heys guys, I got some of your advice from my post earlier about organic vs. chemical fertilizers and I understand now. But what I was wondering is what all do i need to know and have to produce F1 grade bud that I would enjoy. Here is a list of things that I have to start out with. a 4 by 6 room thats painted white,a vented growzilla reflector that houses two bulbs, 400 watt hortilux hps, 400 watt MH, squirel blower with 240 cfm, the room stays at about 80 degrees with alittle help from my window air conditioning unit. I've got an excellant strain called Cyrstal. i have two of them in flowering for about 3 weeks but after reading about mircale KILL i'm interrested in changing. So any other items that i may need would be a great help in acheiving this goal. My first crop ended up with scraggly buds but i'm asumming it's from the 400 watt hps that i used from start to finish.

To effectively light a 4' x 6' room (24 sq/ft.) you need 1,200 watts HPS.
-HPS is an excellent light start to finish.
-You need to monitor/adjust pH.
-You need to monitor/adjust ppm.
-Ventilation is the factor most often overlooked in indoor gardens. Marijuana needs LOTS of fresh air, and I DON'T mean leaving the closet door open with a fan stuck in there.

i'm growing in soil so do still need to watch the ppm and ph balance in the soil. some one said that distilled water is the only way to go my tap water is about 6.5-7ph.

4' x 4' - 16 sq/ft. Using the rule of thumb of 50 watts HPS per sq/ft, you need 800 watts to effectively light that space.
You need to monitor the ppm & pH no matter what the medium.
Shop around. I've seen combo ppm/pH meters for as low as $35.00.
General Hydroponics 3-part system is hard to beat, but if you're growing in soil I'd go with an organic nutrient, like Pure Blend Pro.

Bat guano comes in varing amt.'s of nitrogen and phosphorus, make sure you get the kind you need.
Guano is a great addition, but it contains no micro-nutruients or K (potash or potassium), both of which you need.

You can get Pure Blend Pro at grow shops.

I have been growing since '67.
