The Farm – Perpetual cannabis growing at home

If you are growing at home for you personal use, you most likely own a single tent, a light (or two if you swap between veg and flower), some pots, soil etc. A single grow can be seperated into five different stages (0-4), and all of these stages take place inside that single tent. What if you manage to give every stage its own small room? This is called a perpetual grow. You swap tents respective to the stage your plant is currently in. Maximize your space and grow more efficiently.

Stage Zero: Cloning – The Greenhouse

For rooting cuts have a small greenhouse on the side. In this stage plants do not need ungodly amounts of light. I shine a small photolight or a desklight on them, to keep the clones from flowering. The rest of time I wait until I see roots emerging from the side and keep them moist. Not every new plant undergoes this stage, but seedlings can also be kept here if needed. Its also perfectly fine to put the greenhouse into a tent, if it has sufficient size.

Stage One: Clones, mothers, early veg – The Living Collection

The real first step into perpertual growing is seperating veg and flower. My clone tent happens to be a 2×2 tent for me with a cheap blurple light to keep things alive. In this tent I let my clones root through their pots and keep mother plants. Not much is happening here. Keeping everything green and vital is hard enough. The lights are on 18 hours a day.

The collection: This tent is always a bit chaotic. Everything that has to be kept alive is in here.

Stage Two: Vegetative tent – The Gym

Here it gets interesting: This is also a 2×2 tent, but with a much better light. I am using my Lien-Tec Dual Quantum Cube in here to get the plants used to the amount they will receive in the flowering tent. I also repot them into a 20l (5gal) pot, once they filled out their initial pot and let them root through. In this tent most of the plant manipulation takes place. The plants will be in here for about 4-6 weeks until they move on into the flowering tent. They get topped and LSTd, pruned and schwazzed in here, whatever you feel like doing to them.
My personal strategy: Get them to fill out their respective space twice, then cut away all but a single node on top of every branch three days prior to the flowering period and swap over new plants from the Stage-One-Tent.

Stage Three: Flowering – The Sunhouse

Where the magic happens: Every plant going in here is fully vegged, trained and ready to go. No timeloss here, everything is running at a 12 hour light cycle forever – no darkness periods or whatsoever. The plants in here most get spread abit with gardening wires or hooks. They also get the day 21 and day 42 defoliation and of course: water. But thats also basically it. Keep the tent clean! You will not have off-periods after a harvest to do that. So once a month, take everything out, get your antibacterials in here and clean your garden.

My current flowering tent runs on 6x CXB 3950 Cree COBs condensed into 2x Pro Emit Sunbars 150-B and 2x HLG QB288 V2. Totalling about 570W this tent is packed with light.

The beginning of a perpetual grow: Emptyness in the flowering tent. The number of plants will rise with time.

Stage Four: Drying – The Barn

This is more or less a small darkroom where 3-4 plants should fit in, drying. You are used to hang every thing from a tent inside said tent for the initial drying period. This is a huge off-time where your tent is blocked for veg/flowering purposes! My small IKEA-hack (article is pending…) involves a kitchen cabinet with wheels and a big hole on top to connect to one of the tents. This way you get a suction airflow, thats perfect for drying bud initially. The room does not have to be as big, since you only harvest 2-3 plants at once using that method. To dial everything in, you will need about 3-4 month of planning. In the first iteration you can even stat mulitple plants in each of the stages and cumulate them after a while in the flowering tent. This is your last step to perpetual grow: get drying out of the flowering area.

Useful tricks

Plan ahead

So with one single tent you have plenty of time to choose new genetics. In this operation you have to choose genetics about every two weeks, so be prepared! Work out a plan for several month ahead and stick to it. You will learn how the system dials in, and how long each plant can veg etc…

You can print out sheets of these calendar-pages to keep track of every plant. You can find them here.

Maintain a journal of everything

Once you gro perpetual, you will handle much more plants in every possible stage at once. They all have different needs. Keep track in what stage every plant is at the moment. Write down things like date of germination, date of switching stages, how many days they were in each stage, etc. Keep track!

Have fun!

With this perpetual grow method you should be able to not only keep more genetics in your operation but also have a steady refill of your stash instead of a massive haul every 3rd to 4th months.
