Consider Bubba’s gift from Humboldt seeds. 6 weeks flowering and nice purple hues

Im growing Bubbas Gift this season and it hasnt started to show sex yet. Just hope its done before the 1st week of October. Weather in the North East US can get really crappy in Oct . Anybody else out there have experience with this strain?

Speedy Chile fast by royal Queen is the fastest I’ve heard of. It’s finished in 56 days from germination and only needs 14 days veg. 16% Thc. Fem photo 80-100cm tall and 500+ grams per m2 indoor. Critical poison fast should be on the list too. Finished in 40-45 days 18% thc Fem photo 500+ grams per m2 indoor.

HI bro, how many plants per m2 can u grow with these??

Wow. This is a real treat for both the consumers and the farmers. Personally, I like Green-O-Matic Auto. It sorts of suits me. Thanks a lot for sharing.

Pineapple Express #2 from G13 Labs all day on my 3rd run with this strain and I have more chasing it

Bro, i have a special pheno of her, been runnin her for like 4 years now.. Its amazing what she does in just 50 days… I like to run an extra 10 days though…

got some free seeds from just cannabis seeds and so I thought I would throw a few of them in the dirt, only one was fem and a hearty little sativa that I topped 3 times for max yield and about 45 days in it looked like I was well on my way to getting 1/2 lb off of her when the buds fattened up in coming weeks considering I had about 4 more weeks before harvest, but just for fun I thought I would check the trichomes at a time I felt was early, and WTF. I’m sitting on 15 to 40% amber and no clear trichomes, in 45 days, on a pure sativa!! Well my yield wont be as big but its an early surprise. Wish I would have cloned her,

Just leave a couple small buds and regenerate growth after your harvest.

Known for a heady high that isn’t overwhelming, this is a great Sativa-dominant hybrid that won’t stop your day in its tracks.

AK47 is a lot less threatening than it sounds – if fits of giggling and increased creativity are prized effects this may just be your new jam!

This is a highly-popular strain, with a lovely mix of effects than tend towards the Sativa spectrum depending on the plant.

It has multiple genetic variants; typically the auto-flowering variety is known to flower the fastest.

Keep in mind one drawback is that AK47 is not a predictable yielder; final harvest is heavily dependent upon environmental factors too.

Don’t let that put you off – many people have been successful in growing this strain and the bud it produces was good enough to win multiple Cannabis Cups!

Often ready to harvest in mid-September, AK47 is another great choice for early flowering crops!

Famous for a strongly-cerebral high, LSD earns its name for effects that vaguely resemble those of the famous psychedelic.

Don’t worry – this plant is all THC; however with a 24% THC level it’s certainly one to be approached with caution.

LSD plants are hardy, strong and don’t require a high level of maintenance and care.

They do require light and warmth however, so a sheltered area or the use of a wind-breaker is best for cooler climates.

Another strain that harvests very respectable yields in mid-September, LSD is a go-to for growers who have a short but warm summer!
