i keep forgetting that you're a small channel. i dont get it. such high quality. One thing that would be awesome if you showed was a rate for the farm. This is the only thing that could make this even better! once again, brilliant video and farm!

This is the Xiumavoid design from several years ago. I've been building a very similar design since at least 1.13, possibly 1.12 - but my current design incorporated a trick from Illmango's "cactus science" videos to improve the throughput a small bit. I use smooth stone SLABS for the floors above the first floor, though any slab will work equally. I prefer green glass to clear, but I've also used other items like cobble for the early starter stage. Cactus AVERAGES about 1 "grow" every 17 minutes - waiting 5 minutes is NOTHING on a cactus farm. Do NOT need a light source. I've build these completely underground and unlit a few times and they still work the same.

i did the farm it was very easy and nice video btw but it doesnt want to grow so after 5 min still 0 cactus in the chest can u help me?

what is the name of your shader? very nice video
