chains and S-hooks work pretty well, especially if you aren't moving the lights a lot. I tend to move my lights a bit, so I ran some eye bolts into the ceiling studs and hung it all on pulleys.

why would you ask that on a site dedicated to growing, ask a doctor :)

it's not really exact at all... For instance, it would indicate that one plant under 400w of light would yield 400g @ 1g/w. If you had 10 plants under 400w, you'd expect around 400g, or 40g per plant. Again, it's completely independent. Now in the real world it doesn't work out this...

not sure where your info is from, but if they are indeed fungus gnats, they won't harm most plants. The gnats themselves live for 24-48 hours, and are simply a nuisance. They will get stuck to your buds mostly, so if the idea of smoking a desiccated insect with virtually no mass isn't...

it's incredibly strain dependent, so there is no *normally*. The best advice here is to take pictures, if after 2 weeks you see no difference, you have a problem. It is not abnormal for strains to slow down dramatically for periods, and also, as mentioned, there can be growth behind the scenes...

I go by weight as well. If it's not possible to lift them at any point, you can also get meters that stick in the soil and measure moisture levels.

Can't speak to the strain, but .09 per watt is a weight per power ratio (and not a very good one, I imagine they mean .9g/w). What they are saying is completely independent of plant numbers, size, or any other environmental factor other than light received.

for sure the easiest, and yeah, for 2 hours, and the risk factor, I would just not worry about it. I've also had all sorts of things happen to grows unexpectedly. light goes out and they get an extra day of dark, visiting parents snoop around closets and open a door for 4-5 seconds when it's...

Sounds like you are a bit away from leaving, so I'd postpone any decision till as late as you possibly can. You might get an indication from the bud itself. If it were me, I'd look at what I thought the window of ripeness would be, and just before you leave decide if you think it'll still be...

let the lights go off for 2 hours. The flower period is determined not by the amount of light, but by the amount of dark. You aren't decreasing the dark period, so really it will make negligible difference to the plants (a few less hours of photosynthesis). Figure you just had a huge cloud...

it will help reduce the zone of increasing heat surrounding the bulb, it will also slightly increase the ambient temp in the whole area (or at least spread it out a lot more).

I've been using FF nutes for a while now and have been quite happy with them.

that doesn't look bad at all, I've done much worse myself :) You damaged the tips of the shoots, but not badly at all. The growth shoot looks undamaged. Good chance it'll continue growing fairly quickly. Keep in mind though, any burning means less sugar production, and that in itself will...

put them in soil, keep moist for a few days, I've been surprised in the past at germs that I thought were gonners popping out up to a week after I tried them in soil anyway. The germ rate is bad though, so you might get nothing. On the drying out, you either have it too hot (try towels between...

not bad looking, but I would suggest moving lights much much closer to plants. I have a 4' 8-tube and keep it within 2 inches of the tops with just a $12 oscillating fan blowing on the bulbs. Without the fan I could get 3-4 inches. The response you see from t5's being that close is...

yep. I get them shipped to a friend who is clean nosed and couldn't be targeted for anything more serious. He doesn't know what he is getting, other than it's mildly illegal and could result in a small fine, which I would pay. I assume he thinks they are tobacco seeds (something I have grown...

Normal for some leaves to die when cloning, however for them to do it in 3 days makes me think your humidity dome is either not there, or not effective. Could also be other things, lack of oxygen, to much heat, etc. But as mothers finest pointed out, to a point this is normal, they will start...

I am having trouble following your post... But I've used techniflora mag-i-cal. Was always quite pleased to it, only reason I stopped using it was I went to a single n-p-k mix with mag/fe/ca. I have never liked all these complicated schedules and multi-part mixes. Other than a change from...

yeah, I'd have to disagree as well. Though different nutes are for different applications, you certainly can get nutes with the 13-14 necessary micro and macro nutes needed for herb. In non-inert substrates it's not even necessary since there are a chunk of them naturally in soils. Also...

look for states with new laws. The longer a state has had medical the more saturated the industry tends to be. Also it's not uncommon for states to start with a broad statute leaving room for a lot of people to get into the industry, but later restrict it further (like colorado), and in many...
