re: ChillAH's 1st BB X White Widow & Royal Queen Critical Grow
And will you be switching to a 600w HPS for flower?
If you check out journals from other growers, a lot of them still use training methods. And honestly, they're not bad things to know and familiarize yourself with. You never know when you might need to use them.
LST is simply using string or something to tie branches down, which forces the plant to grow OUT instead of up. After the plant reaches the size you want, you put it in flower, and slowly remove the ties as the branches stay where you want them.
I would suggest topping instead of a FIM. I tried a FIM, and they can be really difficult. Topping is much much easier, and gives similar results.
You would most likely want to top a Sativa before an Indica. Sativas will grow tall and lanky. Indicas by nature will grow short and bushy. But these traits will vary depending on the strain, and which trait is more dominant.
Height just means you need more light penetration. I got those 3 ounces from 2 plants that were only 14" tall.
I did a FIM in my last grow, and it failed, and I lost a week. Then I redid it, and it only kind of worked. One ended up more like I just topped it, the other I got 3 tops, and it took forever for 2 more tops to grow. After that experience, I'm going to top my next plant, as it's much easier to do.
