ce meme probleme c'est peut etre la genetique.

Just finished up my first grow. Pop 2 of these with one of the free seeds that came with my order. The free one failed to sprout. The 2 WW however shot up great. After cutting and drying and trimming I ended up with a total of 221g of bud from 2 plants in around 5 months. I'll be. Smoking good until my next grow. Can't fault these seeds 4 stars because the others seed I bought from here failed and they sent me replacements.

@eric - The issues you describe are not a fault of the seeds.
1 - You said second generation. If you are using seeds from harvested plants, those seeds genetics will be broken down with each generation. You will get herms and males at this point. Do not use those seeds.
2 - If you choose to use those seeds, you just need to watch your plants when they mature. Cull any males so they do not pollinate your females.
It would have been better to rate the product and not your mistakes.

The yield is very high. The 5 seeds grow out different flower types, with straight hairs, curly hairs, and a big lemon smell. The white hairs are not harvested for almost 10 weeks. After two generations, it is found that there are male and female plants, which is harmful. All the 500 trees in my room have seeds, and the loss is huge.
Sorry this one didn't turn out as hoped. Every pack is covered by our guarantee: delivery is guaranteed, germination is guaranteed at 80%, and if your seeds didn't pop or the wrong pack arrived we re-mail a replacement — no arguments, just contact us.

Final results of white widow fem, indica phenotype, very large colas, thc 15-18%
7.5 oz at 63 days, super soil, ph 6.2 @ 7-900 ppm
Sweet mild skunk flavor, long lasting relaxing high, I decided it is good enough to keep for a while , I still have four more seeds, every seed will be a little different. that's how we gind the fire strains. I have kept strains for 12years continuous, I am searching for the keepers. This takes so much time and discipline

My first of 5 seeds is very very big producer, itis only 26 inches tall and easily has 224 grams
I don't know about the potency yet, the smell is nice but mild, it really doesn't have a lot of trichomes so hopefully it will still be potent
