LST is great for: 1. Make an outdoor crop look like something other than marijuana. 2. Keeping height down in a cabinet. 3. Evening out the tops of your crop to maximize light distribution.

This is a very interesting study. According to some of the data from the Drummer study in Australia, THC levels of over 5 ng/mL in the blood corresponds to an impairment greater than of that to someone at the average legal limit for alcohol. The general consensus is that anyone who argues that...

Just doing one more check to see if anyone else has got this going on. I figure there's no need to panic, but if I'm somehow compromising my nutes, that'd be good to know.

T5's are a step down from HPS, but it's a slight step. If you keep em close, they're very effective.

So they'll take enough moisture through the stem to survive without a dome? Neat, I'm making one asap.

I've had 6" clones hit 3' by the time they're done. Maybe it's just the strain I've got, but it grows through flower like a madman.

Where are you going to get the electricity to recharge the batteries if you were to do this? Not to mention that power is lost in the charging and also the inversion from 12V DC power to 120V AC. Batteries are very expensive, and so are inverters. Just keep your operation small. The electric...

Pruning can be legitimate and in some cases increase yields. Topping a plant makes it branch out. Removing sick or dying leaves helps the plant by allowing it to use the energy it would trying to repair a dying leaf, and directing it into new growth. Thinning top leaves during veg will make...

If you take a clone and drop it straight into 12/12 flowering, it'll usually get to be at least 3' tall by the end, and maybe more depending on the strain and how much light you use.

Scrog doesn't necessarily require more veg time. I run clones straight to 12/12 upon transplant and use homemade wire clips to form a LST scrog that sits about 4" above the base of the plants. I run about 2 plants / sq ft. It keeps the height under control and allows me to maximize my space...

Judging from the state of those leaves, there's definitely been some stress in that grow. Either way, go back over your grow and ask yourself what you could do better. Also, start out with a better strain if you can. 95% of bagseed is junk sativa that somebody picked from an outdoor plant-it...

Scrog is full of win.

Here's how I would look at it: Cops won't buy the "I didn't know he was growing" argument unless it's an extremely small grow in his own space. If it is an extremely small grow, it could be a misdemeanor and you wouldn't even have to sweat it all that much. Now if it were a big grow, then it...

Much cheaper supplemental lighting would be some CFLs. LEDs cost some serious $$$

I'm curious as well. I use floranectar and I'm not sure if I should add that to my res for the last week before harvest.

You could make a frame out of PVC elbows and pipes that sits over your pots on the ground.

In a cabinet 4' tall, you're going to have to scrog to keep the height down. Clones dropped straight into flower easily reach 3' tall (not including pots / root chambers). I would recommend two smaller lights (200W would be fine) in such a short cabinet. It'll distribute the light more evenly...

Once seedlings start getting full fans of leaves like that it's time for nutes. The burnt leaf tips is an early sign of Nitrogen deficiency. Give them an all purpose grow fertilizer and they'll bounce back in a couple of days.

Go to Radio Shack and ask for a pocket magnifier. They're like $15 and you'll be able to know for sure if it's mites or not.

105? Oh yeah, that's going to cause some heat stress. I've had heat stress look exactly like that: wrinkled leaves with colorless patches on the edges. 85 should be your max temp.
