Hydroponic Gardening & More with Brent

Book is done!
Are spaghetti squash and butter nut squash edible as micro greens
After how many days did you harvest??
Hi, great series of videos you have here – thanks for sharing. Just wondering, what is the dry weight of sunflower seed you use here for one tray? I saw something but wasn't sure if it was wet or dry weight. Thanks a lot – and do you have a cilantro video?!
Have you posted the bread recipe yet? It sounds good.
Wow, over 2.5 lb without using any growing medium! How many grams or ounces of seeds did you start the tray with?
Excellent result !
Nice …I want to learn to grow microgreen organic veggies to improve health. 😊
Hi @Brent. That's a good yield you got from the tray but what was the weight of the dry seed you started with? Sorry if I missed this in the comments or video already…thanks!
looks great, though that is a lot of "stem" – personally I try to just get as much leaf and less stem as possible – the nutrients are in the cotyledon leaves aka microgreens – if selling, your customers will appreciate more greens and less stem – just my .02 cents from my own experiences
thank you for sharing! very helpful! I have a building with 11,000 sq ft basement which is 90 years old. I think it will make a great place for growing.
your neighbor pressure washing his driveway. lol gotta love those pressure washer loving neighbors who have really clean driveways. lol
If you used no soil, why would eating the root be harmful? Serious question.
For weight, use water filled gallon milk jugs.
Brilliant! Thank You for sharing 🙂
Isn’t your outdoor washing (and then harvesting) the least clean thing that happens to the sprouts throughout their life? Indoor hydroponic growing on clean equipment seems much cleaner than outdoor garden hose on wood table. Isn’t it possible you’re making them exposed to more harmful biologicals that way?
Hey Brent – Love your enthusiasm and willingness to share info – great work! One question for you, – When you spray your plants/seeds with Af spray, do you leave it on them, or do you wash them off later?
From soaking to harvest, how long does it take you?
When you kept the seed in the jars and soaked them for another 18 hours – did you cover the jars so they were in darkness like you would if you had them in trays and under the plastic cover? I was wondering if all your no medium crops could be germinated in jars and then transferred to the trays later?
Enjoyed your video and your granddaughter sounds adorable!
Thanks for the link to the trays! 😊
Ever though about using the no rinse sanitizer used for brewing? http://www.brewinternational.com/sanitizer-star-san-32-oz/?_vsrefdom=adwords&gclid=Cj0KCQjw-uzVBRDkARIsALkZAdm9tZdjdyxGF6lYYrSfV-PIBk_PWOxz-QpsYXLzl-pyFdBu_KBdeY4aAjMeEALw_wcB
When you put your soaked seeds in the trays are they in touch with the water below or do the roots reach for it? Thanks.
I'm not finding your sanitizing mix vid…Link please! Thanks…..
Where do you purchase the trays you place your seeds in, can't find that particular tray. Thanks!
Thank you. Nicely done
Hey Brent, can you please reveal what's in your nutrient water. I've been MGing for about a month now and find it fascinating. Right now I use 10 x 10 trays holes/no holes and potting soil with peralite. I interested in trying with so substrate at all. Please give me some guidance of where to go or what to do. Leroy
Don't use bleach, use food grade hydrogen peroxide to santize
Hi I am from Quail Tracks Micro Farm in North East WA
For months now I have been watching 100’s hours of You tube Micro greens videos and learned a lot from all the hard work people have been kind enough to share. I have recently found an easy solution to the Sunflower hull removal problem. It works great for me and I would encourage you to share it on your videos, after testing it for yourself, please mention I shared it with you. I cannot do the video’s myself but really enjoy yours.
Sunflower Hull removal
When the Cotyledons come out and still have the hull stuck to them, move the tray to Bright intense light, being careful not to burn or wilt the plants. The cotyledons leaves want that light and will by themselves kick the hulls off within 24 to 48 hours. When most of the hulls are gone move the plants to dimmer light to get the growth you want.
Small hull removal
Everyone I have seen “Pets” the tray of greens to get the hulls off, to bad because the greens were pristine before the hand was put on them. Better idea – wear disposable plastic gloves when petting to remove hulls that way the greens stay clean and eatable right from the tray.
Another idea I like better and use for my greens is using a “basting brush” to paint, tickle, or jiggle the hulls off. The old basting brushes were harsh and bristley had firm bristles but the new ones at Dollar Store or Wallmart have soft brush parts. They are only $1.00 to $4.00 and worth it. I keep it by the trays and take 5 seconds to tickle the plants when I think of it. They look like colorful small paint brushes.
Keep up the good work, QTMF Owner and wanna-be farmer
did they taste like bleach, soaking them like that?
You may want to experiment with uncovering earlier. The would get taller. I've also eaten them after the first true leaves have formed. I'm growing on a layer of unbleached muslin. Much cheaper than coir and other substrates. Biodegradable.
Cool idea using oregano oil for disinfectant. I use capsules and oil on my body but had not thought of this. Thanks.
Id think you would have a hard time with mold even with the fungal spray you made. Do you use a dehumidifier to help combat any other mold problems?
Once again with the awesome method brother! The commercial growers are mostly still using substrate. I see its not nessesary.
1:9 seems extreme
