Sounds like they are stretching a bit. CHeapest thing you can do is head to a home depot or lowes and grab the cheapest regular fluros you can get. If you can only get one.....put it right over top...2 inches or less away from the plants. No heat so you have no problems there. Best bet would be one on top and one on either side. In seedling stage they can be left on for 24/7 cycle. After they get a little bigger then you can switch to 18 /6/ These lights go for about 19 bucks each. Also all you need is the cheapest BLUE fluros you can find....dont waste money on the SUNLIGHT ones that run about 6 bucks. Also a fan gently blowing on them will help strengthen the stems. NO NUTES OR ANYTHING ON THEM UNTIL WEEK 3....and even then it should be in a very diluted form. Good luck Opps also Superthrive works great when starting out....its not a nutrient so you can add a few drops to the water....really helps the roots develop.
Krippysmoker Reviewed by Krippysmoker on . Slow growth?... Im using an 80w flor (4ft long) about 5" above the plant... and a 100w UV+B Iguana light about 3' above it, all light is bent towards it with tin foil... Im using expensive potting soil... omigrow I think it was called. It gets about 18 hours of light a day, It gets watering when the soil starts to feel dry... Im using collected rain water, and liquid vitamin b drops, 2 drops per cup of water. In the future if and when I run short of rain water, I'll use tap that has sat for over 48hrs. Its Rating: 5
