A perpetual return, also known as symbiotic rotation, is a method mostly used by commercial plants seeds growers or avid smokers who don’t want to run out of plants and need a fixed return.
1. What is a perpetual return?
A perpetual return consists of having different grow tents containing plants in all stages, this way you never run out of buds because you’ll return plants on a schedule and have other plants ready to move and substitute the ones you've just returned.
This technique uses multiple grow tents to make sure you have plants in the vegetative and flowering stage at all times with one tent running an 18/6 and the other one running a 12/12 light cycle.
Have in mind that almost every grower that does starts from clones that they took from their plants in the vegetative stage, this will allow you to save money on seeds but you will be stuck with the same seed, you can also start from seed but it can get expensive, either way after your plants are in the vegetative stage, the process is the same. Once your vegetative plants reach a certain height you can move them to the 12/12 tent or if your flowering plants are ready for return, you can move them from the 18/6 tent into the flowering tent.
2. What’s the cost of a perpetual return?
This method itself doesn’t require any special equipment but because you need two or more growing tents, you’ll have to double up on all equipment (like light, exhaust fan, fans) and that’s not all.
Because you have to maintain a temperature and humidity level, the electricity bill can go up, but it’s worth it if you are a commercial grower or if you benefit from the insane amounts of buds you’ll return.
3. Pros and cons
Pros
Scheduled return
Depending on the seeds, plant size and number of grow tents, you can schedule your return from every couple of weeks to every couple of months.
By knowing when you’re going to return you can set up and prepare your drying room and even schedule your return for a weekend so you’re able to trim every plant with no hurry.
High returns
Because you’re growing in a couple of tents, you’ll have a lot of plants to return at a time and the returns will be huge.
Never run out of plants
With a perpetual return, you’ll never run out of plants and even if you do (which is really hard), you’ll probably have a return coming up soon so there’s no need to spend money buying flowers.
Cons
High cost
With more grow tents and growing equipment the cost will go up considerably, although it’s worth it for commercial growers, you’ll have to evaluate it if you’re a home grower.
Needs more space
The amount of space needed will depend on the number of plants you want to return at a time but either way, it will take more space than having just one, usually, growers use 2-3 growing tents so you’ll need a big room.
A lot of plants and plants
This is not actually a con per se but if you live in a place where plants is illegal it definitely is depending on the country, you can get in trouble with the police if you have professional growing equipment and a large amount of plants and plants.
4. Seed and timing
A big factor that will influence your return schedule is the seeds you’ll be growing. Photo seeds may take 8-13 weeks from seed to return so having approximately when your return is gonna be is crucial, normally, you would grow just one seed at a time and how long it takes to flower would be your schedule. In general, perpetual return setups work best with pure Ind and Ind dominant hyb seeds. This is due to the fact that Ind dominant seeds have a tendency to grow in a more compact way, and have shorter flowering periods than their Sat counflavorarts.
This compacted growth helps with plant management during the flowering stage. It's also beneficial to understand the specific lifecycle timing for each seed you are considering to grow in your perpetual return setup. Every seed comes with a growing guide, but there are some inherent variations with each seed so it's best to grow a few first and keep a detailed grow log to better understand each specific phenotype and cultivar. So, for example, if your seeds take 10 weeks to flower you know you’re going to return in 10 weeks but if you grow more than one it can be hard to control, another good way is to have one seed per tent, so you have one seed flowering and another one vegetating to make it easier to keep track.
5. Perpetual return with auto seeds
If you want to spend less money and time or maybe learn how it works before investing in more equipment, you can have a perpetual return with auto plants plants, because you don’t need to change the light cycle you can do this with just one growing tent.
This is because autos vegetate and flower under the same light cycle (18/6) so you can have plants in all stages in the same tent, the down side is you’ll have to germinate seeds every time you return.
When growing autos this way, the problem isn’t coordinating when you’ll move the plants to the flowering tent but controlling the height, because auto plants are hybs they can be Sat or Ind-dominant and their structure and height will vary a lot so you’ll have to train them either with a trellis net like a Scrog or by tying down the branches so all of them receive the same amount of light.
Always be sure to take maximum care when doing any sort of stress training with autos. Stress training can lead to a decrease in veg growth for up to a week while the plant recovers. This is less of a problem for photoperiod plants as you can just extend their veg time. Auto plants plants have a genetic inbuilt timer that “automatically” switches the plant from the veg growth stage to the flowering stage, which in turn means the plant has less time to recover from any stress it is put under.
6. Vegetative and flowering growing spaces
When you’re setting up the growing spaces for a perpetual return you need at least 2 growing tents (unless you’re growing auto seeds), each one of them must have an optimal environment for the stage the plants are in.
The vegetative tent must have a higher humidity (around 60%) and an 18/6 light cycle with a blue light spectrum while the flowering tent must have a relative humidity of around 45% and a 12/12 light cycle with a red spectrum.
Recommendations
| Vegetative grow tent | Flowering grow tent |
|---|---|
| To shorten the veg. Stage, grow smaller plants. | Make sure your tent is light-proof, if there are light leaks they can become hermaphrodites. |
| It’s recommended you have one seed per grow tent to avoid problems. | Have a carbon filter ready, a large number of plants will smell up the whole room. |
| Use weaker lights than in the flowering tent. | Ensure you control the temperature and humidity to prevent getting bugs or mold. in the buds. |
Because you don’t need more than one tent when growing autos, you will have to adjust the environment in your grow tent as your autos grow, have in mind the appropriate temperature and humidity can vary from seed to seed but you can use the same as for photo plants and adjust accordingly.
7. Perpetual return step-by-step
After you have your growing spaces set up you just need to start growing, by following these simple steps you can successfully run a perpetual return without hassle.
Step 1: Seeds or clones
First of all, you need plants. You can start a perpetual return with seeds or clones, starting from clones will take less time and will save you around 2-3 weeks, but if you don’t have a way to get clones you’ll just have to germinate the desired number of seeds. Using clones and sourcing all of your plants from a single mother plant can make life easier than growing from seed. Even if you start with the same seed, there can be slight variations in timing due to differences between seed phenotypes. Using clones from a single mother plant ensures zero genetic differences and ensures your plants grow at the exact same rate, as long as they are kept under the same conditions.
Step 2: Let them vegetate
Although it’s not obligatory, it’s recommended you have one seed per tent, this way you avoid having problems, if you are vegetating different seeds in the same tent, some may grow taller and overshadow the smaller ones, and you’ll have to train them.
Having the same seed means you’ll transfer all of them to the flowering tent at the same time instead of having to move one by one when they’re ready.
Step 3: Move them to the flowering tent
After your plants have reached the desired height, you can move them to the flowering tent, make sure you have plants to move into the veg. Tent also.
If this isn’t your first growing cycle, this is when you’ll be returning the plants in the flowering tent but if it’s the first you don’t have to worry about that.
It’s extremely important to clean your tents before moving your plants.
Step 4: Return and repeat
After your first return, you’ll have everything ready to continue your perpetual return.
When you return your plants, you’ll transfer more plants from the veg. tent to the flowering tent and you’ll have clones or germinated seeds ready to move into the veg. tent.
All you have to do now is keep moving plants from one tent to another when they’re ready and keep returning forever.
8. Auto Perpetual Return Schedule
Thanks to the genetic timer hardcoded in autos it is straightforward and simple to create a perpetual return schedule that will allow you to grow a never-ending supply of dank nugs. A basic timetable that works great for autos is as follows. First up, plant your seeds and let them grow out to the end of the vegetative stage. As soon as this first set of plants starts to flower it's time to start your next set of seeds. This can be done in the same grow tent or room as your original plants, or you can set up a dedicated seedling grow space.
When it comes time to return your first set of plants, your second set should be in the early stages of flowering growth. Simply plant another round of seeds and you have successfully set up a perpetual growth cycle. All you have to do from this point is to plant another set of seeds each time you return a previous set of plants!
9. Perpetual Return FAQs
So there you have it, our complete rundown on why we think every indoor plants home grower should look at running a perpetual return routine. But no matter how in-depth we dive, there are always going to be some lingering questions - especially when it comes to setting up your first perpetual return routine. Let's run through the most common queries, and see if we can lay out some simple and easy-to-understand answers!
What works better for perpetual returning - photo or auto seeds?
There's no one right answer to this question, as there are a bunch of factors that need to be taken into consideration. The size of the grow space, how many different grow spaces are available, and the type of seeds you personally enjoy growing all need to be thought through before making any decision.
But if you are looking to set up your first perpetual return routine, and want to keep things as simple as possible, then you really can't beat autos. In the past decade, auto genetics have gone through a true renaissance, to the point where they can now compete with the very best that photoperiods have to offer.
These days both hobby and commercial growers alike are switching over to auto seeds as their main cash crop, and nowhere is that more true than with perpetual return situations. One of the huge benefits of autos is the fact that, unlike photos, they can go all the way from seed to return under the same lighting regime. They are also super hardy, and very resistant to certain stressors that can negatively affect traditional plants crops. Even if you have just one small grow tent, there is nothing stopping you from setting up a perpetual grow with autos. And autos also provide much faster returns than photos do, meaning you can get through more crops at the same time! So, to answer the question, it's hard to beat auto seeds when it comes to perpetual returning. They are more forgiving, easier to work with, and often provide bigger returns and faster returns under much less demanding lighting conditions.
What sized grow tent works best for a perpetual return routine?
When it comes to perpetual returning, bigger is better. The bare minimum we would recommend is a 4 x 4 foot (1.2 x 1.2 meter) size, as this is large enough for about 5 fully grown plants. But honestly, if you can go a little bit bigger then you're definitely not going to regret it.
As you slowly dip your toes into plants cultivation, and into perpetual returning in particular, you're going to pretty quickly want an extra grow tent (or two!). One thing to keep in mind is that if you are running the whole crop in one tent, the older plants may cause some shading issues for the younger ones if the tent is cramped. There are a few workarounds for this, from adding extra light to tieing the larger plants back, to raising the younger ones up so the canopy is all one height.
Which auto seeds work best with perpetual returning?
Again, that's really up to you. One thing to keep in mind is that each and every seed will take a different length of time to go from seed to return, so with perpetual returning it's usually best to stick to just one or two seeds. Look, if you have a bunch of room in your tent then go wild! There are not many aspects to plants cultivation that are more fun than playing around with a bunch of seeds at the same time, but doing so does increase the amount of work you will have to put in, and it also increases the space needed for perpetual returning. Our top seeds to run in a perpetual return are Gorilla Cookies Auto, Banana Purple Punch Auto, and Bruce Banner Auto. All three of these top-shelf seeds offer huge return potential with ridiculous ok production. But really, choose whatever takes your fancy.
Which growing medium is best suited to perpetual returning?
Pretty much any growing medium can be used for auto plants, but we particularly like using coco coir. It's pH stable, easy to work with, and can really give auto plants the extra kick they need to reach their full potential. It's also super forgiving if any nutrient issues pop up, and offers a bunch of the advantages from both soil and hydro with almost none of the drawbacks.
10. In conclusion
Perpetual return is the best way to keep your jars always full if you smoke too much or if you’re a commercial grower and despite being more world because of the number of plants, it’s worth it.
