Ok having read up i'm starting my first grow, 12 Ice planets in a NFT hydroponics growtent.

First up, here's the setup

Here's a pic of the seedlings just popping out of the small rockwool blocks...

Here's a pic of the lot under a UV light, had the HD bulb on for the shot but it was off the rest of the time...

Currently sitting under a 600w HD lightbulb 2.5 feet above. One plant has grown slowly, one is a little too stretched but the rest are about as you would expect, Ice seems to naturally stretch IMO.

Temps. a little high as the fan has broken Humidity is only 10-20% is this going to cause me big probs? Should I get a humidifier in there?

Im not sure about nutrients, I have Forumulex should I put a 1/4 mixture into the water for the plants to suck up too?

I'd really like to see your progess growing ice. Keep posting pics if you can

Well your humidity is extremely low. Get some clear plastic cups od half of a 2 liter and put them over the seedlings to act as humidomes

You should watch out for Alga it will grow on the rockwool cubes from the water and light. You need to have a gentle fan moving the air around your plants to strength up the stocks. Thick stocks allow for more nutrient up take when it's time to feed them nutrients.

I hope you are not feeding then yet?

Nope not feeding them yet, the leaves are growing big, worried they're starting to look a bit droopy?

Wooden Popsicle sticks work to prop them up. As well as coffee stirs work too plastic or wood. It will keep then standing straight until the stocks thicken up.

They're all Femanized seeds btw.

Don't use Wood popsicle sticks. They tend to rot from the dampness. Bamboo works great, plastic as well.
I agree with Z man as you should start air movement w/ a fan.
REALLY try to get yer humidity up, especially durring veg.

I would also like ta see pics of the ice. Also, when yer done, can ya post how good it smokes? And yer weight? I've only seen it on the web and none of my "buds" have tried it before...

All smiles, man.

I have wanted to get some Ice for awhile...very interested in this thread...

You say your getting the droops...What is your feeding schedule?

Also, you are right not to nute them until you see roots growing strongly out of r'woll cubes. then use no more than a 50% solution the 1st week.

As far as algae; Get some panda plastic at the hydro store and put black side down after cutting slits in plastic to allow you to slide it in around the stems of your plants.
you don't ever want to leave your roots exposed to light.

Little update

Image045.jpg

I've put a black cover over the seedlings to stop any light getting to they're roots. My humidiity is still very high, even with the bowls of water i've placed on the tables and a damp towel hanging in the tent also.

Seems nothing short of getting a humidifier will do the job :/

A few plants are drooping a little, though I might have over-watered them a little. Since the temp and humidity is so high they have been drying out so i've been dipping the bottom of the rockwool block in 5.5 water for them to absorb. Not too much though, most of them are looking great and firm with good colour.

Most of my probs are temp and humidity I believe.

Not feeding them yet, was going to give it another week...?

Dude there is no way in hell they would rot or cause problems. They are only used for about 2 weeks. Rotting takes several months not day's.

Popsicle sticks are fine for the short term you will need them.

Keep thinks in perspective MrGuy you over reacted. What lead you to think they would be used for the whole grow? Because I did not post a time limit? Common sense goes a long way even in forums.

I'm not going to be able to get my hands on a humidifier for a week or so, I was wondering, if I put the whole NFT system up and running then the running water will raise the humidity and lower the temp a little?

Not with nutrients but just with php water, or would that drown them too much? I have liquid oxygen...

you can run your entire system, only using a few sites, won't hurt anything...

you just stated high humidity over and over...didn't you mean low humidity? high humidity would be hot/damp; Not hot/dry
do you have AC...

Yeah I meant low humidity. 10-20% low.

I have a Systemair fan and Carbon Filter I have put on, plus a fan going well in there. The room itself is pretty chilly with a good breeze through an open window. (The tent is usually zipped up though)

Temp under the light is 90degrees, at the top of the tent its 79.

cut-off the carbon filter, and it should not be inside your grow room, but outside. you don't need it until they start to stink up the place during 12/12. It could be removing humidity.

what is systemaire? could it be removing humidity.

With a tent and hydro, It is unusual to see that low of humidity...at least in my experience.

right now i've got the systemair fan sucking the air THROUGH the filter and blowing it out through a long piece of ducting. Should it be sucking the air through the fan and blowing it OUT of the filter? :s

What do you mean by that?

sorry, I mis-directed you above...I said carbon filter should be outside room. Well not necessarily; I was thinking of Ozonator and mis-spoke myself sorry.

As far as your Q about running entire system. I thought you mentioned something about setting up entire system and running water through it to create more humidity.

I said, that was a good idea

Thanks bud was worried about drowning them or something as I know your supposed to have quite a bit of root before going into system.

If you have roots, you can put them in system. your only concern would be if you fed them too strong a nutrient solution.

If you want to place them in system, running ph'd water and superthrive 1/4tsp per gallon or Liquid karma, follow direction's for seedlings; You will be OK.

Im about to put the young ones in the nft system and turn the pumps on. Should I stick to just 5.5 water or put Formulex to make it upto 12? Or put none in at all?

They're 2 weeks old, most of the plants are looking healthy, that one is looking a bit droopy and there is a runt in the bot left corner i'm going to see what happens with it.
