Here are some pictures from an LED Grow that we have running parallel to the 100 Watt CFL Grow that I have featured in recent posts. I thought it might interest readers to have a comparative peek at how buds look after 3 weeks of flowering under LED lamps compared to how they look after 3 Weeks under 100 (or so) watts of CFL.
I haven’t attempted to color-correct the raw images here – the LED lamps tend to create a psychedelic-looking deep red/purple light, whereas the CFL 2700k bulbs are more typical of what you’d expect in a room (soft white).
First of all, for those of you following our 100 Watt CF grow, here are pictures of the Dinafem Critical + (first) and Afghan Kush x Double Gum cross (second).
The AKxDG has recently made a more Sativa-like turn (despite the early indications of Indica-dominance due to the wide leaves), growing taller and leafier at the top, and with buds along the stem, instead of a dense cluster at the top. The Critical + plant is doing very well under the CFL lights, and promises to be an excellent producer under low-wattage conditions.
The following are shots of an LED grow (multiple 125 Watt lamps are in use) where we currently have an African Sativa land-race strain that has been flowering for just under 3 Weeks (started them just after the 100 Watt CFL grow plants):
Although LED lighting may be too expensive for the budget home grower, I feel that the added expense may be worth the upgrade over the long term. The buds under the LED lamps show healthier, more robust growth in a slightly shorter period of time – compare the fullness of the buds, and density of pistil growth to the above CFL grow pictures.
On the other hand, the startup costs for the CFL grow are next to nothing compared to an LED lighting rig! Stay tuned and we’ll see what the CFL plants look like next week as we start the 2 week (or so) countdown to harvest time.
