week and a half under repti glo 26w lights

What do you think of my seedlings after a week and a half under 3 26 watt repti glo uvb lights and 1 26w warm cfl all comments and critisim welcome

they look ok to me y not try sum sodium lights

looks great. you;re going to need more light soon. your soil looks a little dark. when you repot make sure to add something like perlite to improve drainage.

its a test to see how plants will grow under reptile UVB lights

it has 1-2" of lava rock in the bottom of the pot and perlite in the soil just watered before i snapped the pics

they will start to stretch soon if they dont get a bigger light but there fine for now

I had my plants under the ReptiSun bulbs.... They work pretty good... but I have seen a dramatic difference when I switched over to an 100W HPS... not only in plant growth but in heat reduction as well.......

these arent the heat producing bulbs for reptiles there are just for uvb

they are the repti glo 2.0's

Exo Terra : Products : Compact Fluorescent Bulbs

i start my plants of with a 150hps and they love me for it you should give it a try

i must say they look great very healthy.
hope you can keep it up.
have you got more lights for when they grow bigger?.
or what are you going to use ?
and for 12/12?.

nice looking plants.
what strain?.

i have a good hps set up this is just a test since i couldnt find any real information on UVB lighting

dunno the strain just bag seed

my theory with the uvb light is it will produce a hardier plant with thinker foliage due to it having to adapt to the burning effect of the UVB radiation

dont use it for to long it will dry ur plant out and kill it

if it kills them it kills them its a test to see how they do they have been exposed to the lights 24/0 since the seed went into the pot most plants adapt to there birth eviroment and conditions very rapidly

all the best and i hope it turns out top smoke

Thanks

anyone use happy frog soil?

Ok! Here's my prediction. It wont really respond much to the UV lights at all. It will just stretch like a Mofo when it starts to outgrow the one warm CFL (why warm?).

The UV-b spectrum doesn't have much of a role in the veg phase, where a Daylight spectrum CFL (6,500 K) whould probably give better results. But maybe that's your point, to really deprive the plant of as much PAR (Photosynthetically Active Radiation) as possible with a boost in UV-b. What is your light schedual?

I would suggest testing two plants (identicle clones), both vegged under Daylight CFL's (6,500 K). Flower one under 3 UV's and one Warm CFL (2,700 K) and flower the other one under 3 Warm CFL's and one UV. Might show some intersting results, just my $.02 worth!

these lights are 6700k lights at 1970 lumens per bulb and a cri of 98
