Hydroponics

but i just mean in general, lets say your about 6 weeks in veg and the power gets knocked out, is it a matter of minutes or hours or what? the roots will still be in the water, but no water flow or air pump, how long untill they are fubar?

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.

I'll get you started. just do lost of reading, there is plenty of information online. the charts they give you on the bottles are for full strength nute solution. don't use full strength right off the bat, it will kill the plants. start off at 1/4 strength and work your way up from there. if the plants start to show damage from it being to strong, flush right away then dilute the solution so it's not so strong and try it again. I've used the lucas formula with good results from the start of my first grow. the theory is that floramicro has enough of the same nutes that are in floragrow, so the formula uses a little extra micro and no grow. one less bottle to buy and one less to measure and add to the mix.

I am doing a test right now...

I have 4 clones vegging in a DWC bucket...

So far it has been 3 days without bubbles and they are as healthy as can be...

I have heard hours will kill all every plant, but I am not seeing that at all...

I wonder if they will make it to the 2 week res change....

those are clones though, I wonder about plants.

Right?!?! am I going nucking futs here?

Potroast? anyone?...

i knew what you ment, are the roots just sitting in still water or is there water flow to em?

just sitting in the res... no flow... no bubbles...just a container with Ph'd and nuted water...

First signs of trouble and I'll give them the air... but they are going strong with very white roots...

We'll see how long they go....

hm. interesting. i wonder if the roots can get enough oxygen from the parts that are hanging above the water...

I have a 1000 hps on a table with the potential to put 30 clones @ a time this is my first time growing hydroponically, Was wondering if someone could shed some light on using FOOD GRADE hydrogeyn peroxide for help with O2 or would I be better off using a fish tank pump with holes poked through the hoses to oxygenate the resivoir.
Any help with this matter would truely help I'm actually growing for someone who has a lic to grow the only problem is thy have had tried three times to get growing.... i mean it was bad ive been here three days and they are already twice the size they were when i got here. also is there any charts for using SENSI GROW ? thanks guys

Can burning a propane torch at certain times help with plant growth at all and am trying to save a crop of about 6-8 plants left in a 30 plant table about 5x5 is the tie down method the best one to get the plantsd to cover as much of the table as possible?

I'm starting my first hydro grow, not a big one just two plants, im looking for some nutrients that are efficient and inexpensive. do GH Florabloom & Grow sound like a good simple choice?

you'll need floramicro to go along with them, that's not one you can leave out. search the forum for the lucas formula. you can grow without floragrow. I have all 3 bottles, but I've used the lucas formula for my whole first grow with good results.

So the Bloom, grow, and Micro?

Lucas formula says to not even use grow, cos micro is enough N.

So i should buyy Floramicro and bloom , yea?

Well....Agricultural grade h2o2 is 50%, I think food grade is 35%. The main reason for using h2os if to control pathogens in your res. It does add a liitle oxgen in the process. If you are using organic nutes it will kill them too. Air pumps and air stones are not expensive, I use a double air pump and 2 air stones in my reses and skip the h2o2. Water temperature has more of an effect on the amount of dissolved oxygen that stays in the water than any introduction of h2o2 will have. 65 degree water will hold tww=ice as much do as 70 degree water will.
Sorry, not familiar with Sensi Grow. VV

Hey there Potroast, how is everything going?
Everything here has been rocking pretty good in the AF. I am noticing an arrising problem on the girls I have in week 6 of 12/12. Maybe you or somebody can help out? Here's a pic......


I am using Canna Aqua by the book w/ cannazime, rhizotonic, boost, and I only used the pk13/14 in week 4 when the buds first started......but I am where I think I should be with the nutes right now?---> and working my way down from 900ppm.
I had a good case of nute burn a couple of weeks ago, flushed and seemed to come back fine.
Now these upper leafs are looking to be Molybdenum def----and it's odd because it's just these plants in the middle section of the AF20 and when this happened one year outside the leafs curled up......
Ph has been very stable 5.7-5.8........ Should I increase it to 5.9-6.0 to better absorb Mo?
Any ideas??
Everything else in room is stable:
temps lights on are 77-80, light off 67-70
RH is pretty consistant around 50%
The AF has 2 600's a good 18+" above plants
Good air exchange: 400+-c.f. w/240cfm running about 50%

System is AF20 aero/nft
res temp a bit high at 70-72
ppm is currently just below 900ppm

I appreciate any help or ideas......I think these will finish just fine but dont want it next time around.

Thanks very much!!

Alright... I'm new to this site so bear with me.. I've got twenty eight urkels under six 600w hps. Doing an ebb and flow using rockwool(4 inch blocks cut into 6 inch blocks). Good ventilation... Two 8 inch cans 1 in/1 out with filters... Using Cutting Edge nutes at 3/4 strength. Flooding the tables once a day(about 2 to 3 inches up the side of the block) right when the lights turn on. Everthing looked fine until about a week into my 12/12 light cycle. I thought it looked like I was burning them with the nutes a little(yellow tips on the new growth), so I flushed with 1/4 strength nutes for a week before returning to the regular flowering nutrient regimen. They have progressively gotten worse since. ALL the big fan leaves are dying super fast... Turning yellow and purple with brown spots. I'm now three full weeks into flower and I need to know WTF I can do to fix this fast. I'll try and put some pics up... HEEEEEELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Mendo, looks similar to my problem in previous post.........yours a bit more purple...
Did you give any veg nute after going 12/12? That's the only thing I did different with this grow: I just went straight bloom nute from day 1, 12/12..........well, other than the FACT this is my first hydro grow haha
I 've been reading up on N def in early fowering and it can end up being like these are. And mine are more yellow than yours, but other than that they have the red veins and purpleish tints in the leafs.........
