400w Metal Halide for first month of flowering?

Top 44 is a quick finesher from what I am told, and Stinky is right.

BlueBear Reviewed by BlueBear on 12-06-2007. 400w Metal Halide for first month of flowering? Okay, right now i have a 600w HPS which covers a 3 x 3 area. I figure i can fit 6 comfortably. I was wondering... could i double what im doing by getting a 400w metal halide for the first 4 months of flowering then switch to the 600w hps for the the main budding phase. Someone was telling me that plants grow denser with sturdier stems under MH light, and since the first 3 -4 weeks is stretching could MH light help control stretch? Could a 400w MH keep up with 6 medium sized plants for a month Rating: 5

Bear, I sent you a letter back. It has been a very hard month- I'm sorry I took so long.

Hi peeps,

So, having read this thread I thought I would just get some clarification. Here is a picture of my great white sharks just entering their 5 week of veg. I'm planning to go to 12/12 within the next day or so and just wanted to make sure that the plan is correct. I'm going to keep the 400W MH going until I see them start to flower and then change over to a 400W HPS. The question is, would this be the best thing to do?

Under a 600 it takes skill, but with a fair hand it can be done. Need a nice strain that you can become familiar with and a good feeding schedule and a decent veg time unless you are going to go sog with 15 to 20 plants in that area. think about this, 8 zips are very doable with a 400W and they only have half the lumens as the 600 with allot less penetration. I haven't known many, but there are few who have even pulled a LB off a 400. I am not gifted like that unfortunately though.
There is a 600w club over at IC mag, you may want to check it out. I don't want to make you to over ambitious, so do a little more reading about what is a reasonable expectation for the 600 and just try to enjoy your grow, because when you get caught up in the numbers game you make this thing master and not a friend IMO.

A lot of growers like to stay with the MH for 1-4 weeks of flowering 12/12 cycle to reduce stretch in the plants. I like at least 5 weeks.

The white strains like White Shark do like to stretch. Those do look nice, at 5 weeks veg...:thumbsup:

Why not use both MHand HPS it wont hurt anything and you get both blue and the red light spectrum. My grow buddy uses a 1000 MH and a 1000 HPS and hes been using them for years.:rasta::rastasmoke:imp:
