Ive never heard of varying the light cycles throughout flower. As I understand, 12 hours of darkness signals hormones which induce flowering. I remember coming across some survey that proposed the 'best' day/light schedule for maximum yield. I don't remember the result but it was something...

Its a little late to suggest this, but i just thought of it now. Neem oil is suppose to be good preventative treatment for mites. I heard its not good if you already have an infestation, but just thought i'd throw it out there. You take some nice pics. What type of camera/lens do you use...

Sorry about the fish, i hate those brain fart moments. It's too bad, cichlids have an interesting evolutionary past.

how does swim deliver water to his plants? Its an interesting set-up. I think he needs to use better water (distilled or reverse osmosis)and use less nutes than what he had originally calculated. I dont think those clay pellets (hydroton) hold nutrients for very long, but you need enough...

We are just in awe. You might have to wait longer, until the shock wears off a little! They look delicious by the way. Like candy. I like the flood and drain table you got going. It seems like the perfect place in a plants life for that type of nutrient delivery. I bet it sure beats...

I'd lower the strength of the nute solution or just use water. Also lower the amount of water you are using. These are just suggestions. I have read, as I am sure you have, that you want to lower the strength of the solution so that the plants use up their nutes. This is suppose to prevent...

Its unfortunate about the mites. I hope you got them soon and before they caused any real damage. It seems like where you're growing mites are inevitable. I've heard of growers in Amsterdam having trouble since so many people grow and dont take care of their crops. Mites just spread in that...

That stadium puts the Colosseum to shame.

Your cabinet is inspiring. I have a question about the pressure in the watering system. Is there aquarium sealant or some kind of cocking to glue the pipes together? The pump just pushes solution through the emitters without pressure problems or a return line to the reservoir? kiss-ass

All i was trying to say was that if you are trying to cross two types to get the best of both, it doesn't necessarily, and often hardly, works that way. I wasent trying to aggravate you by threatening your knowledge or trying to ruin cruzer's awesome journal. Sorry cruzer, i am just trying to...

If they are F1 hybrids you wont get the best of both by crossing them. because they are selectively bred for specific genes, their offspring might not display the same phenotype as the parents. This is the 'hybrid vigor' that is present in F1 hybrids that is not always seen in the offspring...

Not that anyone is going to see this, but oxygen content does decrease with an increase in temperature. Cold water holds more oxygen. Oxygen dissolves in water and cold water holds oxygen in 'tightly' between H bonds. Warmer water has more energy and can't hydrogen bond effectively enough to...

I have an idea for a cabinet to keep it all stealth with regards to smell. I had an idea about preventing smell while wondering around the duct work section of the hardware store. hopefully some activated carbon used in an aquarium can be made to make a pouch and secure it to the duct booster...

I just read that your hydrofarm drip is: 1 hour on, one hour off while lights are on. Then on for 1 ½ hour twice during the night to keep them moist. is this the same as this drip system?

Thanks man. I like dwc but the reservoir takes a lot of room. i think a drip or ebb n flow is much better suited for a stealth set-up. Smell is going to be a factor for me, tho i love it too! You think that a hepa filter would do the trick for this size room(maybe with some odour removing...

amazing. I had a fight with mites, but fortunately for me i won the fight. What is the height of the flower chamber and the height of the plants at the end? about how far away from the HPS are the plants, do you need to move the light up away from the plants? DO you have a filter for the...

do you have any idea for a filter and fan set up to stop any smell? And have you figured a fan for the cool tube? i'm liking your setup, keep us up dated

this is my answer. dont know if its for dwc or flood and drain (both) Week 1 - PPM: 0 Week 2 - PPM: 0-300 Week 3 - PPM: 3-500 Week 4 - PPM: 5-700 Week 5 - PPM: 7-900 Week 6 - PPM: 9-1000 SWITCH TO 12/12 LIGHTING AND BLOOM NUTES (this is just an example you don't have to switch to 12/12 now)...

nah man, but thanks... I remember i found a list of values that worked great, just cant find it anymore.
