Are your lights in a tube, or how would your blend the lights so one side isn't MH and the other HPS? I might beat you to it in the next month. Yeah MH will keep plants from stretching as much as they do with HPS, so I was told. Talking to a worker at my local grow store they thought using...

Will a MH yield at a similar gram per watt as a HPS? I'm going to up my lighting and am thinking of a 400 MH with 600 HPS in a 21" by 21" cooled reflector (growzilla) or two 600 HPS bulbs in a 4' cooling tube. Either way they will be in a 4' x 2' Secret Jardin. I am wondering about either...

Will a MH produce the same gram per watt as a HPS?

Damn I meant flower not veg in the post two above. I've been growing with a 600W HPS, has worked well but the bulb is getting old. I'm torn between getting two new 600W HPS in a 4' long cooling tube or a new 600W HPS with a 400W MH in a Growzilla (enclosed reflector 21"x21", exhausted). What...

This may be silly but why wouldn't the guy that started this thread veg with both lamps. 800W vs 400W would seem to be a nobrainer.

Yeah the jardin has a space blanket like material that is highly reflective as well. I wasn't speaking so much about the undergrowth but rather the colas on the plants on the sides compared with the colas of the plants that are directly under the lamp. Thanks

Thanks for the response. My worry is that if have my lights close as possible to the plants that the edges of the 4' area will not be getting enough light (or not the max possible). This isn't a problem with you, how many plants are you packing in the space? I guess I could rotate/move the...

I've been trying to decide between a 21" x21" (growzilla) reflector with a 400 MH and a 600 HPS or a 4' tube with two 600 HPS. I'm wondering if the 21x21 will produce enough spread of light cover the Secret Jardin 4'x2', this would be a much cheaper investment. I would also like to know the...

GrowTech, what are those black deals above your lights? I've been trying to find a nice and convenient way to adjust the height of my lights, and I'm guessing that's what you've got here. Thanks

I saw a guy asking about Colorado growing. I would be interested about the season in Northern NM as well. Spread some knowledge. Thanks

My indoor have been flowering for 2 weeks, I'm running out of space and planning on culling three. I thought I might just move them to my outdoor greenhouse. Does anyone know what will happen to these girls? I live in northern New Mexico. Thanks

A couple of my plants are becoming shaded out in an indoor setup. I'm planning on constructing a visqueen (sp?) structure inside of my glass greenhouse. Right now they are in coconut, what are the different watering requirements of filling larger pots with coconut or potting soil? Do I even...
