I don’t remember if you mentioned how often to fertilize seedlings. I use 1/4 strength 20-20-20 water soluble every 7-10 days starting after true leaves develop.

Always learning new things on next level gardening!One of my favorite gardeners!Keep up the good work!

I'm so excited, first time doing a fall garden, and very much looking forward to it, the information you provide is so understandable and easy to follow, your a great teacher! I am 79 and new at all of this and I am going to have to use the sunlight from the south windows to prayerfully grow in seeds and hopefully get them tall enough to plant outside. Thanks again for all of your dedication and work!

I laughed at myself because before i even watch your videos i immediately hit thumbs up. Lol. I did watch and enjoy video tho.

one of the master gardeners in my area says " weakly, weekly" for containers and seedlings, when they are big enough to need more food

Thanks Brian, your videos are always very educational no matter how many times I watch them.👩‍🌾

1 TBSP per gallon. One half strength is 1/2 TBSP per gallon. 1/4 TBSP per half gallon. That would be 1/8 TBSP for a quart.

I'm learning so much from you. Thank you for the great videos!❤️

Great tips. Thank you for sharing!

Thanks for the info! Can never hear it too often. 🌱

As always, such a helpful video. Thanks Brian!

Great information. Thank you!

I use the Alexa App and a compatible plug-in for my grow lights. Set it up with your phone.

Excellent information, thanks!

If you use boiling water on your seedling mix or microwave it before planting your seeds, you will not have to deal with fungus gnats. I learned that from another channel and never have an issue with them.

How do you keep your seedlings from drying up and dying when you go on vacation?

I’ve used a beet based commercial organic fertilizer in the past and the seedlings loved it, but it seems like it was a groundhog/rabbit attractant. :-( so I’ve gone without since.

When I do my next starts I am so going to remember to water from below. I haven't done that so far because I just found it cumbersome to take the tray outside at that point to dump the excess water. But, I have a plan for next time.

I bought one of the Viparspectra lights from your link. Can't wait for it to get here! I'll still be entering to win one next week!

i have and use 2 viparspectra 1500 pro , came out last year awesome awesome lights very informative content , really dig it

Thanks, Brian. ❤️

Neptune's Harvest (fish and seaweed) .. 1Tbsp per gal.. but for seedlings use half strength =1/2 Tbsp per gal or 1/4 tbsp per quart of water.

I love the mars hydro ts1000. A little pricey to use but the footprint is massive

Hi Brian I wondered if you can do a video on the steps for bringing plants back indoor. I have a poinsettia that’s out all summer, basil, parsley etc. I would like to have inside before it’s too cold. Don’t want the little white bugs though. Vancouver Canada 🇨🇦

In some of your recent videos on the double cup method you advise to keep the water in the bottom cup half way up the cut triangle. This keeps the soil constantly wet. But in this video (How and when to fertilize seedlings) you say to take the trays out of the water after the top of the soil becomes dark brown (wet). Which is correct?

Whats your favorite seed grow light? Is this new light that you installed here the best one out of the ones that you have tested or there are other lights you like more? I would like to purchase something that will last a long time and is good quality. Thank you for this video btw. You are helping us all so much to try to grow some veggies this summer 💚

Very helpful thank you

I went into your website to see what those teal light support items were. I could not find anything like this in your products I love page though.

Just built myself a growlight station that has a top shelf just for storage of supplies and 31" travel from top to bottom for my adjustable 4' grow lights and 24" travel for bottom area of grow light travel. Today at your center I'm noticed you also have a lot of travel, I built my travel remember that I was forced to get some of my plants out and I believe we're stunted because we had a late spring , This coming year I plan to put out about 10 days later than our zone 6 estimated frost date. I believe you said that on a different video of yours. Sujest a "HOW TO Setup a grown light center" I rebuilt my new because my last ( and my first) didn't have enough travel after my beautiful plants grow after 8" and suffer from my emergency setup area and added lots of my time to adjust to my problem of not knowing how much travel to setup for. Thank you Sir for the teaching of us you tube students.

If you sprinkle ground cinnamon on top right after planting the seeds, it can reduce fungus.

Just saw your video , cool i knew how to fertilize starter plants to harvest. But this is the first year i am actually trying to grow veggies from seed to harvest. So i kind of was unsure when to start fertilizing. I think you cleared this up. So its after the first true leaves aka the next leaves after the seed leaves. And for an organic fertilizer like a balanced 20 -20-20 NPK you just half strength/dilute it. And fertilize every 7 to 10 days. Ahhhh

Great Video! I watch another video with the self watering trays that's what I'm going to use. Water the same way and leave the water in the tray?

You are the best👍

Hello, how big should the tomato leaves be in order to to start fertilizing or I should start off the moment the true leaves start popping up🤷

Growing chard. Seedlings just came up. I’m excited to have a fall crop.

Would the Neptunes Harvest also work as a general houseplant fertilizer. I grow Microgreens and use oceans solutions as a fertilizer but I’m only growing seed leaves. Probably why when I grow plants out to true leaf for outdoors they don’t grow well under lights with oceans solutions . Good video thanks.

Thank you. I learned something from this video. New subscriber here. I grow seedlings in an open garden covered by caterpillar tunnels. During the rainy days , algae grow on the surfaces of the seeding trays. Aside from fans, can you recommend other ways of keeping algae from growing?

Have you also used neptunes harvest on houseplants as well? I just ran out of my usual fertilizer for my indoor plants but have this for my spring seedlings.

What do you have the dimmer setting at on the light?

Did you transplant the carrots and cilantro? I've never read them are best when direct sown

I've been trying to grow perennials right now echinacea and columbine...I potted them on as soon as they had real leaves into a potting mix that had slow release fertilizer and also fed them for a bit, then I noticed deformities in the echinacea leaves so I stopped. The columbine had different symptoms, yellowing leaves of bottom leaves...the bottom leaves of the coneflower are also drying out. Am I using the wrong soil? Do I need to fertilize regardless? I'm at a loss...I do have grow lights supplementing a south-east window

Hi, what about spraying the foliage of seedlings with the fish and kelp mix? Is this recommended?

I have never used a grow light. Usually put my seeds directly in the soil in my garden.

Make sure your seedling tray is on an even level before you bottom water or you'll end up soaking one end and starving the other!

Thanks Brian ...I just fertilized before the true leaves ... what do you think might happen? Have I destroyed my starters?

Do you fertilize with every watering?

Got my first bottle of Neptune’s Harvest Tomato & Veg! Thought I’d give it a try after watching your “Wonder Blend” (or whatever you called Miracle Gro) video.

Actually video sir. thank you.

So awesome, And Perfect Timing! Answered all the questions I was going to ask the google 🤓 ...I trust you more tho 👍🏻👍🏻🤓😁

When you start your perennials will you do a video on that along with what you are planting!?😍

I setup hundreds of seed trays for starting my seeds and it'd been a few years since I gardened and I accidentally added diluted tea fertilizer mixed with water to all the trays. Did I just ruin all my hard work? I'm just planting the seeds tonight and wanted the soil to be moist. Considering flushing from the top with a garden hose on the shower setting but then my soil will be wet for some time and probably unusable, was looking to plant seeds tonight.

Did I hear you right? You start your carrots indoors and transplant them into the garden after? I'd like to see the transplant video of carrots! Love you videos.. you are the only one I actually follow!!!!!

My nasturtiums are leggy should I start over or are they good since they are vining plants??

Where did you get those seed trays from

Where did you get that light stand?

What if some seeds germinated later than others or haven't at all? Would you fertilize or not? My seed starting set up doesn't allow for bottom watering, it's the jiffy peat pellets. I'll use something different next time.

If I direct sew seeds outdoors, do I fertile the soil?

I finally gave up somewhere around 2:50.

Fertilising content from 2:58

Can you use a granular fertilizer on seedlings? I bought some garden-tone from Espoma and wasn't sure how to fertilize my seedlings using it!

Video starts at 3:00 good Lord the plugs dog!

Can we use worm tea to fertilize seedlings?

I'm taking some time off from gardening but always appreciate your great info. Good to know about the less obnoxious smell of the Neptune's harvest. The stuff I've been use can be quite aromatic, especially since I start my seeds in a small closet. I will probably swap brands when I need to buy some more

Would you ever use a slow release pellet fertilizer vs a liquid quick release fertilizer for seed starting fertilizer? I never really used slow release on starter plants to harvest but maybe it would work well at the seed to seedling levels in beginning? Probably though best to stay with the same type a fertilizer as starter plants to harvest goes just at less of a concentration so you dont burn them. As the fertilizer itself is probably good enough to use at any stage its just the concentration/dosage that changes for younger plants. Just thinking out loud so happy i came across your video clearing up a few last minute issues.

I put worm castings in my seed starting mix instead of using fertiliser

N-EXT makes some of the best organic products on the market and their prices are very reasonable.

Doesn't "sweet pea" usually refer to the ornamental perennial varieties?

I’m so sad because I just fertilized my seedlings after planting the seeds. I’m new to this and I never did it. Lol I pray they still grow. Lol

How often do you fertilize your seedlings? If its every time you water, then how often do you water. Thank you

How often do you apply this fertilizer to your seedlings?

Is it safe to use Miracle Gro Liquafeed on 3 week old plants?

Lookin' fwd to what U say, but I heard going gentle is good, like rabbit feces & worm castings, either in a compost tea or just piled next to the trunk, a dripline distance away, or between, so the tree can choose to use it & not feel imposed upon ;-)

To fight and prevent mold, sprinkle the soil with cinnamon.

I thought spinach and beets are supposed to be directly planted outside. Please explain why you started them inside. Thanks!

Hi Brian! Question: Is it a bad thing to start the seedlings outdoors? I don't have all those fancy lights so I just saw, water and out they go. I think putting them out side makes them tougher 🤷 Maybe? Thank you in advance. Good luck with everything 🤞😁👍❤️🍀🌷

Quick question, I know you like using Neptune Harvest products. I can only get their stuff on line or at Amazon. I really like the Tomato and Vegetable and fish/seaweed although I just ran out. I got other stuff to get me thru this year that I can just dilute. Prices continue to rise I’m sure you know. Amazon has the Tom/Veg on sale but don’t know if I should buy it now and Dave or if it’s “fresher” if I buy it next spring. Will it go bad or lose strength if I buy it now and wait to use it next spring? Just don’t wanna lose money if so. Thanks !! Really enjoy your channel and all your great information. Learning a lot !,

I cannot find the green light stand. What am I missing?

hi hope your having a great day😊 I was wondering what can I do if I have my seedlings way to much fertilizer by accident?

Does this apply to onion seedlings as well?

You mention Neptune, but don't mention the ratio of NPK. Is it 20:20:20?

Brian looks stoned at the beginning of this video. Is it possible that he is good at growing thing’s other than tomatoes? 😂🤣😁

I miss my seedlings with a spray bottle… how would I measure my fertilizer for a spray bottle? It says 1/2 Tsp for seedlings per 1 gallon, I believe, but I don’t use gallons😩

I dont like the tomato and veg for my seedlings as the color is light green and Im used to having a darker foliage so Im switching for this purpose.

I like to use a 555 in the house because it doesn't stink

I have the dry neptunes harvest 😫

Do you think that the Neptunes Harvest products on Amazon are authentic? Amazon has them much cheaper but I'm skeptical about purchasing them for their?

Did you ever try worm tea.

@ 5:25 "If you don't go with organic the chances of burning your roots are much higher". Dude if you're using half-strength synthetic fertilizer and you apply it once there's no way you're gonna cause fertilizer burn to your seedlings. The worst you'll do is not encourage as much root development, but they are in a small tray anyways. Other than that, I love your channel man keep it up =)

You used to use fish emulsion fetilizer who need a higehr concentration per water. Like for me when i used it it was 1:20 ratio with a very low NPK. Like 0.5 0.4 0.2 NPK. Neptune harvest fertilizers are not fish emulsions a they use complete different process. Better for our plants and bacteria and the ratio of dilution is 1:128. A massive difference

Synthetic fertilizer burn results when people do not use proper ratios-which should even be reduced for seedlings. The latest university studies are showing the highest yields come from combining organics and synthetics.

Have you considered or have you ever done Korean gardening?

But one additional question what happens if you want to use a synthetic fertilizer like a miracle grow or another synthetic based liquid fertilizer. Can i just one 1/4 strength or something. Or is there actually a math equation for it. I am just going to wing it for this years experiments but it be nice to know. And what about instead of using a quick liquid release if one just mixed slow release pellet instead of liquid. Just unsure about the aspect of concentration/amount but as for when/timing all set. So its not so much a mystery as much just now getting the proper fertilizer concentrations down for synthetic blends would be great. Probably over thinking it and just should try what works best. Nice video!!!

FYI he starts talking about fertilizing seedlings at the 3 min mark

Why do my seedlings not stand up but fall over

You know what makes for a really expensive grow light? The $50 no name Chinese grow light that barely works and makes you say, “I should have just listened to Brian and bought a Viparspectra”

Your seedlings look leggy, you should lower the lights to stop that. 👍

Can you tell me why one can't email you directly? You don't have to reply but if we ask a question, how do we get an answer?

tomatoes growing in two cup;s are fed and watered from the top. isn't that correct./ jerry

The Viparsprectra lamps are too much money for me I will stick with my shop Light.

Action starts at 3:00. You welcome
