OK I grew some out last year

GreenHouse - Yes! Better pest control (IMHO) and you get better stealth too I guess.

I used organic ferts - Bat Guano in some regular compost. As the life cycle is so short you don't need to mad on ferts imho.

Watering - at first nothing really, just watch if its getting hot in there - during hot summer days you want to keep an eye on them and not let them get too hot. A decent amount of airflow is needed.

+ They STINK compared with Lowryder 1 : Be careful of this. The Brazil Indica genetics (Santa Maria) are the culprit I think.

Pots should be as big as you like - go deep as they still root deep. Small pots really make a difference imho even early on. This plant will be around for 100 days though so if space is an issue then maybe you could start with smaller 6' pots then move them after sexing.

They show sex at about 21 days

They WILL stretch and become not-so-low-ryders if they don't get direct sun. My biggest lowryder came out at about 23' well above the 12-18' you get indoor.

Yield is MUCH better with LR2 but its still low, expect 7-30g per plant but I recommend you grow some for seed as you can't clone the LR's.

The smoke is uplifting and rushy - a very nice stone. I though LR1 was nice - but LR2 is significantly improved.

I would like to try MiniGun ~ LowRyder x Ak-47

Hope this helps
