Would a normal spider spawner work if I built a farm meant for cave spiders [closed]
Solution 1:
Unlikely without proper adaptations. Cave spider is 0.7 block wide and 0.5 block tall. Regular spider is 1.4 block wide and 0.9 block tall. That means if the collection channels are 1 block wide, regular spiders won't fit; if any passages are through a slab-sized gap, regular spiders won't fit.
The general concept should work, but you will need to adjust the sizes of passages.
