I live in places where pineapple grow best, and currently have a row of different varieties(that i don’t know who are what) in my garden, with a few of them fruiting. Since yours are indoor with climate control, i’d say water heavily but infrequently, maybe once in 2 or 3 day depend on said temperature and humidity. From my understanding they’re pretty resistant to draught, my area has been 32-34°c most of the year since forever, and i only been watering them every two day or so if i can help it. My soil is very clay-ish so it can retain water, but also not drain very well. Lot of grower advice to not overwatering it to prevent root rot. Fertilise it once or twice a month.

They love sun so you have to have long light on period(8 to 10 hours, up to 12 hours if you wanna follow the equator day/night cycle).

Pineapple crown will take a looooooong time to grow, shortest 2.5 year, mine took 3 years for some to fruit naturally, others still not fruiting yet but i’m in no rush. So about 3.5 years for it to harvest.

Once the fruit is growing, there might have slip growing out from the base of the fruit. Cut those off to stop the energy going into that and fully focus on the fruit. Once harvested, don’t cut it down, wait for the sucker to grow, then cut it and plant those the same way you do with the crown, they will grow a bit quicker, lot of grower said around 1.5 years for it to fruit but i haven’t experienced it yet.

It’s not a hard plant at all, just need a lot of patient.
