Hi there,
Im at my wits end... I have tried to grow hydro for 12 months on and off now and i always seem to roughly get the same result (i.e: nothing) no matter what I change and im running out of ideas....
So far I have tried
- different clones
- Tank water, Mains Water and Dam water
- Different ballasts and globes (both HPS600w)
- Different watering systems: Recirculation, runoff and by hand at the moment
- Different heights of hte light
- Different reflector
- full strengh Nutrients, 1/2 strength, and not at all.
A friend of mine uses the same lights and same medium and grows really well, but here I cant seem to do it. I thought that it might be the quality of the power running in, so I have the lights running off a UPS, but that has not helped.
I have attached photos of my clone box so you can see that the clones were / are nice and healthy to start with, but get them into my tent and they fall over (so to speak).
They get 18 hours a day and the fan runs 24x7.
The first 2 pics are from my clone box.
Im at a complete loss to explain it, I have tried just about everything I can think of and I get the same result. Please someone help!!!!
1. How tall are your plants now?
About 20 centimetres or so?
2. How far from the lights are the tops of your plants? Is this a constant distance or have you changed it recently?
It does not seem to make a difference.. I've tried close and tried 30-40cms and the result seems the same.
3. How old are they?
Technically they are about 10-11 months old, but they have been in the tent for about 3 weeks.
4. What strain are they?
Umm not sure
5. Did you start them from seed or clone?
Cloned from some that i used for outdoor last season which went great guns and produced nicely.
6. What type of containers are you using and what size are they in gallons?
Ummmm im not sure but the pictures show them
WHAT TYPE OF GROW DO YOU HAVE?
7. Dirt?
In a soilless medium. Same that I used for outdoor which worked fine. coconut husk stuff I think it is
8. What mixture of dirt or type of dirt did you use?
9. Is it a type that has added nutrients like "Miracle Grow"?
Not that I am aware of. It has fertiliser in it, but its the slow release kind.
10. What mixture of perlite, vermiculite and other additives have you used if any?
Nothing as yet
11. Hydroponic?
Yes
WHAT TYPE OF HYDROPONIC SYSTEM DO YOU USE?
12. Ebb and Flow
13. NFT
14. Bubbler/Deep Water
At the moment its just me hand watering it to try and 'tick off' any of the factors that could be causing it
WHAT TYPE OF MEDIA DO YOU USE?
15. Gravel
16. Hydroton
17. Rockwool slab
Ummmmmm
WHAT TYPE OF LIGHTS DO YOU USE?
18. Fluorescent
19. Halide

YES.. HPS
21. Wattage?
600
22. Ballast, is it digital or analog?
Im not sure the difference but I would assume analog?
23. Is it remote or in your grow area?
Its outside the tent with a 2-3metre power lead
24. What nutrients are you feeding your plants?
At the moment... nothing... just water to try and ascertain the root of the problem
HYDROPONIC FERTS?
25. What brand? What mix? What strength?
26. How often, and when was the last time?
At this stage... nothing.
SOIL FERTS?
27. What brand? What strength? What mix?

30. If so, what do you use?
31. Do you use a fan?
Tried a fan yes, no difference.

Just the standard pedastal fan that you would buy from the local hardware store. Tried facing it in all different directions.
