I have a BestVA 1000w LED light ($139). It's got the latest 10w chips and draws 185w. Even tho my BestVA light is rather small (12"x 8")...why are some LED lights that cost $900+ (8 times the cost of my BestVA) not 8 times larger?

I've raised up the light to about 20" from about 16" inches. I sorta doubt my problem is too much light intensity, but for experiments sake, I raised it up to 20" from the top of the plant. There was NO sign of leaf burn at 16", but then again I'm willing to try 20" just in case my slow...

I just want to add that my delivery water company, Pure Flo, puts stuff back into their water. They add Calcium Chloride, Magnesium Sulfate, and Sodium Bicarbonate (to raise the ph, no doubt). I'm not sure what quantities of these chemicals they add. They refuse to list details about the exact...

BestVA 1000w. I agree the growth is slow. I may not have been feeding it high enough doses of nutes. I've always held back after reading how some cut their nute doses in half (might have been a mistake). I may have been doing that too long. I'm also raising the light up another 10". Even tho...

First of all, I'm not shelling out big cash for a CO2 tank and regulator. If you have the bag hanging over your one plant, doesn't that impede the plants ability to exhale oxygen during it's sleep period? So, I nixed having it inside the tent, but instead have it dangling outside at the bottom...

Just buy a product called Cal-Mag or Cali-Magic (Google it). Follow the directions on the bottle.

The consensus seems to be that darker than normal leaves are caused by a nitrogen excess.

Alaska fish oil quart (5-1-1) was only $5.99 at Home Depot, so I bought it. I'm slowly going with other makers of liquid fertilizers that maybe offer more micro nutrients. 5-1-1 isn't bad for veg growth, I suppose.

Noted. That's why I thought I was getting a nutrient lock out, due to the nitrogen overload, even with FF's Happy Frog mild soil. As you say...if I only added 1/2 the recommended dose of Alaskan 5-1-1 (every other feeding)...that should not be too much nitrogen. I feel as if I should show...

I've just started adding Cal-Mag due to using RO water (4 week old plant -oops!) and for leaves with white tips (I read Mag deficiency caused that) . I've not read of dark leaves due to a mag deficiency but the Cal-Mag should improve the color of the leaves if that's the case. The dark leaves...

I guess all I was replying about was that micro nutrients seem to play an important role, and I shared mine about Cal-Mag, since you mentioned Cal-Mag in your original post.

Some say it's lacking in phosphorous. You might want to use a product low (none) in Nitrogen such as FF's Big Bloom to prevent nitrogen overload but which adds P and K nutes. I was using Alaska 5-1-1 fish oil and my plants were getting too much nitrogen (dark leaves) and not enough P and K...

I too just bought some Cali-Magic (Techniflora) because I was using RO water. The leaf tips were turning white. After adding the Cal-Mag, the new leaves aren't showing much white tips anymore. BTW, if you're thinking of buying Bontonicare's Cal-Mag, there have been reports of the solution being...

I bought one Pineapple Express clone. I used a mixture of Kellog's Patio Plus and Fox Farms Happy Frog and some perlite mixed in. It's growing pretty well under 1000w LED. One thing I'll remember for future grows is...I started adding Alaska Fish oil 5-1-1 after the first 3 weeks at HALF...

Ya, except all the Google searches for it were all from the UK. It also needs to be wired in.

For 4" and 6" Vivosun type plastic fan housings, I took a 12x12x13" cardboard box (for 4" fan) and cut two U shaped cutouts so the box would fit over the unit's 2 ducting connector openings. I then went to a carpet store and they had a stack of carpet samples that are discontinued. I got 5 of...
