Get 2 x 40W 'daylight' CFLs (can support 1-4 seedlings)
Answer: When marijuana seedlings are growing tall and thin like that, it means they need more light.
When young marijuana seedlings are starving for light, they often show signs of lots of other problems, but if they're getting really tall without making any leaves, it's a sure sign it needs a brighter environment.
Some growers bury the extra stem to make seedlings short again, which works, but as long as you start giving your seedling light it will do a "push up" and rise back up, strengthening its stem in the process! Here's what to do right away…
You can get more light later when the plant is making buds, but getting 2 CFLs should stop the stretching so you have a few more weeks.
To increase the amount of light, you either need to get stronger grow lights (what grow lights work for growing cannabis?), or move your current grow light closer to your plants.
Get 1-2 CFL bulbs and keep 2-3 inches away from the tops of your seedlings (be careful not to let seedlings grow into the light!)
