Thanks tf, that was me who asked. Looks like a pretty big root system thx

great journal. keep it up

Awesome info and ideas

THX for the info but I am still a little confused about the fence posts you speak of is this just the dug out for the net pots. do you have a layer of rocks all across the bottom? 2 and a half lbs on that grow! awsome almost 1 g per watt

. Any way you go in to detal about the medium u use under the plastic for support. Thx

What's an elbow lb ?

Nicely done TF. Thanks for keeping us posted. Did you veg at all? What is the highest ppm you run in flower? Thx

Called the manufacturer of my tds pen meter (nutradip) and asked what conversion scale it was on. He said 700 (or 442) scale but also told me doesn't matter because meters using 500 (or NaCi)scale would read exact same ppm in my res. He says that they have different calibration solution for...

One word: abamectrin (sometimes spelled avamectrin). There is no substitute. Kills spider mites every single time. However, if you ever get a spider mite infestation, the grow op has to be cleaned out totally and vacuumed THOROUGHLY or they'll be back. They're clever little bastards and will...

Thanks for all the help with the electrical ABF May seem like a dumb question but was wondering were I should place my thermometer in the grow room. Should the temp be at 25 degress directly under the air cooled lamps? If I move it outside the tables I loose 5 degrees. Were should the temp...

Nicely done keep us updated.

Looks great man! How much you think yield will be?

Thanks Al, Would that be called a double pole thermostat? What are you using for your intake fans? Do you run two thermo switches, Or does both your intake and exaust fans run on constant Motor speed controller when temps are down?

If you have 'power looping back causing the intake to run continuously' you've wired it wrong. Follow the diagram I drew for you. No diodes are necessary in this situation and in fact with AC, would create problems. Check your wiring & try again...

I live in central Canada and I am not shure of the best way to controll indoor temps when pulling cold intake air through the window. I always thought that exchanging air inside a tent with frsh outdoor air every hour was very important for indoor growing but this would make my room drop to...

its thanks, I am quite aware of Al's thoughts on h202 and why it's used. I just like hearing what others grower find helpful in there res.

you have a chiller for the res? what temp do you keep it at?

Thanks for the info hb . I can't seem to find dyna gro protekt local. Maybe I'll try elsewhere. I was going to run some h202 In my res because I know al b fuct has great success with it at 1 ml per liter but that is 50% grade. In Canada 29% is the strongest they can sell so I would have to add...

Thanks for the link I would love to find some of that big chunky stuff. Looks like it would provide alot more air and stay in the pots well . Are you using any h202 ? I know al uses 1 ml per liter of 50% grade. But I can only get 29% so I would have to use 1.7 ml per liter Which would be over...
