As is mine, i breed about 10 different varietys.
making batches of poly-hybrids is a good time. you know that the seeds will be a random grab bag of different phenos. i have some nice poly-hybrid seed lots that have turned out some great ganja.
the crosses i have made in the last few years:
purple kush(f) x northernlights(m)
whitewidow(f) x northernlights(m)
(whitewidow x northernlights)(m) x headband kush(f)
(whitewidow x northernlights) x sour diesel(f)
(whitewidow x northernlights) x sensi star(f)
(whitewidow x northernlights) x blue mystic(f)
ak47(m) x sour diesel(f)
ed rosenthal's superbud(m) x sour diesel(f)
trainwreck(m) x sensi star(f)
((whitewidow x northernlights) x sensi star)(m) x sensi star(f)
i got every single one of the seeds that i started with from seedbanks, with the exception of the sensistar and the purple kush.
i know what you mean about seeds piling up. i give 10-packs to any grower that i know of each cross. i love seeing my seeds growing. it's the best
