If I get one MH IBL male and one Regular MH male. Would you let both loose on the girls or pick one? Thus far, the MH IBLs, or at least the three grown are more on the thin leaf haze side and the regular more robust.
One heck of a good advice, my friend. Thanks.Not a breeder myself, but one male at a time for an open pollination, unless necessity dictates otherwise. Hopefully you're keeping cuts of the girls for Round #2; and if you have, then may as well keep a cut of the second male for Round #2.
If you have enough space to work an expanded plan, like transplanting the second male to it's own pot and giving him his own tent in a separate room, then you could use both males this Round, by selective pollination, of single branches on the girls.
One heck of a good advice, my friend. Thanks.
It all depends on what you plan to do with your F2s.
If you only want to use them for production and stop at the second generation (F2), you can do a [1 female × 1 male] cross, as long as the two phenos you chose are vigorous enough.
If you want to continue the line further and create F3s, F4s, F5s, etc., you must cross as many females with as many males as possible to avoid potential inbreeding problems.
Some say [10/15 females × 10/15 males] is enough to continue an F2, F3, F4, etc. line ad infinitum.
If it had been a hybrid cross, with different females and males, you could have selected the best female and the best male and done a [1 female × 1 male] cross.
My only intention is to select the best plants from each round. It is a humble endeavor.Zero0 made a good point about your action plan being determined, ideally, by your ultimate goal(s); but us "hobbyists" who don't have enough time, money, space or years left to do massive sifts, we bend the "rules" a bit to adjust to working within our means. You never know when Lady Luck will strike, and you hit upon some real gold, against the odds, with little time investment.
If you're intending mainly to sift through the F2 generation for the best expressions, or outliers, that alone will take 3-5 years on a small hobby scale, to work through all the seed you can make from just 2 rounds of open pollinations with a few plants. If you score 2 decent males, it's a good idea to keep them alive for outcrossing projects; especially the IBL, if you can only keep one male going long term.
Ultimately you'll need to determine the best male of the 2 based on their offspring; which is one reason for keeping the pollinations selective or separate. If you're committed to a long term relationship with them, and have the space for it, you can select your 10 females & males from the f2 generation to do an open pollination of them all, with your male(s).
Later down the road, if you're working through the generations, of separate lines descending from the 2 males, you can reintroduce the separate lines to each other, to restore some vigor, if necessary. Good luck!

Nice male you got.The MHazes and MH hybrids have only sexed this week and I would like for as little seeds as possible with those (even if there are comments around where Shanti says seeded buds are as potent). What do you guys think?
Thanks, my friend! I will do just thatNice male you got.
If you leave him chances are that every pistil will be pollinated and the plants go into seed production mode and will not make many new pistils anymore.
I would pull him out with a small rootball and put him outside if it's possible in the shade for 1-2 weeks more until you can collect enough pollen to hand pollinate some branches of your choice.
I will be posting pics soonHow does it look? @dbbrainer
Hopefully this isn't the end, as today it would be the second unfinished thread![]()
