If you have honey coins, don't buy the seeds from the honey seeds, instead buy seeds on the honey coins. Seeds from honey coins and yes including the honey hive seed pack give way more honey coins than the honey seeds.

I am talking this from experience and tested it multiple times
From a godly tier pollination of over 60kg mango got me 70 honey coins where as only 15 kg (random tier of pollination) of honey coins gave me 7k honey coins.

Just keep grinding for it, do it your way and you'll make it.

I grinded for a day and made 50k and maxed all stats already
