Ever use FoxFarm soil?
Absolutely, the Ocean Fox Farm is a little hotter then the Happy Frog Fox Farm even though the Happy Frog bags are a little bigger.
If you want buds that weigh over an ounce each use the Ocean.
the trichomes and when they turn from brown to clear, its the height of theTHC level.
Actually the height of the THC is when the head of the trichome has a big clear ball on it that just before it starts turning color. IMO
They make charcoal exhaust system that block 100% of the smell if you want to spend the money.
In the old days the plants that were grown outside with that Afgany seed produced over a kilo per plant.
The plants were like 13 - 14 feet tall.
Spending a few extra on bulbs isn't going to make a huge difference
Obviously you are a novice as you are totally wrong.
In vegetation to start a "Grow" Metal Halide bulb (first six weeks at 18 hours a day) is designed with sunlight spectrums that will not only stack the limbs closer together to make your plants very bushy so you don't have Charlie Browns sparse Christmas trees. FACT.
The brighter the better and the bulbs designed for it's purpose is well worth the extra money.
You are a business man and know what MOR is. (Money On Return)
So you spend an extra $100 on good bulbs and they produce six to eight ounces of one ounce sticky buds per plant compared to two or three skimpy buds with workshop bulbs. (Money well spent)
And don't start your clones to close to the plant or you will burn them up. Those halide bulbs run very hot.
Then in the last six weeks you flip your timers back to (12 hours per day) and use a High Pressure Sodium bulb that is designed to have the sunlight spectrum of the blues and reds that the Halide lights don't have.
These colors are need to make those big heavy buds.
It is a twelve week process from start to finish if you know what you are doing.
So I hear from my friends that have grown under lights for fifty years anyways.
I know I wouldn't begin to take the chance to grow in Poland with such laws.
