what to do with Internode elongation

[Sleepyhead1]

What wavelength LED's are you using? Red (645)/Far red (>660) will result in node elongation (remove far red to fix it), as will a lack of blue (430,440,460). Blues specifically promote short internode spacing.

Ecxellent advice!!!!:rasta:

Sleepyhead1 Reviewed by Sleepyhead1 on 08-29-2007. what to do with Internode elongation I grew with T5 clfs an had perfect short internodes structure, but recently I have swiched to the LED lightening and now I have plants growing with long internodes, more of that on one node i have only one branch (vegetative axillary bud) and a leaf, hoever I want to have two branches and two leafes on each node. What could be the couse of the problem. Lower temps, light spectra, light cycle (at 18/6 now mothers and clones grow in the same cabinet)? Thankyou Rating: 5
