Bumping this post.
The modern day gardener is growing in soil but watering hydroponically.
Soilless, soil, or in ground but watering  hydroponically. 
Many of you already doing this.
This is what I'm working on now for inside and outside gardening.
7-10 day reservoirs highly aerated or 1-3 day fill ups in warm weather.
The 1/4" connectors are to small and don't allow enough water flow and  pressure.
I'm already looking into using 3/4"OD for the loop with 3/8" line to the drippers for a shower effect.  I like to top dress nutrients into the medium and prefer shower dripper to wash it in.

The problem that I face with these mini indoor or outdoor drip systems is the pump and pressure.
In order to get a shower effect with some adjustable drippers 20-30psi is required.
Mag pumps that drop into a reservoirs connected to the main loop are less than 10psi not counting head, bends, length of mainline, and will only drip.
This meas that adjustable drippers need constant attention.
If the main loop  shifts, the water pressure changes and drippers need attention.

I went to the main source for drip needs.
Drip Depot understands what I'm trying to do and they are coming out with Centrifugal Booster Pump in 2019 that will generate higher PSI for these type of drip systems.
I find that drip feeding can run right through larger pots and waste the nutrient solution.
The other problem is leakage at the connectors indoors where the 1/4" connector pokes into the 1/2" loop.

I have seen growers use PVC main line into "manifolds" with grommets to connect the 1/4" drippers as a better option than soft water line systems.
They also use stiffer drip line 1/4" OD called Netfim and it's white to reduce temps in the system.

Also, timers are know to fail. They can turn on and not shut off and reset and do all types of crazy things and empty out a reservoir unexpectedly.    Trying to find an outdoor timer that does seconds or minute intervals is another challenge.

Not to get off the subject but now days growers are using  commercial drip mediums with drip systems.   
They cut back on the organics/TDS in the soil  and focus on synthetic nutrients and feed hydroponically. 
The medium drys quicker so the plants are fed more often 2-3 times a day indoors.

This is what I'm talking about when I say mass aeration in the reservoir. 
The ultra high dissolved O2 is an extra added bonus going directly into the soil.
No dead spots to reduce anaerobic bacteria in the reservoir. 
Add your nutrients and refill the water as needed. 
Easy gardening is fun gardening.

Update here.    Great White is decent product.  It is outdated however and packed with to many species  and some don't even benefit plants and they use clay instead of carbs.  
This product contains bacterias and fungi spores, a  2 in 1 product without any sugars for activation.

Hibiscus are considered a hardwood.
Endomycorrhizal fungi spores do nothing for hibiscus because Endo attach to the root and only benefit soft wooded plants like tomatoes and produce.

Hibiscus benefit from EctoMycorrhizal.
Ecto (think ghost) floats around soil and attaches to organic material like sphramnum peat moss waiting for a root to grow and attach.
There are some additives that contain Ectomycorrhizal but they are expensive and hard to find.

Sphagnum peat moss is an excellent way to incorporate Ectomycorrhizal into your soil.
Coco is dead and Ectomycorrhizal won't attached to coco, perlite, rockwool or other inert mediums.

Guys without mycorrhizal there is no life.   It is the middleman that takes nutrients from bacteria and passes it to the roots.
This is what I mean when i say garden with organics.
Photo below is from an organically grown softwood plant that i used Endomycorrhizal by dusting the roots, rootball, and the surrounding soil after I transplanted from a pellet to 4" pot.

Most of the mycorrhizal should be added during the early stages of growing and I recommend dusting  during transplant.   The spores are inactive until they touch soil or roots.

Great White is still beneficial to hibiscus but only the bacteria in the product.
The fungi spores are not for hibiscus since it's all Endomycorrhizal in G.W.

Worm castings contain bacteria from worms stomachs and some nutrients from their diet.
There are no mycorrhizal  fungi in worm castings.  Neither  Ecto or Endomycorrhizal. 




 
 

I stopped using all the Sierra products as don't use soap or oil products anymore.
I don't like the Sierra  program and if I'm going to spray something it better have nutritional value and kill all the bugs and continue working systemically.
It's way to expensive and basically buying water.

thanks Jim, I might not cut Padparadscha until the days start to get longer since she is going dormant.
I will keep you in mind thank you. 

Last year I lost Tsaritsa.  Winter 2017 I was going through last of the moving boxes and found a single bag of 1 seed marked Tsaritsa X Prom Queen 2014.
I will say the 2nd summer seedling not doing so well.
The flowers have been mainly 7" by my surprise and been lasting 3 days in 90F.      Prom Queen is somewhere on forum.
 I call the seedling Padparadscha pad-pah-raj-ah like the pink sapphire.  The untreated sapphire has purple hints.
Charlie can I send you some wood and ask you to grow it and see how it does?  It's on the  right track but winter is coming.  
A couple flowers this month from Padparadscha.

A tropical depression or remnants have parked over Ohio for 48hrs with 1 more night to go flushing.  Alota cool rain but  my hibiscus are  set up to handle it but at same time I can go a day or 2 in 90F without watering.  

Hello Kyle,  I think Padparadscha is stunning.  I would love to get a cutting or 2.  I have tons of root stock if all you have is woody cuttings.  It's a good idea to make clones of a CV you really like prior to winter.  My email is jimgroves132gmail.com   If you want to let me take a crack at it I'd love to.  Best of luck, Jim   

Purple rain, also pale due to being in the not so sun room in OHIO

A Pale Diamond Ring, yes we had to bring them in out of the cold.

Very nice photos.  Thanks for sharing.

I can never get enough of Island Queen, this year every single flower is at least 10 inches across and 5 or 6 high.  Gorgeous! 

First bloom off Blues in the Night.  Rocket Fuel keeps putting out massive flowers.
