According to other comments found on the Collected Tidebloom Honey page, this can be repeated once per week, so it's really only for the rep.
No one can tell you if it's worth your time to farm the jelly every week or not, but just to quickly put it in perspective, 35 [item=168828] is equal to 280 [item=169106] (one stack +30). You can possibly loot enough royal jelly to at least make up for those 30 (at least four, which equals 32 thin jelly) but you'll likely also get [item=168825] in the mix. which for this purpose is worthless as you can't convert them to any other jelly, and there is nothing to buy with them. The only thing you can do with those is AH them or give them to a friend/guildy that's still working on it.
