3 Pflanzen - 1 Topf / Experiment #1

Here I want to see if I can maximize the yield by growing 3 plants in the same pot. I am using Plantaflor Cannabis All-Mix as substrate and the Terra Aquatica Bio Palette as fertilizer. Additionally, I’m using CalMag from T.A. The 3 plants are 3 feminized Gorilla Sherbet from my own production. They are currently 35 days from germination and 14 days into the vegetative stage. Today, I first drilled some additional air holes in the final pot.

Afterwards, I planted the three seedlings and watered them with 2 liters of water. Trichoderma and 1 ml of T.A. Grow fertilizer (half of what the manufacturer recommends) were added to the water.

The light has a distance of 30 cm and runs with a power of 60 watts, lighting duration 16 hours. Temperature is at 24 °C and RH was at 45% (still rising).

I will likely keep them in vegetative growth for 2-3 weeks before switching to flowering. During that time, I will string up a net and fix them to it to fill the tent (60×60×160).

3 plants one pot will diminish yields. 1 plant would yield you more. Not to mention things like defoliation will be harder yet more important. Overall it’s a fun experiment but a waste of 3 seeds.

Since I produce my own seeds, they cost me nothing, and they don’t last forever.

In Ed Rosenthal’s book “Marihuana Growers Handbook,” I read something about increasing yield; he writes:

1 Plant = normal yield

1 Plant topped (8 shoots) = more yield

3 Plants 1 Pot = maximum yield

I will soon stretch a net and fix them to it. In this way, I will try to fill the entire tent. We will see the result in approximately 14 weeks. The flowering period for this strain is 12 weeks.

Hey there @herr_gruen ,

It was almost

Main stem has turned red. Possibly stress-related from repotting or watering with water that was too cold. I have now placed a canister of spring water next to the tent so that it reaches room temperature until the next watering.

Two days after moving to the new environment, the lateral branches are starting to grow.

Today Grow Day 18 / Day 38 from Germination

Temp 23.7°C/RH 53%

The 3 seem to have slowly recovered. More side shoots are starting to grow and they are also increasing in height. There is enough moisture in the soil, so I probably won’t water again until the weekend so that the roots can expand to search for it.

Today I raised the lamp a bit so that I have a 30 cm distance. On the plant in the back left, you can already see the pre-flower.

First node below the tip

Room temperature is 22.7°C and humidity is 48%

Today WT 20

I’ve already hung the SCROG net. I have 15 cm from the top of the pot to the net, which should be sufficient, or rather, has to be sufficient due to the limited height of the tent.

Today there was another 1 liter of water, 1/2 liter from above and 1/2 liter into the tray (I could watch it being directly absorbed).

Pre-flowering has been visible on the second plant since today. The largest of the three is 20 cm tall, the other two are a bit smaller but not far behind. The side branches are also slowly getting bigger. Only the red stems are not changing, but that’s not a big deal. The green of the leaves is vibrant green.

RT 23.2°C / RH 48%

Today WT 23/ W4

Wasn’t home yesterday, and after 2 days, the three had changed beautifully again. The leaves and shoots have grown nicely, and the stems have become stronger.

Today, I lowered the net another 5 cm and attached the first three clips to pull the plants apart a bit.

RT was 25.3°C and RH was 60%.

Now I will slowly fill the net and switch to flowering either shortly before or when it’s full.

WT 25/ W4

Today WT 27/W4

Yesterday, the 3 plants together received 1.5 liters of water, half from above and half into the tray. Today, RT is at 22.3°C and RH at 65%. The lamp distance remains at 35 cm for now, and the power at 60 watts. This way they grow a bit slower, but the 3 have time to form more roots on the stem.

Here’s each one individually

Heute WT 30 / W 5

RT 21,8°C / RH 67%

Before

Today I was able to fix the first side shoots to the net. Afterwards, I removed the lowest fan leaves. A yellow sticky trap was also placed in the middle of the pot today; I’ve wanted to do this for a while but just hadn’t found the time to look for one until now.

After

That awesome shit would bother me; I already have too little space with my trail autopot system easy2grow. But I’ll stick with it, dude, let’s see what’s possible.

Today Day 35 / Week 5

Room Temp 21.6 °C / RH 68 %

Today I increased the lamp’s power to 120 watts.

The net is already pretty much full. I guided a few of the lower side shoots into the free space with LST clips and clamped the main shoots to the net again. A few side shoots were also fixed to the net.

Yesterday, before watering, I carefully pushed away some of the soil around one of the stems, and behold, a few roots were already emerging. Afterwards, there was 1.5 liters of water with T.A.Grow fertilizer and Trichoderma. The whole mixture was adjusted to a pH value of 6.7 and 20 °C. The first half was poured and the other half went into the tray.

How many days of veg did it take to get to this?

I had them on the windowsill for about 5 weeks and now they have been in the tent for 3 weeks. So, 8 weeks since germination. When repotting, I buried them up to the first serrated leaf because they had grown too long; that was a little over 10 cm of stem that has now formed roots.

They stretch like that bc they are not getting enough light. They’re saying I don’t have enough light and grow quickly to reach for more light. Increase the intensity by lowering the light or turn up the intensity by the knob. Either way will keep the nodes closer together.

The lamp hangs 35 cm above the tops and is at 120 watts in a 60 × 60 × 160 tent. In 2 days, they will go into flowering; I am already reducing the lighting duration. I need the internodal spacing right now to fill the net. If the nodes are too close together, I can’t attach any clips. The long spacing of the lower side shoots comes from them wanting to reach the light; yes, that’s correct, they will reach the light at the net, which is where they should go. From that perspective, they are doing exactly what they are supposed to do right now.

Clips are for use in veg during flower you just tuck under the trellis net.

Today is BT 1 /W 1 ( Day 57 from germination )

RT 24.7 °C / RH 46 %

Today the plants received 2 liters of water, the soil was already so dry that the leaves were drooping. Additionally, T.A.Grow fertilizer ( 4 ml ) was added. The water was warmed to 20 °C and adjusted to a pH of 6.7. Watering was done again half/half from top and bottom.

Afterwards, the three plants were topped so that all the energy goes into the side shoots. Additionally, I removed their large fan leaves (except for the top two) so that more light shines through and the air can circulate better.

Afterwards, I reduced the lamp distance to 25 cm, the power remains at 120 Watts for now.
