Right now I'm keeping mine outside but that won't always be an option I feel like you big guys must have a more elegant solution lol.
I’m not a ”big guy” but, You could possibly build a “boys only club“ tent/area to keep them in library mode until you need them.
Or bloom them out like I do and collect the pollen, however as mentioned by Heisenbeans, pollen has a very short shelf life and needs to be properly dried to be kept.
I have a couple males going atm too, and I just borrow a light from my bloom tent (a simple 200w CFL I use as a side light, does the job just fine). Anywhere you can let it bloom safely is the key.
If it’s only a male I’m blooming, I don’t really need anything too big regarding a light as I’m not really looking for a huge monster.
Males tend to push a lot of that yellow stuff given half a chance regardless, and they don’t need to be big to do it from my experience. Another thing they don’t need is a 5 star hotel, boys will be boys, they just need “somewhere“ to make it happen.
I keep a spray bottle with just water in it to make sure accidents are as limited as possible, when the boys room is closed up, I give the outside area a spay to kill off any possible airborne pollen from getting where it isn’t yet wanted, and I make sure the pray hits me too, even though I avoid the females afterward.
Again though, I’m no expert but I hope that helps at least a smidge.
