There is going to be a small time adjustment concerining pollen collection , you will have to get thinking about that fast when you flip your lights , a plan
You can just pollinate the room, and let them do thieir thing ( im against that ) but its not my grow , its yours , so i can just make suggestions...
A suggestion can be , identify your female regular plannts - i think the gelato is reg ?
So you will use the gelato to make seed with his pollen , or recieve pollen if female
Take one -2 male sssd male pollen bearing plants , , keep them seperate ( not really necessary ) but they will make different genetics , take your left over sssd females and decide if you want to pollinate the entire plant ? I wouldent , or just pollinatd half or 1/4 of the plant...by dusting pollen on the 3 week old pistils....
You can use a good fine 1/4 or 1/8 inch brush , or even finer , or q tip to apply pollen ...
You will need to catch the pollen when male sacs open , use glass , tin foil , or parchment paper to collect or store the pollen , collect it in another room , and dont tie the plants down or secure them where you cant move them freely
If pollen sacs open when you disturb the plants by rocking or pushing them , the delicate flower will open and if your fan is on .....then everything is going to get seeded , probably even your neighbors grow down the road,
So the idea is timing is a little tricky , you either want to collect the pollen as it happens and store it , or you want to start your males a few days to a week later to begin flower stage , the males will develope faster than the females during the pollination , so you have to time it right,,,,,
If all this is giving you a headache , then just let mother nature take take iits course....
Ps i dont do the dark before flip or any other extra dark things at harvest....
