Slick setup man, I'm excited to see a hydro scrog from start to finish. Is there a reason so many ppl choose soil over an EBB + flow or bubbleponics type system? To me it seems like the hydro's are actually a little more forgiving to a new grower, so easy to test PH and nutrient levels.
Can you give me any insight on the advantage of EBB+ flow vs a bubbleponics system? I understand the control bucket and reservoir are nice to have, but do these significantly cut down on maintenance time?
Sure I can give you some insight--at least from what I know haha. Since I'm a firm believer that the advantages of the ebb n' flow system beat other methods, I can explain why I use it and what I like/don't like about it.
Soil vs. Hydro
I'm not really sure why so many people stick with soil. I know it's a lot more forgiving, and definitely advantageous to new users. If you fuck up in hydro, all of plants are fed incorrectly or get something toxic, especially because the medium isn't as forgiving as soil. Soil is also the natural and organic way to go, and bud tastes better out of these systems. There's a lot to say on the subject but the main thing to mention here is the fact that in hydro systems you have a lot more control over what your plants are being fed nutrient wise, but it is WAY less forgiving. It's a lot easier to harm your plants if you don't know what you're doing, and you can go from having great plants to dead plants with one simple mistake. It's just more advanced and complicated than soil setups.
Now onto the bubbleponics/DWC vs. Ebb n' Grow
Bubbleponics
Bubbleponics has a lot of major advantages, but I'd say the main benefit of using this system is the ability to grow plants quickly. For those that don't know, "bubbleponics" is just a fancy word to describe a top-fed Deep Water Culture (DWC) hydroponic system. The roots are allowed to hang without a medium in order to get the best access to water, oxygen, and nutrients. Because cannabis needs high levels of oxygen in their nutrient solution, bubbleponics is effective because it is constantly moving to dissolve as much oxygen in the water as possible.
I have never used a bubbleponics system, but I know people that do. When I decided to use an Ebb n' Flow system, I considered these disadvantages of the bubbleponics system:
- A full bubbleponic setup can be a bit of work to get set up
- Because your cannabis roots are growing directly in water, you are more likely to experience problems with root rot and other types of root problems.
- Requires a great deal more attention and maintenance. You must clean your system frequently, or your drip system will clog with salts from the nutrients and lead to dead plants
- If you lose power, you're fucked. Nutrients can't be flooded to your nets and the airstones can't provide oxygen to the solution
Bubbleponics or a DWC system is great, and the growth you experience is better than any other system. Plants simply grow more quickly in this system.
Ebb n' Grow
My system of choice as I explained previously. It's dead-nuts easy to use. Because they have no small tubes or tiny drip apertures, flood systems can't clog and can be cleaned and sterilized completely in 10 minutes. As I said earlier, you can get slightly better performance out of fancier systems (although the difference is marginal). On the other hand, the simplicity and reliability of a flood system is second to none and the maintenance levels are a lot lower.
The portability of this system is also another big draw-to. It's extremely mobile, and the buckets can be moved around at the growers leisure. Buckets can be lifted and moved, even transferred to different rooms (if you have separate veg/flower rooms). It's also very easy to expand the ebb n grow system. More buckets can be purchased and included in the system with very little work--they all run off the same res and controller bucket.
In addition, because the nutrient solution is released into the buckets at time intervals, the roots don't sit in water (like they do in the DWC system). This makes it easier to control root rot and other nasty root issues. And if for some reason you do have an issue with root rot, the problem is isolated to a single plant and not the entire system.
When the timer on the controller bucket signals a flood cycle, water is pumped into the controller bucket and gravity forces water into the individual buckets used in the system. Water and nutrients are supplied to the plants (without the use of a pump or electricity), and when the allotted time is completed on the flood cycle, the solution then flows out of the buckets and back into the controller bucket where it is pumped back into the reservoir. As the water moves out of the system, air is sucked down into the medium (and to the roots) and this is how the roots are supplied with the vital oxygen that they need. This is a major advantage, because oxygen is supplied in heavy doses after each flood cycle, which is right when the plant is finished feeding and needs the oxygen most. The whole system is very simple, yet extremely effective and virtually maintenance free. The resovoir just needs to be changed every week/two weeks.
Also, with a SCROG grow like the one I'm doing now, It would be a lot more difficult to change the res on a bubbleponics system. My reservoir is separate and located outside of the system because the plants don't physically grow INTO the res on an ebb n' grow system like they do in a DWC. I can't really lift the buckets now that they're through the screen, so to be honest I don't have a clue what's going on with their root systems lol (I guess this could be a disadvantage), but from what I can see of the plants their roots seem to be doing just fine.
Pic of my res:
I know you probably knew most of this already, but I put it in simple terms and explained both systems to those that aren't experienced or to help answer future questions. Hopefully this is the answer you were looking for, and if you still have questions please ask away! I tried to answer it to the best of my knowledge, but I really only have experience using one system. I'm sure there is a lot more out there (maybe others can weigh in), but this is what i know!!!
Take care,
