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 …

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…

Resin production began early and heavily on that pheno.

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!
