What you can learnA useful failed radish trial documenting thinning, transplant rescue, weak bulb formation, premature harvest uncertainty, flavour results, and equipment-size concerns.

Actions:1 Planting
Useful practices
  • using two seeds per sponge and thinning later
  • moving a thinned seedling into a split sponge
  • starting with a very small nutrient dose
  • comparing performance in a Harvest and a larger Bounty
Problems encountered
  • poor bulb formation
  • elongated carrot-like radishes
  • Hailstone and Black Spanish produced only leaves and long roots
  • small harvest size
  • bitter or chewy flavour in some roots

*The days were calculated automatically and approximately.

The Hailstone and Black Spanish are not doing anything other then the leaves and a long white root. No ball forming. Here are the others. They are tiny compared to what everyone else is growing. Radishes must not like me growing them LOL

Those two varieties take longer, just give them some time

S

How do you know when they are ready to be picked?

E
ERR0R1755

I recommend going by the width of the radish.Black Spanish Round - 3-4" wideCrimson Giant - 1.5" wideHailstone White - 0.75"-1" widePurple Plum - 1.5" wideYou can always pick radishes early and they're still edible, but you don't want to let them go for too long or they'll start to get woody.

last night I ate one before bed and I think it put me in a coma it was so hot..didnt open my eyes til 9 am !!!!!! With the Giant Crimson, I can't eat them after 20 days.My preference and what I learned from my project. They lose their juicy crunchiness and mild heat . Today is day 19. My project is ending today.

S
Shawn

I picked the Purple Plum as it looked like maybe it was ready. That was the one that grew long not round.Well I do not think it was ready. Mark said it was chewy and bitter but spicy.This will continue. My next one will be in a bounty for the better lights. They may grow faster that way too.

S
Shawn

I am going to end this sometime this week. I want to clean the unit before the GAL.The Black Spanish and Hailstone are doing nothing but growing the leaves. Mark tried the Purple plum but it was still bitter. I will pull the Crimson T his week. They are on the small side. I do not know if it is because they are in the Sprout or maybe it is the temp in the house. I WILL try them again but in a large machine.I will get a picture tomrrow

How hot is your house? Radishes are a cool weather crop so they do best between 50F-70F, although you can add a small fan if your temperatures are higher than that.

S
Shawn

Not hot. We have central AC. There is circulation in the room. We have an open floor plan so plenty of circulation. They may just not like me LOL or the wattage of the Harvest.

E
ERR0R1755

Do you know roughly how much nutrients you gave them? Maybe it was too much (so too much nitrogen), and they focused more on leaves?I grew a Purple Plum Radish in my Harvest Elite as part of this timelapse.

S
Shawn

I do not remember.

S
Shawn

I pulled the three Crimsons. The larger of the three Mark said was very good. Not real spicy however. Maybe because of the size. The other two were pretty small.I will try again using a larger machine in the near future.

S
Sher

I enjoyed watching your experiment.

S By Shawn

Ok what have I done wrong? They are not looking like they will be round. They are looking like carrot shaped. I think I am failing at radishes LOL... I looked at one that I split the pod and they are long and thin and not round.

ERR0R1755

I think they should be fine? At least in my experience, once they start forming the bulb, the bulb doesn't get any taller/longer, so you're probably just going to get some large radishes

S
Shawn

Ok, I will wait and see

S By Shawn

I took a picture this morning and was going to post it, however I just walked by and I looked and now they are not only taller but have a visible 2nd set of leavesI should have planted them in a Bounty, I know they would be growing faster. The only lone one I have in the bounty is further along

I guess now would be a good time to add nutes? If so how much? ERR0R1755 ? @cornne ? Or do I wait longer?
Conversation
E
ERR0R1755

Now would be a good time! I don't have much advice on the amount, since I use the PPM method so I always add 2ml to start. Corinne might have a better idea.If it helps for a reference (since you can compare numbers to get a relative idea of nutrient strength):Radishes need 840-1540 PPM.Lettuce needs 560-840 PPM.Bell peppers need 1400-1750.Basil needs 700-1120.

S
Shawn

Ha, I do not test water ph ppm or anything. I will start with 1ml and see and add more if needed,

ERR0R1755, Should I thin to one now?

E
ERR0R1755

Now would be a good time!Also, regarding your Black Spanish Round - if that one doesn't start looking better, you might want to remove and reseed it. I've seen that happen sometimes with radish seeds, but I have no idea what causes it.

S
Shawn

Ok thinned the 4 down to one. There is another Black rounded about to come up thru the pod so I will wait and then take out the wirey one.

U

I am looking forward to the tastes of these different varieties. I had 2 wiry ones as well and I replanted them.

S
Shawn

The second Black Spanish popped up and over the label last night. So this morning I took the wiry one and placed it into a sponge I cut down the middle. It is taking up residency in my Bounty with the peppers for now. Hopefully it will take and then I will have 7 instead of six. I wish I thought about this with the ones I thinned LOL.

This morning .. all but one but it looks like it wants to open.ERR0R1755, should I life the sponge up now a tad or leave it as is?

ERR0R1755

No need to worry about it until it starts forming the bulb, which will be a while from now. The only thing you need to avoid is letting the bulb grow "into" the sides of the pod, aka letting the bulb be constrained by the size of the pod.

S
Shawn

Thank you

S
Shawn

WOW, I just took a look at them and they have grown since this mornings picture. I know @cornne said that she saw growth before her eyes. Now I believe it (not that I doubted her).

How exciting!

Just wait til you have the bulb sitting on top..that is the time to watch it grow by the hour(well...not quite)! It is amazing.

Today I am finally starting my radishes (thanks to ERR0R1755 for the seeds) in my Harvest Elite. See below diagram for layout and types.Park sponges with 2 seeds each and will thin at a later time. No nutes until after germination.Wish me luck!

shawn caught the radish bug too

If I look into each pod, two of the Crimsons have life starting to come out of the seed.

That is what gets me every time...the fast growth!
