The original Tahoe OG Kush cut came from an s1 from in a bag of Chem91(Chemdawg) in the Lake Tahoe area in 1996. A s1 is a self-induced seed. S1 seed is made by self pollinating a female to create seeds, you can use gibberellic acid or silver sulphate to reverse sex of a plant to male, collect the pollen, and pollinate a female plant. The resulting seeds will be female.
OG Is one of the strongest cannabis strains in the medical marijuana community. THC contents have been tested to be anywhere from 24-28% THC. The OG grows very viney with big spaces between internodes. The OG loves feeding on calcium magnesium through out the vegetative state. One thing you must do when growing this strain is to let it veg out and super-crop. Many novice growers that attempt to grow OG result in low yields due to no low stress training such as topping or super-cropping. This is a plant that wants to grow strong for its environment so give it lots of speed bumps and physical training prior to flower.
Around the 6th week of flowering, progressively decreasing the nitrogen concentration, you want to up the levels of phosphorus and (P) Potassium(K). Week 8 you want to completly cut all nutreients and give your plants a nice flush until week 10-11 depending on how well your environment treated your plants. Week 10-11 should be the window of when you should harvest OG Kush strains.
Tahoe OG can now be found from The Cali Connection seeds. Said to be one of the strongest hitting and tasting medical marijuana around. The Cali Connection took their SFV OG Kush F3 male and hit the Tahoe clone (The "SFV" is San Fernando Valley). So far every seed that has been grown is pure Lemon kerosine skunk funk to the max. Let them go to 70 days flower and watch out , yeilds will be solid with good training.
