wilting plant comeing back

I normally veg with 48" shop lights and then SMACK dab into 400w HPS. No problems EVER!

Now 5' is definately overkill. Once I induce flowering, I normally have the lights about 18-24" above the canopy with no problems at all.

I was told by another grower that if you have your plants under a low level light, and then strait into a HPS or High output. It can shock the plant. If the plants were doing well under the 300 meter reading They should be ok under the 500 it is receiveing now. I will see how they do in a week and if they boune back well I will lower it a bit.

did you ever check the heat the lamp was producing ?

exactly, even to 600 HPS. they may stretch a little more, but for me the more the better-the bigger the better. and I mean smack dab too.

Well all I can tell you is that the plants quit wilting and are bouncing back very nice. The light was a shock. Could be due to the fact that it was only one 2 foot flor 20w they were under, but the meter would only reg. 300 when the sensor was held on the flor itself. the HPS holding the meter 2 feet under when to 1000 and that was the end of the scale. So it was definatly light shock. I have been told by other growers that when a plant any plant is under low light even when taking outside you need to put them in shaded areas until they get used to the increas in light or they will shock. Your plants were under much more light with 48inch lights, and how many? I may or may not put the HPS lower, they are doing well right now and I do not want any more set backs. The water meter is helpful also, it is saying it is wet when the top is dry. I will let it dry out until the meter is reg. on the dry side down in several inches.
