Hydroponics

Yes, a Cool Tube or any air-cooled hood for your lamp, with the hot air exhausted from your closet. Air conditioning should be a last resort, after all other ventilation is taken care of. The larger your plants get, the more cool fresh air they will need. Yes, ideal air temps in the 70s.

hey potroast (or anybody), what about low temps. my room gets down to 55f-65f at lights off. what you think time for some heat, or is it ok?

Average 60, sounds like fall temperatures too me, nice and warm during the day, lots of sun, slowly cooling down at night. Below 50? its time to start considering some heat. Until you get to freezing, lower than 50 will impeded growth, not kill them. VV
 
I forgot to soak the rockwool cubes before I put my seeds in them. They're growing but just not very fast. Will this be an issue down the road or will they pick up the pace once the roots hit the water properly?

Hey Talon, sure. Read the start of this thread, pot roast cover all of the different Hydro system and the mediums or mediumles grows. I think its all in the first fourteen or so pages.

Well.......hmmm...... so what have you done since then? I am suprised that they are alive, I am going to guess that you have been using ph'd water on them and possible that has corrected the problem. Not sure of any of the details of your system, I would assume your talking DWC or Aero. If your roots make it to the water and you are making sure the water doesn't hit the cube, they will probably be fine. VV:shock:
 
Thanks VV,
They are still alive and thriving. I took a look yesterday and the roots are starting to come out of the pot, which is a good sign. I'm running an aeroponics system. I haven't messed with the ph yet. It's steady between 6%. Here are some pics at one week. I also have three in soil. This won't be an issue will it?

Those plants look healthy, soil ph should be around 6.8 if I remember right, your aero system would be run at 5.8.
You may see above ground growth slow for a while ubtil your plants fill the pot with roots, those look like about 3 gallon pots. After that the will take off and catch up so its not a big problem, an extra week should do it. Your planning on using these as the mothers? VV
 
is it better for the plants to pluck fan leafs? im in my forth week of flower and it dnt look like its growin quick enough. its a pretty site but it just seems a lil off.

Every 4 hours is good, but the 15 minutes is not needed. It's best to flood to max level and drain. With a loose particle medium like growrocks you just need to wet and re-aerate.

Thanks!

Will it hurt anything to flood for 15 min.? I do have an airstone in the res...

I got to get a better timer.. I am using the cheapo plastic ones with the little green and red ticks....

Thanks Again!! I appreciate all your help!:clap:

Here is a quote from another post...

My little lady is starting to make some bud. Does anyone ever cut off the lower leaves? Will that hurt anything? My reason for asking... I was just curious if the lower parts of my plant would benifit with more light if I trimmed her down.

Leaves turn light into food... take away the leaves.. take away the food...

Add more light.... side lights... whatever you can do to avoid cutting leaves...

but if you feel you must..

this is a matter of opinion and technic. more light is always good, so it does hold true, but many books say to trim the lower branches to allow better air circulation and focus the plant more on the parts that will produce bud. in either case, don't trim to much.
 
HELP! my plants are dying off fast. I tink I have a major problem with algae. And now that i have covered the tops of the cubes it seems that mold or mildew is present. I am doing a ebb and flow using dutch trays and a 1,000 watt light. Slow growth nutes are at 850 ph is 5.8. I was over watering corrected that and now I think this algae is killing them off! what can I do to get rid of the algae?

Trimming/pruning certainly has it's place... but you gotta be careful...:-P
 
i have a question about nutrient solutions... i have the GH 3 part series (grow, micro, and bloom), what do the numbers on the bottle mean? (Example: florabloom is 0 - 5 - 4 ) Also, do i use all three of them at once, or only mix two, or should i just use one at a time. please help me. i'm new to this. i literally just started growing about 2 weeks ago. Never done it before. i got me some white widow seeds and i'd hate to f*ck it all up. oh yeah and can somebody explain the lucas method (i think that's what it's called). your help will be greatly appreciated.... thanks people.
 
QUESTION.

how do you guys add nutes to your dwc

i was thinking changing the pure water out with pre-mixed nute solution but i read earlier in this thread that you could go a hole grow without changing the water

wouldn't it be bad just to dump it into the res? I was thinking it would burn the plants before it mixes

I'm gona use cn17 grow/bloom (liquid)

thanks in advance,


and to attempt a decent answer on the previous question, its the nitrogen / phosphorus/ ¿ potassium ? ratio of the nutes. it goes n/p/k , you want a high n for veg and high p for flowering

there should be a chart on the bottle telling you how to use them, start with all grow, transition all to bloom
 
lets say you lose power during a storm or something, how long can the plants go in a hydro set up before serious damage is done?
 
it depends on the setup i have a dwc and i got a 4 hour air pump power supply from the pet shop so if power failur happens im stilll safe
