yes, I thought this was the issue last time, so i changed drippers to 4 min off 1 minute on. The 6 plants in that system are still dying at fast rate the SAME way. I will move the timer to my new system (one pictured in this thread) and see if it changes anything.

I think it has to do with temperatures somehow. I have never had such widespread crop failure since trying to grow in the winter. (3 different types of hydro systems and similar root death eeach time). Normally in the summer my room temps were about 10 degrees higher...and NEVER had problems like this....could still be something else however.

okay, big news today. I took out my last healthy clone from its tray. My intention was to put it in the same drip system and see if i could eliminate ph and overwatering from the equation.

As soon as I lifted the clone out of the tray I could tell it already had the same problem as my drip roots. The tips were kinda of burnt off in exactly the same way.

Since no ph down or nutrients are used in cloning i have determined that temperature must be the problem...

I thought u guys said my temps were cool beans.

room temp-65-72
water temp-69-73...i don't let it get to 75 ever. ???????????????????????

I use distilled water with a pH of 5.5 and some clonex clone nute solution and soak the rock wool cubes in it over night. When i take my cutting i use the clonex gel and put them in the presoaked cubes, that way they have some available nutes to feed on when they start to root. They need a minimum amount of nitrogen and increased levels of phosphorus to promote good root growth when rooting clones. I do not put any water or solution in the bottom of the tray. Instead i have my solution in a large picture and i dip the edge of the rock wool cubes in the picture when i feed them. That way the cubes soak up the right amount of the solution and they do not get over watered and they are not sitting in it which could cause the roots to start to rot. Your clones roots can be damaged if your medium goes over 85 F. A warmer substrate increases root growth and lower air temps slows transpiration. For the best results keep your growing medium between 75-80 F and keep the air temp 5-10 degrees cooler than the growing medium. A warmer growing medium coupled with a cooler ambient temps slows diseases and conserves moisture. Check out AL.B clone journal it my help A batch of clones in rockwool

lol, yes i have read pretty much everything that al.b fuct has posted...ever. I appreciate the cloning tips, but normally I have about a 90% success rate of cloning. The clones I had were all great with no sign of root damage until the same 1-2 day period when the drip system had the root damage occur in the same fashion. Since the two systems are in the same 4 foot radius I am guessing the problem has to do with the not so perfect temperature they experience. It is possible the room reached a lower than 60 degree mark one night last week. I am currently testing this as my last variable by placing 1 more clone into a room that is consistently 75 degrees...*crosses fingers*

Like DND said, light. If your roots are slimy it's probably algae from the light getting thur the rubbermaid. Like everyone else said, paint it black.

k, not to be an ass, but I noticed what everyone else said.

1) The clone had only been in the extremely clean and mylar covered drip system for 3 days before the roots got the damage(pictured). It is virtually impossible for that tub to get algae or "slime" in that short amount of time.

2) as i stated before I have had this problem in 3 completely DIFFERENT systems. This means GH aeroponic system, drip system another drip system and a clone tray. This is why I am guessing that it is a temperature related problem. (root problem occurs in any system i use)

3)I know what algae and "slime" looks like...this time around I have neither of these issues.

At this point it really MUST be temperature or over watering. I am testing the over watering variable right now.

thanks for everyones help really...ill report back soon.

I'm sorry I thought I read somewhere that you said the roots were slimy. But it is totally possible for algae to grow in 3 days, but since you ruled that out whatevs. good luck, hope they pull through

i dont know if you said it or not but do you use tap water? i use a clorine remover and let my water sit out for 24 hours because clorine will burn your roots like that. if i dont use the clorine remover i let the water sit out for 3 or 4 days before giving it to the plants just a thought hope it helps

Intersting bwinn...I have been considering this as a variable lately as well. I have always used my well water, which has a default of 10 ppm. The reason I have not considered the water a problem until now is because it (the water) has worked for me very well in the past...several times. So you just put a bucket aside with proper amount of h2o and let chlorine dissipate? Does chlorine remover have any adverse effects on plants or add ppm etc? Not sure if it is a factor for me, but I would love to eliminate it as one.

Good news is the roots appear to be partially recovering themselves after a few minor changes. The problem is that the new roots appear to be be burning the root tips just like the previous pics. (roots r from same plant). Now I believe that overwatering has become an issue beacuse my damn timer broke... I have one of those expensive $100 CAP 4-1 timers. Neways sometimes it decides to go thru its on cycle 2-6 times instead of once...ugg..hopefully a series of miracles will occur that keep the timer on a descent schedule. Ordering a new one this week.

roots are still growing with a vengeance and i am loving it. This is the first successful set of roots I have maintained in over 2 months. You can even see the other ones in the background FINALLY starting to poke out of their nets.

Temperature fluctuations and over watering were my issues as far as I can tell.

Basically once my room reaches over 72 degrees my water temps try to tag along. Since I do not own a chiller I just vent my room out until the water temp goes down as well.

This method is not good as u usually end up using ice cubes (uknown h2o content as well as ppm) and requires a constant watch. Other than that my timer broke and there is really nothing I can do about that. CAP is replacing the timer this week sometime.

QUESTION

1) I am new to drip systems and was wondering when would be a good time to let the roots hit the water. They are reaching out like social services, but I think they like the space...any thoughts?
