very cool! thanks!

Edit: if only I waited a minute... haha! How big is that farm? I'm sitting on about 11 acres with roughly 4 cleared and debating dedicating some space to hot peppers. Successfully started growing jalapenos and savinas so far in the middle of Virginia.

What's the name of the book you had there? Where do I get it? I've been in the landscape construction business for 8 years and it's time for my to spread my wings. I need to get on this.

What's that tool you are using? I am a complete beginner

I have a 5 gallon bucket in my room with 3 plants and I fill it once a week with my runoff. It's not, "drain to waste" hydroponics, but I get runoff every time I feed. Some of the recirculated tables I've seen have 40L reservoirs. That's twice as much water each week that's being used.

Thanks for the info. Quick question, can I only do 1 phase? Say can I only be license for irrigation (say I am only interested in doing irrigation work). Thanks!

FANTASTIC breakdown and this is coming from a lifetime plumber. Thank you for enlightening us ,well done with the multiple angles drawings .

Im prepping to take the tests. Im an experienced irrigation contractor, but I want to expand to all phase. Is Landscape Construction 3rd addition specifically for Oregon? Thanks

I think I read that the 5 extra questions are "experimental" and don't count toward your score. They're just trying out questions to see how people do on them. Thanks for making this video!

Do you need a landscaping license for installing turf?

Very good video Can you film a video on how to get the business license please. I am taking the test right now, but after that i want to get the license for the business. Thanks

Nice!

Excellent video. What you covered is the foundational elements of both systems but not the data needed to determine which system to use. Let me give you a real world example of drain to waste. Actually, the application is a back-yard gatdener one. For the last 6 years I have been using a dutch bucket drain to waste system to grow tomatoe, cucumbers and peppers with great success and low budget. In 5 gallon buckets i have 60 percent perlite and forty percent vermiculite. The vermiculite holds the nutrient solution longer. I pump solution, during the middle of the growing season, twice per day for 30 minutes through 4 gpm nozzles for each bucket with cheap low pressure pump. The buckets have a 1 inch hole two inch up from the bottom for drainage. I doubt there is more than 2 to 4 percent waste. My yields are very good. Others that i know using a recirculating method are feeding 3 times for one hour. My costs and water usage are less.

Awesome video, just discovered this channel, hope the best!

Excellent video, very balanced perspective. One kind of off topic question - since you are standing behind that board, are you writing backwards?

Hi Mykl, I am currently studying for the modified license exam. How long did the entire process take ? I have my first potential clients and I want to give them an idea how long it will take for me becomelicensed and bonded. Are all tests at a testing center? Thanks, Gaby

Do you have a Recirculating system you would recommend for newbies to hydroponic growing. I have been a soil man for years but would like to get into hydro

So if I use a buffered nutrient than drain to waste is best from your video here?

Are the test’s multiple choice??

May God Bless You Guys For Caring Enough to Help the Food Creation Process To Be Better For Future Generations 🙏 ❤ Jesus Loves You and Thank You!

Thank you for this video. Makes lots on sense. It comes down to the time you will have to make a choice on these two

Keep the water level as low as possible in the bucket for the recirculation system. Top feed 24/7 with a good flow. Use a float valve to add from a primary rez to the lower rez. use the smallest submersible pump to ariate primary rez. Have to completely drain whole system once a week. Run nutes at half strength. No air pumps. Hydroton and 12" netpots. Set it and forget it up to 6 days or depending on size of the primary rez.

Hello, there this video is very helpful. To obtain your sprinkle license is there any specific education the backflow courses

This is ve tu helpful thank you! Question, does the Landscape Construction book you mentioned has all the study material for an All Phase LCB? Backflow etc….

Where to buy one of these?

Cool 👍!! Get to know the secret > *promosm* !!!

where are they located? awesome greenhouse!

grow food now !

I prefer to make my own nutrients which is cheaper if you grow a range of different crops. With one set of base chemicals you can make any formulation which is more economical than buying a sack of preblended nutrient for every crop type and growth stage. Another option is to use a preblended nutrient as a base and amend it with individual chemicals to create a different nutrient. In any case, i`d recommend gaining a basic understanding of nutrient formulation, it adds another string to you bow as a grower. Fwiw, a 25kg sack will cost the same to ship, whether it contains a preblended nutrient or just calcium nitrate :)

I agree with most of the points you made. I have to disagree with the blanket statement that recirculating is more water and nutrient efficient vs drain to waste as it is also dependent on the system. Running an NFT system drain to waste would be very inefficient, but a genuine aeroponic system that delivers just slightly more than the plants need at that moment is considerably more efficient than the recirculating option. A benefit of drain to waste you didnt mention is the ability to monitor the water and nutrient uptake in real time which isnt as easy with a recirculating reservoir. If the nutrient`s elemental content is fixed you can compare the inlet and outlet ppm difference which can be used to optimize nutrient strength for best efficiency. The same can be done with water uptake, if you know how much is delivered to the plants and how much is sent to the drain you can make adjustments. Most folks wont realise that plants uptake water and nutrients at different rates throughout the day and night. If you take hourly measurements you will see the water uptake increasing and nutrient uptake decreasing in a linear fashion as light intensity and temperature increases. If the system allows you to tailor the water and nutrient delivery to meet the plant needs in real time, you`ll find drain to waste considerably more efficient than recirculating. As an aside, nutrient formulations for recirculating and drain to waste are different because a recirculed nutrient must have buffering agents to maintain a stable PH. Adding ph up or ph down affects the elemental balance of the nutrient, so even if the ph is good the elemental makeup could be adrift. The run off PH is a good indicator of nutrient uptake, for example, nitrate uptake is reflected by a rise in PH, potassium uptake is reflected by a drop in PH. Fast growing crops can make recirculating reservoirs harder to manage. In the case of tomatoes, they will strip large amounts of potassium from the nutrient solution prior to flowering. In a drain to waste system this event can be seen by a sharp drop in outlet PH. The problem in a recirculating system is you may not be aware a lot of the potassium in the solution has been removed by the plants. The PH drop is less pronounced in a recirculating reservoir but in any case most folks would likely just add potassium hydroxide (PH up) to raise the PH when they should replace the reservoir to correct the elemental imbalance.

mowed tree leaves is the key to good gardening soil here in Loveland as well. Such a wasted resource.

Teacher, I'm so glad you are a youtuber! That is so cool. I was wondering if peat pellets instead of rockwool plugs would work in this foam kind of system. Did you ever try?

Beautiful garden in such a small area!

I agree, "it is time to take care of the farmers."

Great idea that I am going to try, double bird netting to reduce the hail hitting the plants. Thanks!

How many harvests do you think you will be able to get in total?
