It sounds like you have a jute twine which is great. Unless you just crank it down on the stem it is just as safe as anything you could use. Not to mention it follows the organic theme. Normally jute is untreated, and will just decompose in your soil if allowed. It is what they make burlap bags from.
Come here and gimmie' a hug!
Dude grats on the lady parts.
Day 19 is great, that is faster than any female I have had show. So far I think 21 days is my fastest. The males are normally day 18-19.(not saying you have males, just fast ladies)
Oh I wanted to tell you, with the LED being a 250w comparison. It is just the equivalent of a 250w hps. It actually has nothing to do with the stated/actual power draw. Think of it more like a cfl to an incandescent bulb. As far as the power draw is considered, LED drivers are WAY different that hps/mh/cfl ballasts. They normally are a hi voltage, and a low amperage. My cobs run at 27.7v each, but are only drawing 0.35 a, or 350 ma. When you see "compared to xxxx watts" just take it as a suggestion of how much room it will cover.
I'm glad thing are doing good man! I cant wait to see the WC OG mature. I really want to try that strain out. Haha, I'm sure if we all had a 20 acer farm, we would never have a "wanted" strain, but till then, it's on my list. Talk with you later bud, keep up the good work!
