There are no ducts in house. The heat is Radiant heat thats plastered in the ceiling. Crazy I know but it works well.

So would I just put a "Y" fitting on the duct of the cool tubes and dump the heated air from the bulbs into the grow room instead of outside grow room? And the exhaust fan wired to a thermostat will control the overall temp of grow room? Thanks for all the help guys, I'm starting to see it now!!

Well here's the deal guys. I'm setting up a grow room based on al b. fucts how to grow 1.5lb every 2 weeks. The room is going to be set up in a 900sq ft unfinished basement. There is no heat or a/c in there though. And it's winter here now and the outside temps are 20-30F, while the basement is...

Yeah the description on the box said it raises the temp 10-15 degrees F above room temp!!

Hey Al I talked to you a couple days ago about some of my clones drooping and wilting. I think I may have found the problem. I think I read your heat mat is fixed at 30 degrees C. I just put the sensor of my thermometer in between the heat mat and tray and it's showing 43 degrees C. Do you think...

Yep I used denatured alcohol to dip the scalpel in, and added 1.7 ml/L to 35% h202.

I forgot to attach the pics, here they are.

Yeah they had about 7 hours dark as I just turned the light on when I got up out of bed this morning. Do you think I should shut the light off. I did leave the front off of the clone box and my 400 watt mh was on about 8 ft away, would this have affected it at all maybe?

Good morning Al. I took my first batch of clones last night about 7 hours ago and come to check on them this morning and noticed about half of them drooping ptetty bad. Below are some pics I included to help diagnose the problem. I'm pretty sure it's not over watering as I weighed each cube to...

Hey Al I had one more question. I'm taking my first clones off my mums to determine their sex. When they are in the clonebox and eventually set root, can I just switch the flouros to 12/12 and sex them right in the clonebox? Also should I hand water them flowering nutes at 1400ppm until they...

Hey Al I thought I read some where you keep your freshly cut clones in the dark for the first six hours or something like that. Could you tell me what your lighting schedule is for your clones? I just finished building my clone box and am ready to take my first batch of clones!!!

What's going on Al, I had a quick couple of questions for you. When I'm taking the clones once they are showing roots through their rockwool cubes and transplanting to their pots do you have to hand water for a couple of days until the roots find their way down into my nutrient soaked pellets...

Thanks again AL for the quick reply. I must say you have to be the biggest asset for this online community. Much respect for you bro.

Yeah the instructions suggest to keep a little of the calibration solution in the protective cap for storage. So you're saying to just cut a little piece of sponge and place in the cap and keep it moist with water? Calibrate before every use!! I didn't know that, glad I asked now, thought once...

Hey Al, I had a quick question for ya. I purchased this meter about 10 days ago and calibrated it when I got it home. I just checked it tonight and the calibraion was like .7 off I think when dipped into 7.0 calibration solution. Is this normal? How often should you calibrate your meters? It has...

Hey Al, I'm still working on raising my mums. I'm getting ready to take clones to determine which are female. My question is it ok to to put them under flouresccent lighting @ 12/12 to get them to show sex?

Hey Al could you tell me where I should cut this to top my plant? And by doing this it will make my plant what? I know this is a lame question I just want to make sure I don't screw my plants up. Thanks again!!

Good morning Al, I was looking over the homemade batwing reflector in your gallery and was wondering what size (thickness, width, length) sheet of aluminum you would suggest to make one? Also, how effective do you think this DIY version would be compared to the $200 original one. I'm going to...

Hey Al just thought I'd let you know I drove my ass an hour and a half back to my hydro shop and got my ph meter today, got home and tested resivor and it was at 5.6. Corrected to 5.8 and we'll see how it goes. Hopefully see some changes in the next week or so. Thanks again for your help!!:mrgreen:

Hey Al I got another one for ya. How do I determine between nute burn and a deficiancy? I first thought the yellowing dying leaves at the bottom were from nute burn. So I backed off the PPM for a week no change so then I figured it was a deficiancy so I just up'd the PPM to 1100 just now. I...
