I wouldn't, all chemical fertilizers use salt as the catalyst so you'd essentially be putting salt on your leaves. I won't say that this is the first time I've heard of such a thing but plants do their nutrient uptake through the roots.

With only two plants in a very small area you could get away with as small as a 100 watt MH/HPS. I use one in my starter closet (18" x 24") with great results. I've even taken one plant to maturity in there and got a 5 oz yield off of it. Mind you, it was probably a heavily Sativa strain but the...

Nah, but sounds like fun. I just use GH nutes but I do use nitric acid to lower pH. I've never actually had to raise pH. I use distilled water exclusively. They throw a bunch of lime in our tap water and it runs 250-300 ppm and 9.55 pH. No, of course, nature is highly adaptable, things that...

I had to take a boat load of chemistry in college while I was working in pool/spa maintenence at the same time, I understand pH. :)

pH is critical in cannabis cultivation, in fact, I tell people it's probably the single most important thing. Below a certain pH and certain nutrients are locked out. Above a certain pH and certain other nutrients are locked out.

In their new homes:

Oh yeah, they were rootbound:

Well, my medium is drying up daily now, and I have 5" - 6" plants in 8 oz cups.

Thanks, that's what I was thinking, the less shock the better.

So I started my babies in 8 oz cups this time and they've outgrown them, it's time to transplant. Previously, I've stared them in 16 oz cups and then transplanted to 1.5 gallon pots. Should I transplant up to the 16 oz cups now or go straight to the 1.5 gallon pots? Thanks! Aussie

That's enough for about two square feet, whereas your 4' x 4' grow area is sixteen square feet.

That only comes out to a little more than 1000 lumens/square foot for a 4' x 4' area, not nearly enough.

Again, don't go by how many plants you want to grow, measure your grow area, provide 5000-10000 lumens per square foot, then decide how many plants you can grow in that area. EVERY bulb out there is rated for light output (lumens), so you shouldn't have trouble finding this number.

I use a 100W MH in a 18" x 24" closet as my starter and even with a couple of single bar 3' T12s it's barely enough. What you're shooting for is 5000-10000 lumens per square foot. Don't gauge it by watts or even number of plants, you want to figure it by lumens per sqaure foot and then decide...

Well, I can't speak to the seeds you're using but I can say your light seems a little on the low end for your area and the number of plants you want to grow. Also, the more area you give the roots the better. If you're only going to use two litre pots and a 150w light then I wouldn't recommend...

You get what you pay for. I bought a $20 meter and spent far more time calibrating it than using it. I'm pretty sure it was still inaccurate.

Ask 1000 different people and you're going to get 1000 different answers. I'm currently doing my first organic grow in a mix of 1/3 ProMix, 1/3 perlite, and 1/3 worm castings. I haven't given them any chemical nutes and they're doing great. When I was using hydro nutes I was using 100% perlite...

The peak for photosynthesis in veg is at 5500°K and for flower at 2100°K. The curve drops off sharply on either side of these numbers. The color of the light is far less important than the quantity of light and it's difficult to give your plants too much light as long as the temperature is under...

Actually, IR sensors are entirely passive, they can see heat emissions but emit no energy themselves. This is what makes fighter jets equipped with IRST, Infrared Search and Track, so dangerous. They can track and target another aircraft while emitting no signal themselves. They then employ IR...

Sorry, still not giving your malware to anyone here. In the words of Pink Floyd, "no-oh, do it again....".
