Pollen

Is there a reliable source for pollen that delivers to the EU? I hardly get any males from my regular seeds, and those that do develop are hardly useful for my purposes.

My question wasn't answered. I asked if there are dealers for pollen. Not how I produce feminized seeds and not any nonsense about temperature determining the sex, etc. I need good pollen from a few specific strains to improve my genetics. It could have been that someone here could help me.

@Chucky324 Changed growing conditions don't affect what comes from a seed. Seedlings are either male or female, the latter can hermaphrodite due to stress.

Hello. I wrote this down a long time ago. Here it is; You get more females if you have : Higher nitrogen levels Higher humidity levels Lower temperature levels More blue light Fewer hours of light (than you normally have in the clone/seedling room:18 hours of light) Start about the 3rd set of leaves for 3 to 4 weeks. You get more males if you have: Higher potassium levels Lower humidity levels Higher temperature levels More red light Longer hours of light ( than you would normally have in the clone/seedling room: 18 hours of light) Start at the 3rd set of leaves and continue for 3 to 4 weeks If you change your environment slightly you get more--- I once got 9 males from 10 seeds with this method. Hope that helps. Chuck.

@Y0ink The treatment with colloidal silver doesn't turn a female into a male. The stress just causes the female to produce pollen, a survival bloom. This creates feminized seeds, so pure female genetics; XX + XX = XX. Such seeds are suitable for personal cultivation, but they are not suitable for breeding.

Also Colloidal Silver treatment helps the plant to turn male 👊🏽🍀
