The Green House Seed Co.

Grow rate: flawless, node/week Water + Bio RootBooster pH 6.5 Mars Hydro: 1 x FC 6500, low consumption, dimmer switch 25% at 100cm ________________________________________________________________ I grow with passion, Cannabis is all my life … Like the Green House Seed Co. it’s all about a story of passion for marijuana plants https://youtube.com/@greenhouseamsterdam

14/08: Water pH 6.5 19/08: Bio RootBooster + Bio 8-2-2, pH 6.5 Mars Hydro FC 6500 x 3: Dimmer at 25% Overall growth rate is really fast. Green House Seed genetics are doing great under the Mars Hydro. Needed to spread the plants and to switch on 2 more ramps.

21/08: Topping all strains 24/08: Water pH 6.5 26/08: Bio RootBooster pH 6.5 Calibration pH pen buffer 7.0 Transplanting Mars Hydro FC 6500 x 3 at 25% Green House Seed Co. strains are extremely resilient, the plants suffered from a drastic lack of water, damaging some fan leaves on some few plants. Whatever, they recovered in 2 days without needing any skill, just by giving them a bath.

28/08: Water pH 6.5 Defoliation 02/09: Bio RootBooster pH 6.5 Mars Hydro FC 6500 x 3, dimmer switch at 25% Restructuring the plants at beginning of the week by defoliating all the fan leaves from the main stem. All plants were topped at the 3rd-4th node. Forcing the plants to rearrange their structures into small bushes in the early Veg stage.

09/09 Tap water non pH’d 12/09 RootBooster, 8-2-2, AllZymes pH 6.5 Mars Hydro FC 6500 x 6 at 25% The Genetics are definitely extremely resilient, I haven’t been able to take care of them during more than a week. I was planning some kind of SOG, but the plants are oversized now. This is actually their last week of Veg. Next update will be a Flowering Week. The main goal is to not cook the terpenes, Indoor it’s better to anticipate the space left for the stretch.

16/09: water pH 6.5 19/09: Bio RootBooster, Bio 8-2-2, AllZymes, Flower Stimulator pH 6.5 Mars Hydro FC 6500 x 6 at 50% The growth rate is impressive. There’s almost no space left in the room. There’s 27 plants in total, all differents genetics from The Green House Seed Co. Every plants are doing perfectly well on itself, I just need to defoliate some few leaves. All plants legs are cleaned from the small shoots and leaves, everything must go to the top now. Loading the plants with an organic 8-2-2 since last week, preparing for the stretch. It should start during next week.

23/09: Water pH 6.5 26/09: Bio 8-2-2, AllZymes, Flower Stimulator pH 6.5 Mars Hydro FC 6500 x 6 at 50% Ladies and gentlemen, welcome to the Jungle Cannabis Expedition, years of strains hunting from the Green House Seed Co. all in one place 😊 I can barely move in the room, watering this jungle by hands takes about 3H. Plants are sucking water like camels, they need 3 to 4L every 3 days, watering all the plants requires approximately 200L per weeks and 6H of work.

29/09: Water pH 6.5 03/10: Bio 8-2-2, AllZymes, Flower Stimulator Mars Hydro FC 6500 x 6 at 50% This is going totally insane 😄 The genetics of the strains are perfect. Every plants has a strong and healthy roots system (see pics). I wish I could push the walls and the ceiling to get just a bit more space. However, I gave them one last feeding with Nitrogen and will start the P-K next week to avoid any Die-Back around week 5 of flowering, despite all I feel like 2 - 3 of them will still have a lack of Nitrogen.

06/10: water pH 6.5 10/10: Bio Bloom, Alga-Max, AllZymes, Flower Stimulator Mars Hydro FC6500 x 6 at 50% Switching to bloom nutrients, boosting the P-K levels with the Alga-Max. Overall the plants are doing great, as I expected 2-3 plants are showing a lack of Nitrogen, but unfortunately at this stage of the growth there’s nothing to do about it* ( *week 8 ). The flowers opening is nearly finished with the majority of the strains, the plants started the swelling for most of them, the smell is getting really strong from now on. Trichomes started to show up slightly, next week I should be able to get some fresh THC and making sticky’s joint 🤩

14/10: Water pH 6.5 17/10: Water pH 6.5 Mars Hydro FC6500 x 6 at 50% Turned on 2 x dehumidifier, able to extract 40L/24H each. Lowering the humidity level to maintain it below 50%, to avoid any bud rot. Plants are doing well, got some few leaves tips telling me they don’t need any nutrients for this week. Buds are starting to get bigger and bigger, there’s still another 3 more weeks for the first ones before being ready to harvest. Other few plants are still moving their Nitrogen from the bottom to the top* (*week 8 and 9).

20/10: Bio Bloom, Alga-Max, AllZymes, Flower Stimulator pH 6.5 24/10: Water pH 6.5 Mars Hydro FC6500 x 6 at 50% Last week for the Alga-Max (P-K Booster) and the Flower Stimulator. Overall, the buds are fattening on most of all strains. Maybe except the Big Bang that might need more time. The White Widow are taking their time, developing buds slowly but surely like a proper White Widow strain does. Next week I will start to lower the amount of nutrients, using Bio Bloom and AllZymes only.

27/10: Bio Bloom, AllZymes pH 6.5 31/10: Water pH 6.5 Mars-Hydro FC6500 x 6 at 50% Reducing feeding solution to half strength for this week, and stopping the Alga-Max ( P-K booster ). Plants will get water only from now on, to make them break down the nitrogen ( chlorophyll ). Green House Seed Co. cultivars are absolutely fantastic. Strong genetics is primordial to be successful when growing Cannabis.

03/11: Water pH 6.5 07/11: Water pH 6.5 Controlled hydro stress: 3L / Plant Mars-Hydro FC6500 x 6 at 50% I can hear jingle bells ringing 😊 Arjans Strawberry Haze is ready for harvest. The Ztrawberry will be just behind. Others plants needs a few more days to break down their nutrients, there’s still some Nitrogen left in some of them (green leaves). I will definitely recommend Green House Seed Co. cultivars. From seeds to harvest the genetics are vigorous and resilient. They survived and recovered from a drastic lack of water at beginning of Veg and didn’t mind to be watered using non ph’d tap water by the end of Veg, they’re suitable for new growers and will forgive mistakes.

10/11: Water pH 6.5 14/11: Water pH 6.5 Precision stress: 3L/plant Mars-Hydro FC6500 x 6 at 50% Most of all the plants are nearly done breaking down their nutrients. Harvest has started with the fastest ones like the Ztrawberry and the Arjans Strawberry Haze. Others plants needs just a few more days before being harvested. RH is oscillating between 45% to 50%, 10 plants have been harvested and no signs of buds rot. Green House Seed Co. cultivars are definitely recommendable for any types of growers. Harvest reports will be following this last week of Flowering. Thanks to all for the kinds words in the comments, particularly the good ones who followed this crop from seeds to harvest, it was very fun 😊

All pheno. grew identically and turned into making deep purple flowers.

Both plants developed very well. One of the phenotype stretched x 2.5 in size in bloom and grew extremely fast in Veg making longer internodes.

1 pheno. is more compact than the 2 others. One or another, bot pheno. produced approximately the same quantity. The stretcher’s will show a fast and vigorous growth during Veg.

Growing this strain since decades, proper genetic from the 90´s it hasn’t change since all these years. It grows slowly and stays short with plenty of dense buds.

The strain grows fast in Veg and doesn’t stretch too much in Flowering. 1 phenotype is just a bit smaller than the 3 others but the harvest was about the same for all plants.

The plants grew fast in Veg without stretching too much in Bloom. Developing many dense buds sites. Great genetics suitable for indoor growing.

Very fast and vigorous growth in Veg, would be perfect for ScrOG. With a x2.5 stretch in size during flowering. Produce tall buds and will require supports.
