Growing Blueberry Autoflower Indoors – Step by Step Journal

Updated: Nov 1

The best way to learn how to grow marijuana is to start growing!

Late bloomers regret not getting hands-on experience sooner.

With the amount of research and materials online, it’s easy to grow cannabis inside your house.


Blueberry auto grow journal:


Sometimes, people become stagnant in researching.

They get overloaded and overwhelmed by too much information.

No amount of research can prepare you for growing. Even the most experienced growers run into unanticipated challenges.

This grow journal records the excitement of growing Blueberry cannabis for the first time!

Supplies:

  1. 2x4x7 Gorilla Grow Tent

  2. 2 Hyper fans: 8” inside, 6” outside

  3. P300 LED

  4. 5 Gallon Smart Pot

  5. FoxFarm Ocean Forest Mix

  6. FoxFarm Trio Nutrients

  7. Reverse Osmosis (RO) Water

  8. ILGM Auto Blueberry

Grower: Bassface Location: NA


November 5th

For the past 5 days, this seedling receives sprays of a gallon of RO water with 2.5mL CalMag. PH is down to 6.4.

The P300 LED light is at 36” away. The Hyper fans are also both set on low.

Seems like we’re all set! For first-timers, think in terms of mL, not cups.

There was a humidity issue inside the tent but it’s fixed now.

The humidifier was placed just outside the tent to let the intake fan suck humid air into the tent.

Within half an hour, the humidity went up from 25 to 45%.

Here she is! She looks quite happy after we hit the humidity sweet spot.

We may have an issue.

A few days back, the leaves and stems started dropping.

They’ve been fed with 3.75mL and 1.5mL of Big Bloom and Grow Big which were dissolved in half a gallon of water.

Every feeding, they receive less than a pint of the solution.

  2. THC levels up to 14%

  3. Great for in- and outdoors

  4. Delivers a relaxing high


This lone plant started flowering a week ago.

The temp has gone up to 80-85°F and humidity stayed around 40%.

Maybe the plant was stressed too much and hopefully, it’s just sagging temporarily.

Thank goodness! The droop was a mistake. It was just the plant getting bigger and heavier.

Every other day, the plant is measured and the light is always maintained to stay 24” above the plant.

That’s the recommended height in late veg and bloom.

She’s also receiving plain water now to keep the leaves perky.

This baby finally received her first mixed flower feed. Half a gallon of RO water was mixed with:

  1. Big Bloom = 1.75mL

  2. Grow Big = 1.25mL

  3. Tiger Bloom = 1.25mL

  4. pen Sesame = 1/8 tsp.

12 hours later, PH and PPM read 6.4 and 535 respectively.

Despite the normal findings, she seems to be drooping again. Winning is hard!

It’s time to flush to keep the plant from drooping. It started with15 gallons of distilled water.

She received flower feed mix with 2mL of Emerald Harvest Cal Mag. After testing runoff, the results showed PPM 350 and PH 6.7. She’s back in the tent now.


December 15th

24 hours after the flush, there’s noticeably less drooping in the leaves. She looks awesome!

It’s LST time! She received a little LST now that she’s 26 days old.

She recovered quite well. This should activate more nodes for a thicker growth!

The LST on her looks pretty awesome. The leaves have been dropping so it might be time for another flush.

It could also be a good idea to check the runoff to see where it’s at.

They look just about done. You can tell they’re all young-looking flowers with white hairs.

It looks like there are some clear trichomes but no obvious signs of amber yet.

Harvest may not be for another two weeks. The amber heads are just showing up over the last few days.

There are also subtle signs of nitrogen deficiency.

With this auto grow, it seems you should feed a transition feed throughout flower.

She hasn’t received any Grow Big through flower and that’s what seems to cause the yellow to take over the plants.

And in just over two months, it’s finally harvest day! This autoflower grow is mind blowing!

It only took a little over two months to grow.

These buds look juicy. And they also say you can lower the temperature and they will turn purple like the photo on the ILGM website.

These Blueberries are also known to change colors in the curing stage.

This one had signs of purple on the bottom side of the buds.
