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.

I filled about half a room of my apartment with the tents and equipment.

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.

The Pro Grows: Blue Gelato by Barneys Farm – The 100l experiment

Why you should grow Blue Gelato 41

Derived from Thin Mint Girl Scout Cookies and Blueberry the Blue Gelato is another US based import to the European market under the distribution of Barneys Farm. The strain contains that mainly sweet and citric taste that Gelato is known for. Underlying with OG and Blueberry flavors you will get a …

(here I rolled a fatty to experience it another timer)

38°C on my balcony. The wind feels like a desert or caribian breeze. It all started with the selection of the particular flower. I decided to use one of the many top headbuds. The curing process was only three weeks in, the flower was as gluey as it gets and showed an incredible trichome density.

The effect delays into the second or third hit, subtle first but exponentially transforms to a truckload into the back of your head very quickly. The high is longlasting and top heavy. Side effects for me are a dry mouth and a big urge to eat some hot and spicy food.

The Grow

Germination and Seedling Stage

When growing from seed you should always germinate more seeds than the actual number of plants you want to grow. Since I wanted to have one single huge plant I germinated two seeds and simply used the first one to show up as the main plant.

After about 0.5 cm of the initial root showed up, I put the seedling into a 3 gal smartpot with a fresh batch of BioBizz Lightmix. The first two weeks of a grow are always slow and boring: You dont really need to do anything but sit and watch. I kept the soil moist with my sprayer to prevent the seed from tilting from too much water. After the stem was strong enough, I turned to my usual watering schedule. This is also the point where I first give the seedling external nutrition. Lightmix already comes with a good amount of plantfood but for the remainder of the vegetative I gave her 2 ml of Bio Grow and 2 ml of Bio Heaven per liter of water. As usual I lowered the pH of my water dwon from 7.8 to the region bewtween 6.2 and 6.5.

Vegetative Stage – the long training

As you might know, I count the seedling stage into the veg stage. So the day my seeds get hit with water, I start counting veg days.

After 18 days the plant was ready for the top. I topped her once with intend and a few times by accident. I topped the plant right above the second node, so I ended up with four main branches, that will be trained outwards.

Training setup is done! For the rest of veg I just had to train the shoots outwards again and again. four weeks into vegging I transplanted the plant into its final container: A single 100 liter unit! I decided to give her eight weeks to root through this volume.

For this particular plant it was necessary to remove several side branches while it got trained further and further. The internodial distance was just to short, and even with this premeasurement the plant ended up being a nasty bush nontheless.

I wanted to play that out as far as possible and ended up with a structure that looked more like a weird piece of art than a plant.

The branches and the stalk are getting fatter by the day after 8 weeks of veg. The plan was to let her grow to the walls of the grow room and then upwards to encourage a bit of stretch once shes sent into flower.

A few words why this method of growing cannabis is actually pretty dumb: So my grow room would be on top when it comes to economical grows. I use very efficient LED lights and do not bother with AC units or anything that impacts my electricity bill alot. I am still growing with under 400W of total power. But having a plant in this environment for that long kind of kills the idea of being economical here. Time is an important factor when it comes to economical growing, and what was done here was the opposite. The grow itself took close to 5 months to finish, while its possible to harvest more in just 3.5 months.

Flowering the beast

After 84 days of veg I pulled the trigger and started flowering. The branches did not really hit the walls of the grow room, but I thought the flowering stretch and a little bit of spreading would take care of that. Note that I defoliate pretty conservativley before flowering, which cant be seen here exactly, but my goal is, that every top gets direct sunlight.

But I was wrong here: the plant had to support about 50 to 70 tops and stretching was not something she wanted to take care of. My assumption is, that the potential to stretch decreases heavily with the amount of top to put energy into to stretch. I got about 5 cm extra height overall, and thats it.

With the development of flowers, the plant now needs different supplements. So I switched from grow to bloom nutrition according to the BioBizz nutrient schedule sheet. I watered the pot with 10 l of water every 3rd or 4th day. Hitting day 21 of flowering I went for another round of defoliation, but I figuered out soon enough that this would not be enough for that lady. She kept putting out leaf material by the day, and I could grab handfuls of leafs far into the flower cycle. Most of the leafs on the back of the plant could not be pruned because I simply could not access that area at all…

Whenever you hit week six of flowering theres not much to do but checking trichomes and soil moisture.

Although I had to deal with leafy colas the resin production on that strain is insane! After only 20 days of flower the colas were packed with trichs and after only 46 days I could already see trichomes turn amber.

Harvest, Drying and Curing

So after only 57 days, six days before the harvest window given by the breeder, I decided to cut her down. Not only because she was ready, but I had to fight high temps in the grow room, and I did not want to risk any mold since that bush was so dense! pulling out a 100l pot out of that room was a pain.

I decided to dry trim this time. So I cut away most of the fan leafs and hang her up branch by branch. After 7 days of this initial drying it was time for manicuring. This is mostly done by removing everything thats not flower material. But since the resin production of that one was so incredible dense I decided to keep a lot of sugarleafs on her. It was a rather experimental run in the end and I would not do it like that again, but a worthwhile experience!
