Veg/lighting Question

[rockinlespaul]

Both our lighting systems are switchable so we have the option of mh or hps at any time. One is a 1000, one is a 400.

 

My ladies are flowering under a 1000 watt hps. Behind them are some in veg under the 400 mh.

 

Normally we only put them under the 400 for a week or so then under the 1000 in mh mode until its time to switch bulbs and go hps flowering, but this was when we just ran a bunch all the way through. Now we are becoming perpetual...or trying to anyways, lol.

 

Since I have another month or so to go in flower, could I throw the vegging ones under the 1000 hps while its on then put them back under the 400 mh without any issues?

 

I'm concerned about possible hermies maybe. Any other problems you forsee doing this? I understand its optimal to use the mh, but I'd like to take advantage of the 1000 watts also if I can. Anyone? Thanks!

Are there two seperate light areas light proof from eachother? If so, I think you would be fine to take a late veg stage plant and move it under the 1000 as long as you move it back to the other light after each light cycle in the flower room. Are you running a timer on the 400 too? How many hours?

i do it every night @ 8 i have one light in the basement and a Small light upstairs just remember the amount of meds will be less on the other plants Say you have 2 plants under a 1000w and you get 2 oz per plant if you put 4 plant under a 1000w you will not get the 2 oz and if you put 6 under that same 1000w you get the picture

Yes. The flowering is done in a tent that is light proof. Veg is 18/6, flowering 12/12.

 

Lights come on at 6 pm. At 6 am, the tent gets zipped up tight. The 400 and a T5 continue to run till noon. Then lights out. So essentially, when everything comes on at 6pm, I'll take certain veg plants from under the 400 and put them under the 1000 till 6 am, then they go back under the 400 till noon then lights out.

 

I'm just concerned about them being under more hps than mh while vegging.

Wouldn't the change in light spectrum from the hps to mh stress the plants and cause them to possibly go hermi?

That's exactly what I NEED to know, lol. I've only done it twice so far and they are still pretty small.

[rockinlespaul]

No one?

 

I will stay on the safe side then and keep them under the 400 mh, lol.

 

Our first grow had zero seeds. I want to keep it that way.

, could I throw the vegging ones under the 1000 hps while its on then put them back under the 400 mh without any issues?

 

 

the simple answer is yes. it wont kill them anyways. is it 100% guaranteed issue free? not in the least. some hardier strains you could move to a diff wattage of light every day in flower and they would be fine.... but you will always have the weaker strains that carry a higher possibility to stress themselves into having fits and growing balls or airy buds. if this is going to be a constant thing in your grow room, then try it out on one plant..... if this is just a one time thing and you just want to take advantage of the extra lumens this once..... skip it.. play it safe.

Thank you very much for the advice. I am going to play it safe. Maybe lose the 400 and bump up to a 600 for vegging.

bonus info

 

introducing MH during flower is more apt to provoke the plant into producing very light and airy buds, than to make it grow male flowers. messing with the light cycle itself (timer 12/12) is just the opposite and you will see the effects of the stress in the form of male flowers more often.

Thank you for the bonus info!!! The 1000 gives us very nice thick hard buds. When we ran our fist grow thru, we put them under the 400 for just over a week then right under the 1000 mh and they remained very thick, healthy bushy plants.

 

The ones under the 400 now are not as bushy as the first run(cloned same strains)and I was wanting to do the 1000 watt thing to get them bushier. I think my answer may be a bigger light for veg...or at least it will help.

 

Thanks again for your help.
