Growing Broccoli Sprouts - Do they need to be kept in the dark for the first 4 days? An Experiment 

When you rinse the jars twice a day save the water and water your plants with it .great video you are excellent teacher. Best wishes from Ireland 🇮🇪

Sulforaphane starts decreasing after the sprouts start turning into microgreens, which happens around day five. That is why you should control the growth until day five by keeping the sprouts in the dark or low indirect light.

As a college professor always told me, “A test is worth a thousand opinions!”

Keeping my sprouts on the kitchen counter instead of the cupboard will help keep me from forgetting to rinse them. Great video, thanks !!!

I love your videos because it isn't the standard "I googled this, so now I'll preach it as fact"

I very much appreciate your scientific method. You cleared up my question after watching about 20 RU-vid Sites. Your verbal explanations are extremely clear and concise. No Nonsense--No Bull. Very informative. Thanks

You went to a lot of work here and it is very much appreciated!!!!!!!!!!

Thank you. I was confused by the unlimited videos saying to grow them in the dark. The first time I grew sprouts I was a complete novice. I grew them in the light and they turned out excellent, therefore confusing me after I saw allllllllll the videos instructing growers to place them in the dark. Your comparison confirmed my beliefs. You helped me see the LIGHT : )

I use jars that are probably twice the size of your jars, but I only use 1 tablespoon of seeds per jar. The sprouts have more room to grow and will then grow better. I also rinse them around every 4 hours and they are ready to turn green on the third day and soon are ready to eat.

I love it when someone says "I have no clue".

This video was very informative. I am a virgin sprouter and haven't even started yet. I am so glad I came across your video. Thank you! ♥️✌️🌱

This is an excellent experiment video. I'm thinking that the stronger taste of the more developed sprouts/microgreens may come from an increased amount of myrosinase enzyme, that with glucoraphanin, produces the sulforaphane. This is suggestive of a more nutritious product, which would also be attained from just allowing more growing time. Another enhancement trick, for producing increased sulforophane, is to freeze instead of refrigerate the sprouts. The freezing process produces molecular crystalization, which lices the cellular walls, which places the myrosinase and glucoraphanin reactants together, to more readily form the sulforaphane. This mimicks mastication (chopping, chewing), which acts to break down cellular walls, putting these reactants together. This works much the same way as snapping and mixing a chem-light, where the reaction of two chemicals produces a luminescent compound. Since heat deactivates myrosinase, all cruciferous vegetables (broccoli, cauliflower, kale, cabbage, brussel sprouts, etc.) should either be eaten raw, or chopped fine and let sit for 45-90 minutes before cooking, to allow the sulforophane reaction to occur, or add a myrosinase source after cooking, like mustard, mustard powder, or horseradish, and then chew well.

Honestly that was amazing... I, too, was binge watching sprout videos on RU-vid trying to figure out which guru had better results. Your experiment just saved me an experiment of my own and a ton of time! Awesome format. This was fun.

Good job setting up the test, but..... I wondered if temperature played a part. Under the grow light the temperature might have been higher, causing an earlier sprouting. As someone who sprouts seeds for transplanting to a garden, I know that temperature is important. So, I'm just adding a variable that wasn't controlled for. Still, the darkness might not be an important factor.

LIke other posters said, you are an excellent instructor. But more than that, you have disproved a very huge assumption and made anyone who follows your research a lot more productive.

She is adorable. Even in her explanations. This was of much help.

Thank you Tikki. You leave no stone unturned. Great work !!

Fantastic video! Thanks for testing and putting this information together! The commentating is perfect.

Thanks Tikki, I was wondering about this and you have answered my question, well done!

Hilarious…. I was literally thinking that keeping it dark was probably unnecessary and was hoping for it to be that way because I want my sprouts on the countertop where I can remember to rinse twice daily. Otherwise it’s out of sight, out of mind for me. Also, my pantry is absolutely packed. I was literally going to conduct the same experiment and now I don’t have to! Thanks for this. I feel comfortable sprouting in ambient light

I’ve been wondering about that!!! Thank you so much!!! Just found you!! Appreciate your time💟

I love your thorough experiments and videos!! Thank you for all the work so we have so much information.

I LOVE your dry sense of humor!!! Very funny towards the end! - Enjoyed watching! - Susan Burns

Thank you so much for doing this experiment! I've just started sprouting and I've been wondering about this. Very informative and appreciated!

Thank you for investing the time to do this experiment and video-document it all! Very helpful and informative.

This was helpful. I'm uncovering my sprouts right now.

Thanks Tikki! Great experiment, I love your delivery :)

That was an awesome experiment and answered some lingering questions that I had. Thanks!

Beautiful! 💖 Thanks so much from a newbee sprouter - so glad to find your excellent video before starting. Love all the helpful comments too. Bless you. 🤗

wow I always stored my sprouts in a dark place the first 4 days. I wont have to now. Thanks so much. Just got a new batch of broccoli seeds to sprout.

Thank you for answering some of my questions, and I love your sense of humour!

Direct and to the point commentary, Well done. I don't have extra cabinet space or a pantry, so knowing I can just leave them on the counter makes this a lot easier. thank you

Thank you for this video, I'm sure you have helped thousands of people with growing their broccoli sprouts. I was confused but you've cleared up a few things thank you.

This has been the best video on sprouts and microgreens in all of RU-vid. Thank you

The ones from the grow light have a beautiful color. I haven't grown broccoli sprouts yet and now I really want to. Thank you for the information.

This was great! Thanks for putting in the work to experiment!

Wonderful. Absolutely wonderful. You had a question, tested it with multiple dada points and presented the findings in an easy to understand format. Thank you.

This was so interesting. I am completely new to sprouting and found this very useful.

I look forward to your videos! You are so helpful! Thank you! You motivated me to grow some sprouts today!

Tikki, Great test procedure!! No nonsense in your explanations. SUPER, INFORMATIVE video!! Thanks, Tikki!!

Thank you so much, Tikki! I'm new to this and appreciate your expertise, experiments and comparisons!

Thanks for this.....best part of the video is when you said, "As to the nutritional value, I have no clue"'. Love the honesty.

impressive quality control...WELL DONE!

Excellent video both editing and info!

I just love your videos. Thank you for sharing!

Didn't I just learn something new as a newbie in growing sprouts,thank you for your break down on darkness vs light ,,I've been covering with a towel the first 3-4 days now I can eliminate that step,cheers and happy munching

Thank you for experimenting. I really appreciate your videos!

Thank you Tikki O. for the video. You answered all the questions I had after my first try to grow spouts...

Good job with the common sense!! Thank you so much. I just got my seeds today. I got a salad mix so I'd have a well balanced addition to my eating. Keep up the good work! God-bless you!

Every person you showed said the same. They just googled it and repeated something wrong they could check for themselfs. I think their information is very misleading for a lot of people. So your video was very helpful. Thank you!

Thank you so much for doing this experiment. I've just started sprouting and there are thousands of videos on youtube with no comparison or verification. Your video is very useful.

Thank you for doing this. I grow my sprouts near my kitchen sink. I tended to forget them when I left them in the dark. They get ambient light. They always turn out fine.

Another clear video from my favorite hydroponic channel

Awesome post… Thanks for taking the time to compare…

Great experiments !!! Thank you so much !!! I have learnt so much from it in so many aspects to apply to and improve my own sprouting ! (And I’ve been sprouting on and off for 10-some years yet still got unclear about certain things, until your this informative video.)

Thank you so very much. Your painstaking explanation has helped clarify a million things. I think Option 2 works well for me, I don;t have a window nearby, so ambient light is best. How much you must love your sprouts and sharing that joy!

Thank you! Just now learning about sprouting…this really helped me!

Loved this! Thanks for posting this experiment

Thank you for this video. I was all ready to start with keeping them in the dark and now I don’t think I will!! This is my first time sprouting; they are soaking as I type this!

Your awesome! Thanks for this! I"m keeping mine in the light now.

Thank You Tikki; This was a very informative video. I learned a lot.

Nice work! I had this question and your video just popped up randomly like you read my mind... thanks.

Tikki - you are brilliant at what you do!

Extremely useful and informative - Thank you for this information.

This was a fun video. Thank you for sharing!

Thank you so much for this experiment. I really appreciate all the work you put into letting us see for ourselves what works and what doesn't work. You save me a lot of time and effort. God bless you

Very good information! My life just got way easier!

Thanks for taking the time to do this and document it so well. I'm about to do my first batch and this helps a LOT!

Thanks for doing the experiment. I love this video 🖖

Thankyou Tikki, you are the best!!

Very interesting! Thank you so much for sharing.

You are so funny! Thanks that was super helpful! And enjoyable to watch :)

You are amazing!! Thanks 🙏🏻 you have removed all my doubts!

Thank you for this video! This is amazing for someone like me who is just starting out. This is very helpful

Wow Thank you for this experiment, I was wondering the same thing about light vs dark. GREAT JOB

Thank you for the show I learned a lot!! Great information!

Excellent experiment and well done. Thanks for the information. 👍

Amazing comparison video! I have been looking for someone who’s experimented with this exact idea. I think I’ll leave my sprouts in indirect light for first few days then move to direct light the last day. Bravo. Thank you for this!

Interesting experiment! I am just starting with sprout growing here in the Philippines so appreciate your info.

thank you...i tried this method...it seems superior to all the others...will continue using it now on

Thank you for sharing your test and results.

Amazing , I love experiments like this , thank you so much .

I'm a new subscriber. And a new gardener. I don't know much about gardening, but I do know your channel has been more helpful and informative than 90% of what's on the internet. I'm sure as I watch more of your videos that number will keep higher. Thank you so much for the great videos.

Awesome! Great science, thanks for making this video!!

Thank you so much for doing this and sharing your results. You were totally thorough about comparing growing conditions, times, quantities. Based on your experience I will eat 3 or 4 day sprouts grown with either speckled direct sunlight, or pure indirect light. For Reference: her Experiment Proper begins at 5:12. Video time up until 5:12 is discussing details, methods, and materials of this experiment, also outlining procedures of other people who have made videos about sprouting broccoli.

Wonderful video. Learned a lot. I've had a bag of seeds for some time but haVe been afraid to try this. I WILL NOW. THANK YOU

Great point. Thank you. Excellent I always wondered about the light. Actually the one styayed under ambiant light look a bit greener... great !!

That was quite interesting, thank you!

Thank you for the great information! This is so helpful.

Thank you for that experiment. I always wondered about that darkness part

experiment contents deserve more views than contents with groundless claims

Super! Thank you sooooo much. And by the way, the lettuce looks good as well and grew wonderfully during the 🥦 experiment.

Thank you for this video!! I was wondering myself.

thanks for the video. saved me a lot of wondering.

Great video, thank you for posting!

Thank you for the time you took I order to give us this knowledge!!

Very interesting. Glad i clicked your video!!

perfect timing as i'm just getting ready to start sprouting again after a long time. i'm glad you watched dr. rhonda patrick; i've been following her off and on for years. she does say something about at what stage the sprouts are best consumed for highest nutrition but of course i have forgotten. thanks for the inspiration!

Great video! It was very informative.

Wow! I enjoyed this video. Very informative.
