Gypsy, you are a wealth of information...I'm going to stop spreading all those nasty rumors about you ;)

Interesting...Is that a 1" cube? How do you ensure the roots don't dry out b4 they reach the solution? or do the pellets wick the moisture up?

Do you use the formula GH suggests, or do you adjust it for growing mj?

I was concerned that 3x/day might be too much, glad I asked. I've also read that rockwool is not ph neutral. Is that true, and if so, what should I do about it?

I've got my equipment, and am building my room next weekend. I"m doing two 4x4 flood trays under three 600w Hortilux Super HPS inside Xtrasun air cooled reflectors. I'm planning to root clones in 1" rockwool, transplanted 8" apart in 4" rockwool cubes in Hydroton. I'm going to flood 3 times a...

I'm about to build a 4x8 ebb and flow for a SCROG myself...got all the equipment last weekend, lights, 4x4 flood trays, fan, filter, etc... I was going to go to Home Depot this weekend and get the materials to build it, but it turns out I'm having company this weekend, so I have to wait till...

ya a filter for the odor is an absolute must...your security depends on it....if you get busted, they don't let you bring your buds to jail with you

Can anybody help me? Puhleeeze?

I'm about to start my first grow on two 4x4 flood tables under three 600w HPS. My room is 10x12x8 and after visiting the Can website found I would need a 6" HO fan paired with a Can 66 filter. The hydro shop didn't have a 6" fan so he gave me a 8" HO and Can 75 for the same price. IT IS LOUD AS...

Attached is a closeup of one of the trays. Should I put the clay pellets directly into the tray, or should I put down a coco mat first to prevent the pellets from fouling the channels and impeding drainage?

I keep reading about people using pots or grow bags in a SOG. Do I need them? I'm using two 4x4 flood tables under three 600w HPS. I am going to root my clones in 1" rockwool then transplant to 4" rockwool in clay pellets directly in the tables. Is that okay. I've spent all my money, and can't...

I'm not an HVAC technician, but I know that the heat energy you're drawing out of the room has to go somewhere. Where it goes is into the coolant, which is run through a radiator to dissipate the heat outside. In a window unit, that radiator is in the back of the unit, which must be outside, or...

Actually, there is another way, but I'm not sure and would like Brick and VV to comment b4 u try it. The circuit going to the garage, if its 1-pole, should have a hot, neutral, and ground. You could go back to the main panel, take the neutral off and put it and the hot on a 2-pole breaker. Then...

But, dude, check and see if the panel is one leg or two. If its 2 then you have what you need right there in the garage. And single pole panels are not commonplace. Do you have a voltmeter? Open the panel and put one probe on each breaker, if you read 240v your all set. Again, this is assuming a...

A voltage transformer raises or lowers voltage. Your thermostat uses 18 or 24 VAC, so 120v is fed into a low voltage transformer, and 18v comes out. Utilities use high voltage transformer. Have you ever wondered how the utility can power you entire neighborhood off those skinny lines on the...

the 240v won't look the same as the 120v, it has an extra prong, cause its two hots, neutral and a ground
