Using speed gro after planting not working?

[lcg3092]

So, from wiki, you are supposed to be able to use speed gro after planting a crop, and it still has an affect.

So, I'm planting Strawberries, and just did a test. Planting them on the 13th, then adding speed gro on different patches on the 15th, 16th, 18th and 19th, still makes them all pop up in the 21th, which is the normal date without any speed gro (since it's supposed to round down number of days, I expectect them to be grown on the 20th).

Am I missing somethinh

You can use fertiliser/speed grow while it's still a seed, not after that. So if you plant the seeds that morning, then add fertiliser the same night before bed, it'll be fine. Try adding it the next morning and it won't do anything. Hell, it shouldn't even let you ADD it if the seeds have reached their initial plantlet stage, but I guess that might've been changed in 1.6.

only seeds can have fertilizer put on them. I think only water retaining soil can be put on at any time.

Only some fertilizers need to be used before plant sprouts. Many now can be used at any time during plant growth. Speed grow is one of them. And they DID. They put it on after, proving you can put it on after it sprouts.

Anyway regular speed grow only ups the crop growth rate by 10%

Speeding it up by 10% of 8 days is already less than a day's worth of growth saved. Putting it on later, would be even less since it would be 10% sped up for only those days left. But of course there's no difference since the application is already under 1 day it could shave off.

Must be a 1.6 change then, because that wasn't the case before.

Was a 1.5 change actually.

Didn't changed in pure unmodded 1.6 .
Once planted seed survives a day in soil, it can't be fertilized without pickaxe usage.

to explain further I think after 1 night of being watered it can't be fertilized, so if you plant it and don't water it you should still be able to apply fertilizer the next day

Again it depends on the type of fertilizer you're using and this was about speed gro. Go try putting speed gro on a sprouted crop, it works.

"Some crop fertilizers must be placed before the planted seed sprouts, the other fertilizers can be used at any time during plant growth."

You can see in the chart that only the basic and quality fertilizers say BEFORE seeds sprout. All others are before OR after(anytime).

I'm unmodded and due to being careless have put speed gro on plants partly grown by accident that were near my seeds.

It was changed in 1.5 you just never notice for some reason.

If you've planted strawberries at or after the 13th a 10% speed boost isn't enough to get an additional harvest, you'd need at least a 20% boost.

Disregard I misread my chart.

[lcg3092]

According to the wiki, 10% should be enough for an extra harverst, and that does make sense if speed gro rounds the number of days down, which I thought was how it worked. So even though 10% of 8 days is not 1, it still rounds to a 1 day reduction.

Sorry about that mistake, i'm fighting off a bout of covid and mushbrained my chart reading.

It's been like this from day one when fertilizers been a thing.

The fertilizer is applied "ondaychange", so when the next day occurs, it checks if fertilizer has been present.

If yes then hoedirt's function "applyspeedincreases" fires, and shaves off the % of days required to grow the crop.

It's been written in the wiki for years that you need to apply the speed increase fertilizer before you plant the crop or at least, before you end the day, otherwise it will skip the applyspeedincrease function.

That's correct, since only when you end the day and the crop was watered, it applies the speed changes as the crop "grows" overnight.

Right but they didn't put any on, on day one. It only speeds it up from the day you put it on. So if you put it on a couple days later you're not getting the full 10% of 8 days growth. So starting it 2 days later speeds it up by 10% for 6 days not 10% of the whole 8 days. It doesn't work retroactively when you put it on late.

There would seem to be a cut off of a certain percentage where it gives you a whole day off for a certain fraction of a day saved. So you couldn't put it on say, day 8 of 10 and have it instantly grown day 9 as you'd not get a whole day's growth saved from the 10% boost from one day on the crop.

Or there is a chance that it isn't working as stated on wiki, and adding speed gro after sprout does not work as stated. It's not the amount of days, since using speed gro on parsnip reduces growth time from 4 to 3, even though 10% of 4 is just 0.4, it still rounds to a full day growth reduction.

Then maybe it always rounds down a day long as put on day 1 but takes into account missed time after that and has a cut off. Since you seem to be testing you can test with a product that is over 10 days to grow and try putting it on on day 2. Should get a day cut off in that case if it's not broken.
